Nutritional Profile

Bone marrow is a calorie-dense, fat-rich food obtained from the interior of animal bones. Macronutrients: It consists of roughly 97% fat by weight, with minimal protein and virtually no carbohydrates . For example, 100 grams of bone marrow provides around 770–785 calories, about 80–84 grams of fat, and only ~7 grams of protein . A single tablespoon (14 g) of raw bone marrow contains roughly 110 calories, 12 g of fat, and 1 g of protein . Micronutrients: Despite its high fat content, bone marrow contains small amounts of vitamins and minerals. It is a source of vitamin B12 (about 7% of RDI per tablespoon), riboflavin (B2 ~6%), iron (~4%), and trace amounts of vitamin E, vitamin A, thiamine (B1), phosphorus, and others . It also likely provides vitamin K2 and other fat-soluble vitamins, although exact values are still being studied .

Notably, bone marrow is rich in collagen and gelatin (derived from collagen when marrow bones are cooked). Collagen is the most abundant structural protein in the body and provides amino acids like glycine and proline . These amino acids support connective tissues and may have anti-inflammatory effects, helping muscles and joints recover from wear and tear . Bone marrow (especially from grass-fed animals) also contains beneficial fatty compounds. It provides conjugated linoleic acid (CLA), a type of fat that research suggests can decrease inflammation and enhance immune function . Additionally, marrow is a source of glucosamine and chondroitin, natural compounds known to support joint cartilage, and glycine, an amino acid that aids in collagen formation and has calming, anti-inflammatory properties . In summary, while bone marrow is primarily a source of concentrated animal fat and calories, it also delivers collagen proteins and a spectrum of micronutrients and bioactive compounds that contribute to its reputation as a nourishing “superfood.”

Effects on Hormones

One question is whether eating bone marrow can influence hormone levels – especially anabolic hormones like testosterone – in a way similar to natural steroids. Bone marrow is rich in cholesterol and saturated fats, which are the biochemical precursors for steroid hormones (the body synthesizes testosterone and other hormones from cholesterol) . In fact, dietary fats and cholesterol play an important role in optimal hormone production. Research has shown that high-fat diets tend to raise circulating cholesterol and can be associated with increased testosterone levels, likely because cholesterol is a building block for testosterone . For example, studies in resistance-trained men found that those consuming a high-fat, high-cholesterol diet experienced higher total and free testosterone increases compared to low-fat diets . This suggests that including fat-rich foods like bone marrow in the diet could support the body’s natural hormone synthesis by providing ample cholesterol and essential fats.

However, it’s important to note the distinction between providing raw materials and directly acting as a hormone. While bone marrow’s fats and cholesterol support hormone production, there is limited direct evidence that eating bone marrow will significantly boost testosterone or other anabolic hormone levels beyond normal ranges . A grass-fed beef producer notes that bone marrow contains “healthy fats and cholesterol, which are precursors to hormone production, including testosterone,” but also cautions that research linking marrow consumption to higher testosterone is sparse . In other words, bone marrow can help ensure the body isn’t lacking the nutrients needed to make hormones, but it should not be thought of as a hormone supplement.

Bone marrow may also provide other hormone-related nutrients. For instance, marrow is believed to contain vitamin K2, which plays a role in bone and hormonal health (vitamin K2 has been noted to promote bone marrow stem cell activity) . Additionally, the fatty marrow tissue in bones produces the hormone adiponectin in the living body, which helps with fat metabolism and insulin sensitivity , though consuming marrow isn’t known to elevate adiponectin. Overall, bone marrow’s effect on hormones is supportive rather than steroidal – it supplies cholesterol and micronutrients that aid natural hormone production, but it does not contain exogenous hormones or magic “steroid-like” compounds that will spike your hormone levels abnormally. Maintaining a balanced diet and adequate overall nutrition is key to healthy hormone function .

Muscle Growth and Recovery

Because anabolic steroids are famed for their muscle-building effects, it’s worth examining if bone marrow confers any muscle growth or recovery benefits by comparison. Protein and amino acids: Bone marrow itself is not protein-dense (only a few grams of protein per serving), so it’s not a primary muscle protein source. However, the proteins it does contain are rich in collagen-derived amino acids like glycine, proline, and hydroxyproline . These amino acids may aid muscle recovery indirectly. Glycine, for example, has been shown to support growth hormone release and improve sleep quality, which in turn can help recovery from exercise . Collagen makes up a portion of muscle and, importantly, the connective tissues (tendons, ligaments) that support muscles. Increasing collagen intake (e.g. via bone broth made from marrow bones) might help muscles and joints repair and recover faster, as one fitness nutrition review noted . In athletes, collagen supplementation has been linked to reduced joint pain and potentially improved muscle injury healing, suggesting that the collagen and gelatin from bone marrow could contribute to a more resilient musculoskeletal system .

