Key Moments

TL;DR

Discusses supplement controversies (Turkesterone), neglected muscles, and carbohydrate overfeeding.

Key Insights

1

Turkesterone and beta-ecdysterone supplements may be aggressively underdosed or contain inaccurate ingredients.

2

Neglected muscle groups include scapular protractors, hip flexors, and hip ad/abductors, which contribute significantly to overall muscle mass and can impact physique.

3

Carbohydrate overfeeding is not a 'cheat code' for bulking; while de novo lipogenesis is less efficient than fat storage, it can occur, especially with extreme carb intake and fat restriction.

4

The article 'The Most Commonly Neglected Movements and Muscles' by Cameron Gill offers insights into training overlooked muscle groups.

5

Science by press release can lead to misinterpretations, as seen with a news article suggesting running ages men, contradicting broader research.

6

While de novo lipogenesis from carbs is inefficient, it offers a slight buffer against overeating during bulking compared to fat.

ATHLETIC ACHIEVEMENTS AND PODCAST CORRECTIONS

The episode opens with a recap of recent powerlifting competitions, highlighting impressive records in squats, bench presses, deadlifts, and total lifts across various weight classes by athletes like Jonathan Garcia, Russell Ori, Jamar Royster, Elias Buchalam, Aseam Inohoro, Eddie Berglund, Bryce Lewis, and David Wilson. The hosts also address 'Wronger By Science' corrections from the previous episode regarding the phrenic nerve and a humorous acknowledgment of a Mitch Hedberg joke reference.

PHYTOECDYSTEROID SUPPLEMENT CONTROVERSY

The discussion delves into the controversy surrounding phytoecdysteroid supplements like beta-ecdysterone and turkesterone. Historically, beta-ecdysterone hype fizzled due to limited human data and findings of severe underdosing in supplements. Turkesterone has faced similar hype, but recent independent testing suggests many products contain negligible amounts of the active ingredient, often containing more beta-ecdysterone instead, raising questions about market quality and supplier integrity.

IDENTIFYING AND TARGETING NEGLECTED MUSCLES

An article by Cameron Gill, 'The Most Commonly Neglected Movements and Muscles,' is highlighted. It identifies neglected muscle groups as scapular protractors (pec minor, serratus anterior), the hip flexor group, and hip ad/abductors. These groups represent significant muscle volume, comparable to major muscles like the lats or glutes, and their development can contribute to overall physique and potentially aid in long-term training longevity by addressing imbalances.

VISUAL IMPACT OF TRAINING NEGLECTED MUSCLES

The visual impact of training neglected muscles is compared to developing the brachialis, which pushes the bicep further from the humerus, making the arm appear larger. Similarly, improved hip flexor development can make quads appear more developed, and enhanced pec minor development can contribute to better upper chest aesthetics. These deeper or less superficial muscles contribute to a more complete and developed physique when trained effectively.

CARBOHYDRATE OVERFEEDING DURING BULKING

The podcast addresses carbohydrate overfeeding during bulking, debunking the idea that it's a 'cheat code.' While direct conversion of excess carbs to fat (de novo lipogenesis) is inefficient and less likely when fat is also consumed, it can occur under conditions of extreme carb overfeeding and severe fat restriction. The primary fates of excess carbs include glycogen storage and oxidation for energy, with some energy expenditure due to the thermic effect of feeding.

NUANCES OF DE NOVO LIPOGENESIS AND BULKING STRATEGIES

The inefficiency of de novo lipogenesis from carbohydrates is highlighted; while it leads to some energy wastage, making high-carb overfeeding slightly less conducive to fat gain than high-fat overfeeding at equivalent calories, this difference is marginal in practical terms. The article emphasizes that during bulking, focusing on sufficient protein intake, effective hypertrophy training, and an appropriate calorie surplus is paramount, rather than over-manipulating macronutrient ratios for perceived metabolic advantages. A controversial abstract suggesting muscle gain and fat loss on extreme low-fat diets is discussed but largely dismissed due to lack of replication and potential methodological flaws.

SCIENCE BY PRESS RELEASE AND MEDIA MISREPRESENTATION

The segment on 'Science by Press Release' criticizes how preliminary research findings are often sensationalized and misrepresented in media. An example is given where a press release about a study showing stiffer aortas in male runners compared to female runners, presented at a conference, led to headlines claiming running ages men. This bypasses crucial context, such as the overall benefits of running for cardiovascular health, reduced mortality, and lower blood pressure, which contradict the sensationalized narrative.

THE IMPLICATIONS OF RUNNING RESEARCH

The research discussed suggests that while male runners might exhibit increased aortic stiffness, this does not translate to negative health outcomes. Extensive meta-analyses show that running is associated with lower all-cause, cardiovascular, and cancer mortality, reduced stroke risk, and lower blood pressure in both men and women. This highlights the danger of drawing definitive conclusions from preliminary findings and the need for journalistic integrity and background research to avoid public misinformation.

MUSICAL RECOMMENDATIONS FOR TRAINING

Concluding the episode, the hosts offer musical recommendations for training, shifting from their usual eclectic tastes to heavier genres. Tool and Mastodon are suggested for their complexity, musicianship, and slightly more conventional compatibility with resistance training. The effectiveness of aggressive music for catharsis and stress release is noted, contrasting personal experiences with intense concert environments.

Addressing Neglected Muscles

Practical takeaways from this episode

Do This

Incorporate exercises that target scapular protractors (pec minor, serratus anterior) for better upper chest development.
Include training for hip flexors, as their total muscle volume can exceed that of the gluteus maximus.
Pay attention to the hip adductor group, which is often neglected.
Consider training deep muscles like the brachialis, which can enhance the visual size of the biceps.
Be aware that developing these often-neglected muscles can contribute to overall aesthetic development and potentially improve movement longevity.

Avoid This

Do not solely focus on major compound lifts (squats, presses, hinges) as they may neglect certain muscle groups.
Avoid assuming that visible muscles are the only ones that matter for physique or function.
Do not ignore persistent hip or back discomfort; neglected musculature might be a contributing factor.

Common Questions

Phytoecdysteroids are compounds produced by plants as defense mechanisms. They've gained popularity in fitness due to research suggesting Turkesterone, in particular, may have anabolic effects, although robust human data is limited.