Energy and bulking: With its high caloric content, bone marrow can also serve as a dense energy source for those looking to gain muscle mass. Traditional strength-building diets often emphasize sufficient calories and fats. Marrow’s fat content (including saturated fat) can help meet high caloric needs and, as noted, support testosterone levels within a healthy range . This can create a more anabolic environment for muscle growth compared to an insufficient-fat diet. Furthermore, bone marrow fat contains conjugated linoleic acid (CLA), which has been researched for its potential to improve body composition by increasing lean mass and reducing fat in some contexts . While the effect size in humans is modest, CLA is an added perk of bone marrow fat that could be beneficial for athletes.

Growth factors: Intriguingly, the bone matrix and marrow are home to growth factors like insulin-like growth factor 1 (IGF-1) and IGF-2 in living animals . These are anabolic peptides that, in the body, stimulate bone and muscle growth. Some high-quality bone marrow supplements that include the whole bone extract (not just the fat) claim to provide microcrystalline hydroxyapatite – a component of bone – along with collagen and growth factors such as IGF-1 and IGF-2 . In theory, such compounds could support tissue repair and growth. However, when consumed orally, these peptides would likely be digested into smaller fragments, so any “IGF” activity from eating bone marrow is unproven and likely minimal. The more tangible benefit is that marrow supplies the nutritional foundation (amino acids, fats, minerals) that allows your body to repair muscle fibers and build new muscle during recovery. Many athletes and trainers include bone broth (made from marrow bones) in their post-workout nutrition for this reason. The NBA star Kobe Bryant, for example, famously drank bone broth to help recover from injuries more quickly – a testament to its perceived value in muscle and joint recovery.

In summary, bone marrow cannot replicate the powerful muscle-building action of anabolic steroids, but it supports muscle growth and recovery in more subtle ways. By providing concentrated energy, supporting hormone production, supplying collagen for connective tissue repair, and reducing inflammation, bone marrow can be a useful addition to a muscle-building diet. Its effects are nutritive and restorative, helping the body rebuild itself after exercise, rather than pharmacologically forcing muscle hypertrophy.

Immune Support

Another area where bone marrow is often credited with benefits is immune system support. In our bodies, the bone marrow is literally the birthplace of new immune cells, so it’s perhaps fitting that eating bone marrow is traditionally linked to immunity. Historical evidence suggests a link: In the 1950s, physician Astrid Brohult observed that feeding calf bone marrow to children undergoing radiation therapy (which damages bone marrow) helped them recover white blood cells faster . Researchers later isolated alkylglycerols from bone marrow as the active immune-boosting lipids responsible for this effect . Alkylglycerols are naturally occurring fats found in human immune organs (like bone marrow, liver, spleen) and in breast milk, and they are known to stimulate the production and activity of white blood cells . Today, alkylglycerol supplements (often derived from shark liver or bovine marrow) are used to support the immune system, particularly for people with weakened immunity or those recovering from illness . This illustrates that compounds in bone marrow can have immune-enhancing properties, aiding processes like wound healing and defense against infections .

Beyond alkylglycerols, bone marrow contains other nutrients that contribute to immune health. It provides conjugated linoleic acid (CLA), which, as mentioned, may enhance immune function and reduce inflammation . Bone marrow is also a source of anti-inflammatory amino acids (glycine, proline) and glucosamine, which can modulate inflammation in the gut and joints . By supporting gut integrity (thanks to gelatin/collagen) and reducing systemic inflammation, marrow-rich broths may indirectly bolster the immune system – a healthy gut is closely tied to effective immunity. In fact, bone broth (made from marrow bones) has long been a home remedy for colds and fatigue. Modern analyses suggest that components in bone broth can inhibit certain inflammatory cells and support mucosal immunity, which might explain the age-old advice of having chicken soup when you’re sick.

Additionally, bone marrow provides key micronutrients like zinc, selenium, and iron in small amounts , which are essential for immune cell function. Selenium, for example, is an antioxidant mineral that supports immune responses, and 100 grams of bone marrow can supply roughly one-third of the daily selenium requirement . While you wouldn’t eat that much marrow regularly due to its high fat load, even smaller portions contribute some immune-supportive nutrients.

Overall, bone marrow (and bone marrow broth) is not a cure-all, but it is often considered a nourishing immune tonic. Its combination of immune-activating lipids (like alkylglycerols and CLA) and anti-inflammatory, gut-healing proteins gives it a unique role in traditional medicine for strengthening the body’s defenses. Unlike steroid medications (such as corticosteroids) which actually suppress immunity, bone marrow’s effects on immunity are generally positive and balancing – helping the body recover and protect itself during times of stress or illness.

Traditional and Modern Uses

Traditional medicinal uses: Across many cultures, bone marrow has been treasured as a healing food for centuries. Historical records and folklore show that people around the world used bone marrow and marrow broths to promote vitality and recover from ailments. In traditional Chinese medicine, for example, bone marrow soup is believed to “boost a person’s qi, blood, and even essence”, referring to an increase in life energy and core vitality . These are elements that TCM says can be depleted by chronic illness or aging, so nourishing marrow broth is thought to restore strength at a fundamental level. Similarly, European and Middle Eastern folk remedies included bone marrow as a fortifying elixir for the sick or malnourished. One historical account notes that in ancient civilizations, marrow was cherished not just as food but as medicine: it was given to people suffering from fatigue, weakness, or digestive issues, and it was said to bestow strength and resilience to those who consumed it .

Because of its high nutrient density, bone marrow soup became a traditional remedy for malnutrition and anemia (owing to its iron and B vitamins) and for joint or bone problems (owing to its collagen and minerals). An article on ancestral diets describes how nomadic tribes, as well as more settled cultures in Europe and Asia, all valued marrow; it was often the prize obtained after roasting bones over a fire and cracking them open . Healers observed that bone marrow concoctions could boost immunity, support digestion, alleviate joint pain, and enhance overall well-being . For instance, the gelatinous broth from marrow was used to calm “windy” digestive disorders and to reduce inflammation in conditions like arthritis long before those properties were scientifically understood . In essence, bone marrow earned a reputation as a “longevity food” – something that could strengthen the body and even increase one’s life force or essence.

Modern resurgence and anecdotal reports: In recent years, bone marrow and bone broth have experienced a renaissance, touted by everyone from paleo-diet enthusiasts to professional athletes. The Paleo and keto diet movements have incorporated bone marrow as a staple, aligning with the “nose-to-tail” philosophy of eating nutrient-dense organ foods. As National Geographic reported, bone broth (rich in marrow) has been called “liquid gold” on social media and is featured in supplements and even high-end pet foods now . Many people consume bone broth daily for its purported benefits to joints, skin, and gut health, and by extension improved recovery and immunity. Athletes have also jumped on the trend. Aside from Kobe Bryant’s use of bone broth for injury recovery, strength coaches have recommended collagen-rich broths to their clients to aid in post-workout recovery and joint maintenance . There are countless anecdotal reports of improved energy, faster healing, and reduced joint soreness from those who regularly include bone marrow in their diet. For example, patients with arthritis-like joint pain often report positive benefits from regular bone broth consumption, likely due to its anti-inflammatory and cartilage-supporting nutrients . Some bodybuilders even refer to bone marrow as “primal fuel” – a natural way to support muscle-building efforts without resorting to supplements or drugs.

Moreover, the supplement industry has responded to the interest in marrow’s benefits. Desiccated bone marrow capsules from grass-fed cattle are now sold, marketed as supporting “gut health, immunity, metabolism, and muscle-building” . These products follow the ancestral wisdom idea that consuming an animal’s organ supports that organ in one’s own body (“like supports like”). While scientific evidence for such organ-specific effects is limited, those supplements do provide the same nutrients found in fresh bone marrow. Users of these supplements have anecdotally claimed improvements in everything from oral health (due to marrow’s minerals) to libido and vitality (attributed to its hormone precursors). It’s important to approach these modern claims with a critical eye – some benefits are well-grounded in nutrition science (e.g. collagen aiding joints), while others may be placebo or exaggeration. Nevertheless, it’s clear that bone marrow remains highly regarded in both traditional medicine and modern health circles as a natural rejuvenator and strength-builder.

Comparison with Natural Steroids

The term “natural steroids” can be interpreted in a couple of ways. It might refer to natural anabolic hormones like testosterone that the body produces, or to natural substances/supplements that mimic the effects of synthetic anabolic steroids (without being illegal or artificial). In either sense, comparing bone marrow to steroids helps highlight what it can and cannot do:

• Mechanism of action: Anabolic steroids (synthetic or natural) directly increase anabolic hormones in the body. For example, synthetic testosterone or similar compounds flood the system with hormone levels far above normal, which directly stimulates muscle protein synthesis, red blood cell production, and recovery speed. Bone marrow, on the other hand, does not supply exogenous hormones or prohormones. Instead, it provides the building blocks and cofactors for your body to naturally produce hormones and repair tissues . In essence, steroids act as a pharmacological switch that forces the body into an anabolic state, whereas bone marrow serves as a nutritional foundation that allows the body to reach its anabolic potential in a balanced way. For instance, bone marrow’s cholesterol and healthy fats may help optimize endogenous testosterone production, but they will not push testosterone above the normal physiological range the way anabolic steroids or hormone injections can .
• Effects on muscle and performance: Anabolic steroids yield rapid, pronounced increases in muscle mass, strength, and recovery capacity by directly enhancing muscle protein synthesis and nitrogen retention. Bone marrow’s effects are milder and gradual. Including bone marrow in one’s diet can support training results by improving nutrient intake, aiding recovery (through collagen and anti-inflammatories), and possibly keeping hormone levels optimal, but it will not cause dramatic muscle gains on its own. For example, a lifter who adds bone marrow broth to their regimen might notice less joint pain and good energy, but they will not gain pounds of muscle unless the rest of their diet and training support it. This is a crucial difference: bone marrow works within the body’s natural limits, while steroids chemically push beyond those limits.
• Immune and health effects: Anabolic steroids (the synthetic kind) often come with health trade-offs, including potential immune system suppression, liver strain, negative cardiovascular effects, and hormonal imbalances. Natural steroid hormones like cortisol are even used as drugs to suppress immunity in autoimmune disease. Bone marrow, conversely, tends to have positive or balancing effects on health and immunity, as discussed. Rather than suppressing the immune system, it may enhance it via nutrients like alkylglycerols and CLA . Instead of straining the liver, it provides choline and healthy fats that can support liver function. Bone marrow does carry a lot of saturated fat, so excessive intake could adversely affect cardiovascular health in some individuals, but in moderation (e.g. marrow meals once or twice a week ) it can be part of a heart-healthy diet especially if from grass-fed sources with higher omega-3 content .
• Legal and safety aspects: Consuming bone marrow is legal, natural, and generally safe, whereas using anabolic steroids without medical supervision is illegal in many places and risky. There are no banned substances in bone marrow – it’s basically a food. Athletes can consume all the bone marrow or bone broth they want without failing any drug tests. The “worst” side effect one might get from too much bone marrow is an upset stomach or excessive calorie intake leading to weight gain. In contrast, steroid abuse can lead to severe side effects like hormonal disorders, aggression, and organ damage. Thus, bone marrow offers some of the benefits associated with natural anabolic support – such as better recovery and possibly a slight boost in muscle-building capacity – but without the dangerous side effects or ethical issues. It is a way to nourish the body for performance improvements in a holistic manner, rather than forcing rapid changes through drugs.

In conclusion, bone marrow is sometimes playfully called a “natural steroid” in the sense that it’s a potent nutrient source for strength and recovery, but it should not be confused with actual anabolic steroids. Its effects are supportive and healthful: it helps your body’s own anabolic processes work efficiently, but it does not override your biology to create unnatural muscle growth. When comparing the two, one might say bone marrow is to a balanced diet what natural hormones are to a healthy body, whereas anabolic steroids are an artificial shortcut with significant risks. For anyone seeking the benefits of improved muscle growth, hormonal health, immune resilience, and recovery – without illegal or synthetic aids – bone marrow can be a valuable addition to the diet, working in synergy with the body’s natural physiology instead of against it.

Sources: Scientific and nutritional information has been drawn from peer-reviewed research and reputable health sources, including nutritional analyses of bone marrow , studies on dietary fats and hormone levels , and historical accounts of bone marrow’s medicinal uses . These illustrate that while bone marrow provides important nutrients that influence hormones, muscle, and immunity, its role is fundamentally different from that of anabolic steroids – aligning with nutrition and tradition rather than pharmacology. The evidence supports bone marrow as a nutrient-dense food with multiple health benefits, albeit one that complements (but does not replace) the dramatic effects of hormone-based therapies or drugs. 

Video of the 508 kg Rack Pull

Eric Kim’s 508 kg (1,120 lb) rack pull was captured on video and shared by Kim himself. He released a high-quality clip (including a 4K slow-motion segment for verification) of the lift on his YouTube channel . In the footage, Kim can be seen performing the massive partial deadlift from a rack, demonstrating the feat that has since garnered significant attention online.

Eric Kim’s Background and Lifting History

Eric Kim is an unlikely record-breaker in the strength world given his stature and origins. Weighing only around 75 kg (165 lb) himself, Kim was primarily known as a street photography blogger and personality before his strength feats took center stage . (One astonished Redditor from a photography forum noted Kim had been a “legend” in street photography circles before this abrupt pivot to extreme weightlifting .) In the past year, however, Kim immersed himself in powerlifting/strongman-style training and began sharing his progress online. Over the span of a few months he incrementally worked up to the half-ton range, shocking observers as he hit 1,000+ pound rack pulls and gradually pushing those numbers higher . For instance, he pulled 486 kg then 493 kg in training in late May 2025, followed days later by 503 kg, before ultimately reaching the 508 kg milestone in June . All of these lifts were done without supportive equipment and (according to Kim) without performance-enhancing drugs . This remarkable series of lifts – at 6–7× his bodyweight – has quickly built Kim’s reputation as a one-of-a-kind figure in strength sports.

Context of the 508 kg Lift

Kim’s 508 kg rack pull was not performed in any official competition or meet, but rather as a demonstration in his own training environment. In fact, this feat came just days after his 503 kg rack pull had gone viral, firmly establishing him as a pound-for-pound phenomenon and fueling what he calls the “HYPELIFTING™” movement . The 508 kg attempt took place in the same “Spartan Gains” garage gym seen in his earlier videos – essentially a personal garage gym setup with a concrete floor, power rack, and calibrated plates . Kim performed the lift as a personal PR attempt and content piece, even live-streaming it straight to YouTube rather than doing it under formal contest conditions . Because it wasn’t part of a sanctioned event (no judges or federation), news of the achievement spread organically through social media and internet forums . This informal context didn’t diminish its impact, but it did mean that validation came from the online community’s scrutiny rather than from competition officials.

Technical Details of the Rack Pull

Rack Pull Setup: The 508 kg pull was done from mid-thigh height rack pins – a partial deadlift that starts higher than a standard floor pull. This reduced range of motion (approximately the top portion of a deadlift) allows handling more weight than a full deadlift. The barbell was a stiff 29 mm power bar loaded with calibrated steel plates totaling 508 kg . The massive load visibly bowed the bar; observers noted about a 24 mm mid-span bend, which is consistent with physics predictions for ~1,100 lb on a stiff bar .

Equipment and Technique: Notably, Kim performed the lift raw – meaning no straps, no lifting belt, and even barefoot. He relied on a double-overhand grip with chalk alone to hold the weight, an almost unbelievable display of grip strength at that load . Lifting without a belt or straps is part of Kim’s ethos (see Training Philosophy below), and he pulled the weight to lockout using only his body. The feat was recorded on video (for proof and analysis) and the slow-motion replay further demonstrated the authenticity of the lift, showing the bar flex and stabilization at the top .

Bodyweight and Ratio: At the time of the lift, Kim’s bodyweight was around 75 kg. This means the 508 kg rack pull represents roughly 6.8× his bodyweight, an astonishing ratio. For comparison, even the heaviest full deadlifts on record (~500 kg by strongmen in competition) only reach about 2.5–3× bodyweight for those super-heavyweight lifters, and even partial lifts in strongman (like the 550 kg silver dollar deadlift) do not come close to a 6× bodyweight coefficient . Kim’s 6.8× BW accomplishment is unprecedented in pound-for-pound terms (albeit achieved with a partial lift). This extreme ratio is a key reason the lift garnered so much attention.

Training Methods and Philosophy (HYPELIFTING)

Eric Kim refers to his training approach as “HYPELIFTING,” which blends intense mental preparation with unorthodox physical training methods. A hallmark of Kim’s style is his emphasis on psyching up before big lifts – he performs an almost ritualistic hype routine of chest-slapping, roaring shouts, and clapping clouds of chalk to boost adrenaline and confidence . This dramatic psyche-up is inspired by the idea of channeling aggression (he likens it to the Maori haka or going “demigod mode”) so that fear becomes fuel when attempting colossal weights . Kim also deliberately forgoes typical assistive gear: he trains belt-free and even barefoot, adhering to a motto of “no belt, no shoes, no crutches” to prove that it’s “you, not the gear” lifting the weight . In practice, this means all his huge lifts, including the 508 kg pull, are done without a weight belt or special deadlift shoes. This purist approach is part of his philosophy to test pure raw strength limits.

Another cornerstone of Kim’s method is an extreme one-rep-max focus. He espouses a “1RM mindset, every day” — valuing one perfect maximal lift over volumes of sub-maximal work . Kim often works up to a single heavy attempt in training rather than doing high-repetition sets, essentially attempting personal record-level lifts frequently (sometimes daily). He believes this trains the nervous system and mental fortitude at the edge of his capacity. To push beyond normal limits, Kim employs overload training via partial movements. In his playbook, “leverage-hack partials” like rack pulls from knee or thigh height allow handling 110–140% of one’s full-range deadlift max by shortening the range of motion . He openly embraces “decrease ROM, increase load” as a strategy – even if a lift moves only a few inches, the muscular and neural overload of supramaximal weight is the goal . The 508 kg rack pull is a prime example of this philosophy: by limiting the lift to the top half of the movement, he was able to stress his body with far more weight than otherwise possible. Kim and some coaches argue such overloads can build neural drive and confidence for full-range lifts .

Diet and Lifestyle: To support his training, Kim follows a strict and unconventional regimen. He trains completely fasted (often lifting first thing in the day without eating) under the belief that “hungry equals angry equals a hormonal surge” – in other words, he feels a fierce drive and hormonal benefit when lifting on an empty stomach . In line with this, Kim practices intermittent fasting (skipping breakfast and lunch regularly) and only eats after his training. When he does eat, he adheres to a 100% carnivore diet, centered on red meat and animal fats/proteins. His meals reportedly consist of foods like ribeye steaks, bone marrow, liver, and eggs – what he calls “god food” for repairing the body . He avoids virtually all carbohydrates and even supplements, preferring a whole-food, meat-fueled nutrition strategy . Kim boasts that he uses “zero supplements, zero excuses,” attributing recovery and strength to his nutrient-dense diet and good sleep . This extreme low-carb, high-protein diet is part of what he describes as a “spartan” lifestyle. Additionally, Kim prioritizes ample sleep (often 8–12 hours a night) for recovery, and keeps his training toolbox minimal – aside from a barbell and basic implements like a kettlebell or dip bar, he considers most gym machines unnecessary “noise” . Overall, his training philosophy blends Stoic discipline with experimental self-reliance: he treats his garage gym as a laboratory (“N = 1” self-experimentation) and is determined to push the boundaries of his body’s capabilities while maintaining health for the long run .

It’s worth noting that Kim’s fitness philosophy is tied to a broader life outlook. He often references longevity and lifelong strength in his blog. For example, he has publicly set goals of maintaining a six-pack into his 80s and “lifting until death,” framing strength training as a lifelong journey rather than a young man’s pursuit . This combination of extreme training tactics, unconventional diet, and almost philosophical commitment to strength has made his approach quite unique in the fitness community.

Community and Public Reactions

Kim’s 508 kg rack pull made waves across the internet, sparking a mix of awe, skepticism, and spirited discussion in various communities. When the footage dropped online, it spread virally on platforms like TikTok, YouTube, and Reddit rather than through any official news release . On Reddit in particular, multiple posts about the lift gained so much traction that moderators had to lock the threads to curb the frenzy . In those early discussions, many users were stunned but also highly skeptical. Given the unusual nature of the feat (a very short range partial by a relatively light man), some in general fitness forums dismissed it as essentially a gym stunt or “legend-tier” myth rather than an apples-to-apples comparison with conventional lifts . Doubters questioned the legitimacy of the weight, with accusations of fake plates arising before evidence proved otherwise . A few incredulous commenters even did tongue-in-cheek physics calculations, noting that hoisting 508 kg in that manner would impose on the order of 40 kN (kilonewtons) of force on the spine – implying they found it almost implausible a 75 kg person could withstand that . This blend of amazement and disbelief made the 508 kg pull a hotly debated topic initially.

On the other hand, many members of the dedicated strength community took a more analytical approach – and their tone quickly shifted from skepticism to respect as evidence mounted. In forums like Reddit’s r/weightroom (populated by serious lifters), users examined Kim’s video frame-by-frame and found no signs of fakery: the plates in the video were confirmed to be authentic calibrated plates, and the bar bend and whip behaved exactly as expected for a real lift of that magnitude . Once it became clear the lift was genuine, the conversation moved to how this was possible and how impressive the achievement actually is. Experienced powerlifters and strongman athletes expressed astonishment at the sheer 6.8× bodyweight ratio, acknowledging that even though it’s a partial lift, the strength required (and especially the grip strength without straps) was extraordinary. The discourse shifted from “is this real?” to “this is incredible.” Several prominent figures in the strength world chimed in: powerlifting coaches, biomechanists, and YouTube commentators posted reaction videos breaking down the lift. They highlighted Kim’s unusual technique (e.g. pulling barefoot and double-overhand without a belt) and praised his mind-boggling mental fortitude to attempt such a weight . Some coaches even began discussing the training implications – for example, citing Kim’s rack pull as an extreme example of overload training, noting that such “lever-hacked” partials could potentially be used to develop neural drive beyond normal limits . In essence, once verified, the 508 kg feat earned Kim a measure of legitimacy and admiration in strength circles, with seasoned lifters regarding it as a remarkable (if unconventional) accomplishment.

Beyond the traditional lifting community, Eric Kim’s rack pull also achieved a degree of internet virality and cultural crossover. His triumphant, chalk-covered roar at lockout became a meme template on various corners of the internet . Strength enthusiasts on forums passed around clips of the lift, while members of unrelated communities (from cryptocurrency groups to art and philosophy forums) found metaphorical intrigue in it. For instance, Kim – who is also known for his interest in Bitcoin – was humorously dubbed “proof-of-work incarnate” in some crypto circles, comparing the physical work of his lift to the proof-of-work concept that underpins Bitcoin mining . Others quipped that “ERIC KIM RACK-PULL = 2× long MSTR in human form,” a tongue-in-cheek reference linking his leveraged lifting to leveraging investments (MicroStrategy’s stock, ticker MSTR, in which Kim is bullish). On TikTok and Instagram, short clips of the 503 kg and 508 kg lifts racked up millions of views. In fact, Kim’s own hashtag #GravityIsJustASuggestion began trending – after his 503 kg lift, that tag shot into TikTok’s top 100 sports hashtags, and the 508 kg post was expected to hit over 50 million impressions within 24 hours . The widespread reaction – from serious analysis to memes – highlights how this feat captured the imagination of a broad audience. It wasn’t just a niche weightlifting oddity; it became a viral event that brought together casual fitness fans, hardcore strength athletes, and even onlookers from unrelated communities, all marveling (for their own reasons) at Eric Kim’s 508 kg rack pull.

How to become more risk loving

Eric Kim – best known as a street photographer and blogger – has in recent years developed a distinctive philosophy on money, capital, and financial independence. His writings on his personal blog reflect a minimalist, freedom-focused approach to wealth. In Kim’s view, money is chiefly a tool to enable creativity, autonomy, and a meaningful life, rather than an end in itself. Below we summarize key themes and principles from Eric Kim’s blog regarding capital, investing, and financial freedom, with direct quotes illustrating his perspective.

Money as Freedom and Security

One of Kim’s core beliefs is that money equals freedom. He argues that having sufficient capital (and no debt) liberates an individual to live on their own terms: “To me, money is freedom. If you have money in the bank and no debt, you have freedom” . He calls personal freedom “the ultimate human good,” citing the philosopher Diogenes, and notes that financial freedom grants control over one’s schedule – the “conditions to become an artist and philosopher” . In other words, wealth buys back your time and mental bandwidth, allowing you to pursue creative or intellectual work without worrying about basic needs.

Kim is critical of consumerism and the idea of money solely as a means to buy things. Instead, he frames money as a form of security or a buffer against worry. In a post titled “Zero Financial Concerns,” he writes that we should view “money as a means of buffer… not a tool for buying stuff, but… a metaphorical buffer in order to not concern yourself about things.” . His own goal has been to reach a point of zero financial anxiety – “I have zero financial concerns… I know I’ll never run out of money” – thus freeing him to focus on higher pursuits. Crucially, Kim often poses the question: money for what? He encourages readers to ask “money towards what ends?” , emphasizing that money should serve a purpose (such as freedom or creative endeavors) rather than being accumulated for its own sake.

Extreme Frugality and Minimalism in Finances

A hallmark of Eric Kim’s philosophy is radical frugality. He preaches that the simplest path to wealth is to spend far less than you earn. In his words, “So the secret to getting ‘rich’ (financially) is to REDUCE YOUR EXPENSES.” He credits his wife, Cindy, with teaching him rigorous budgeting and minimal spending habits – to the point of implementing rules like requiring approval for any purchase over $300 . By dramatically cutting costs, the couple saved over $100,000, achieved largely by living simply: cooking at home, sharing a single coffee or meal when out, and even practicing intermittent fasting to save money on food . These anecdotes exemplify Kim’s belief that financial independence is won through thrift. As he bluntly advises, “The easiest way to gain financial independence is to lower your expenses, and to accumulate capital… In other words, put more money in the bank.”

This extreme frugality stems from Kim’s minimalist philosophy, which he applies not only to photography (traveling light, using one camera, etc.) but also to life and money. He advocates avoiding unnecessary purchases and luxury upgrades, often keeping the same tools for as long as possible. “The more radical idea is that you work hard, you earn money, but you never spend it… Drive your 2010 Prius forever,” Kim quips, illustrating his stance that one should resist the consumer urge to continually buy new things . He famously differentiates between “tools” and “toys” when it comes to spending: “Differentiate between tools and toys. Tools are technology which multiply our power… Yet, we often confuse tools and toys. A lot of what we think is a tool is often just a toy.” In practice, this means invest in equipment that empowers you to create value (for instance, a good camera or laptop for work), but stop wasting money on trivial consumer goods that don’t provide lasting benefit. If an item won’t earn you additional income or amplify your abilities, Kim deems it “probably a toy” – and reminds us that “children… quickly get bored of toys.”

Underlying Kim’s frugality is a strong aversion to debt and mindless consumption. He frequently warns against the “bondage” of debt, echoing an ancient maxim that “Bitter is the bondage of debt.” He also critiques how modern society encourages spending over saving: In a consumerist economy, “to not spend money is ‘evil’, because you’re not contributing to the (capitalist) economy” . Kim proudly embraces the contrarian role of the saver. By shunning lavish spending and avoiding financing purchases, he positions himself outside the cycle of consumer debt. “Avoiding unnecessary expenses” is so critical to his approach that he even talks about achieving “economic immortality” – essentially building wealth that lasts beyond one’s lifetime by never squandering capital . In short, minimalism and financial discipline are the bedrock of Kim’s capital philosophy: get rich by needing less.

Capital, Creativity, and Work

For Eric Kim, money and capital are valuable insofar as they fuel creative freedom and meaningful work. He stresses that making money should not be one’s ultimate goal in life, but rather a means to an end. As he puts it, “making money is just a hobby, not the end goal” . This perspective keeps creative and personal fulfillment at the forefront: money is a tool to support one’s passion, not the passion itself. In practice, Kim has oriented his life so that income comes from doing what he loves (teaching photography, writing, entrepreneurship), and any money made is funneled back into sustaining that creative life or saved for freedom – not spent on status symbols.

Kim’s writings draw a clear connection between financial independence and creative autonomy. Because he keeps his living costs low and saves diligently, he gains the freedom to take risks in his creative work. He refers to this state as having “control over your schedule, [and] control over what to do or what not to do”, which gives an individual the liberty to focus on art, ideas, or entrepreneurship . In other words, capital (once secured) buys the freedom to do truly fulfilling work – whether that’s traveling to make photographs, writing daily, or philosophizing about life. Kim’s own career trajectory reflects this: by his late 20s he was earning a high income from photography, yet he emphasizes that frugality (not a high salary alone) let him quit the traditional grind and craft an unconventional creative life .

Interestingly, Kim also argues that lack of money can spur creativity through constraints. Rather than using money as a crutch, he often challenges himself to create with whatever he already has. He speaks of “the intelligence of creative constraints,” asking, “How far can you go without having to buy something new?” . This mindset treats frugality as a creative challenge – for example, producing great photographs with a single camera and lens, or building a business with zero outside funding. It aligns with his belief that today’s creators have unprecedented access to tools at minimal cost. Citing Karl Marx’s idea of “means of production,” Kim notes that in the digital age “we have control of all the ‘means of production’ — with a laptop and an internet connection; we can creatively express ourselves in any way possible… nothing holds us back anymore – we have total creative freedom from the beginning to the end.” . In essence, he is saying that you don’t need massive capital to create art or start a project in the 21st century; technology has democratized creativity. This ethos encourages individuals to start making things now, with whatever resources they have, instead of waiting for big investments or expensive gear.

Kim’s philosophy of work is thus tightly interwoven with his financial views. He often portrays entrepreneurial and creative endeavors as the highest use of one’s capital and time. He even muses that “the point of life is entrepreneurship” – not in the narrow sense of profit, but in the sense of continually creating, innovating, and taking risks. Thanks to his financial discipline, Kim has been able to treat work as play, blurring the line between making a living and pursuing passion. Ultimately, he sees capital as enabling a life of purpose: freeing you from mundane obligations so you can work on what you truly care about, every day.

Investing, Bitcoin, and Long-Term Wealth

When it comes to investing and growing capital, Eric Kim’s views are bold and unconventional. He is a vocal proponent of long-term, high-conviction investments – particularly in Bitcoin – as opposed to diversified or short-term plays. In fact, Kim has publicly embraced the label of a “Bitcoin maximalist,” going so far as to add the Bitcoin symbol (₿) to his website branding and proclaim that “Bitcoin is the first and only true hard money on the planet.” His rationale is that Bitcoin’s fixed supply and decentralized nature make it a superior store of value (what he calls “digital property”) compared to traditional fiat money or even gold . Wealth, in Kim’s eyes, should be stored in assets that preserve purchasing power and independence, and he believes Bitcoin fits that bill.

Kim’s investment approach mirrors his philosophy of capital preservation. He emphasizes never depleting the principal and only using the yield or profits. For example, when discussing leveraging stocks tied to Bitcoin, he advises “shaving the cream off the top” (taking some profits) but “don’t dig into the principal capital.” This principle – never destroy the golden goose, only take its eggs – underlies how he views financial sustainability. Kim is not interested in flashy trading or quick flips; he prioritizes patience and conviction. He writes that he dismisses the importance of short-term profits, focusing instead on “long-term wealth accumulation through passive income and strategic, disciplined investments”, even when that runs “contrary to mainstream financial advice.” In practice, this has meant holding and accumulating assets he truly believes in (like Bitcoin or his own businesses), rather than diluting focus. Money, he notes, is like energy – “money is potential energy; when you actually put it to work… it becomes kinetic energy” . Thus, idle cash should be turned into active investments in ideas or ventures that generate value over time. Kim extends this physics metaphor to his love of Bitcoin: unspent Bitcoin represents stored energy (wealth), and he even jocularly remarks that if he holds more Bitcoin than someone else (and hasn’t sold it), “that means I am richer than you” .

In line with his frugality, Kim also rejects debt-fueled consumption and financing. He strongly advises against financing cars, expensive cameras, or other depreciating goods on credit . Instead, any extra funds should go into investments or saved for future opportunities. By avoiding liabilities and focusing on assets, Kim aims to build a resilient financial base. His concept of “financial independence” isn’t about retiring in the traditional sense, but about having enough capital working for you that you’re free from financial worry. In his blog he has even declared “Retirement is dead” – suggesting that rather than aspire to stop working in old age, one should strive to integrate work with passion and secure enough wealth to live how one wishes at every stage of life. In Kim’s case, wealth isn’t for hoarding or splurging, but for empowering the life you want: “The purpose of money is that you earn it, you invest it, you spend it… to continue the cycle all over again indefinitely.” In other words, money should continuously circulate into ventures and experiences that enrich you, perpetuating a virtuous cycle of creation and growth.

Conclusion

Eric Kim’s philosophy of capital can be summarized as freedom through financial discipline. He champions a life strategy of spend little, create often, and invest for the long term. By minimizing needs and avoiding debt, Kim believes one can accumulate capital that unlocks genuine freedom – the freedom to say no to uninspiring work and yes to one’s creative calling. Capital, in his view, is inseparable from creativity and fulfillment: it is the fuel that allows an independent, artistic life, but it must be handled wisely. This means treating money as a means to greater ends (not an end itself), guarding it carefully, and deploying it into projects and assets that reflect one’s values. “Wealth [is] a mental thing,” Kim writes, emphasizing that being truly rich is as much about mindset as money . Ultimately, Eric Kim promotes a lifestyle where money works for you, not the other way around – where having enough capital “in the bank” buys you the time, creative freedom, and peace of mind to live life on your own terms . His mix of ancient wisdom (like Diogenes and Publilius Syrus) and modern practice (like Bitcoin investing and open-source creation) culminates in a singular message: financial freedom is the key to personal freedom, and both are attainable through intentional living, relentless creativity, and respect for the power of capital.
