In this crossover episode of Iron Culture and MASS Office Hours, Dr. Trexler is joined by special guest Josh Pelland, a coach for Data Driven and a PhD candidate at Florida Atlantic University, to discuss Pelland's recent meta-analysis which investigates the effects of training volume and frequency on hypertrophy and strength outcomes. These data have created a lot of stir in the evidence based community as very high volumes seem to be associated with hypertrophy without a definitive plateau. But as you can expect, there's much more to the story. The analysis synthesizes data from numerous studies and quantifies dose-response relationships by which higher training volumes and/or frequencies may lead to greater strength and muscle gains in response to resistance training. In a thorough discussion of the paper, Pelland discusses nuances, such as the point of diminishing returns where further volume or frequency may yield less significant gains, and highlights how individual factors like training experience and muscle group-specific responses affect outcomes. Practical recommendations include tailoring volume to individual needs, utilizing periodization and volume cycling to maximize adaptations, and addressing common pitfalls such as overtraining. Further, in this live episode audience questions drive deeper exploration into the practical implications of the findings and strategies for optimizing training programs based on current evidence.

The classic Iron Culture duo hosts this week's episode to discuss exercise variety. How have the views on this topic changed over the years and why? First, we need to understand how and when bodybuilding separated from strength sport, equipment availability changes over time, and how these factors impacted the perception of exercise variety. From the Weider “Muscle Confusion Principle” to motor learning concepts like varied practice, there's been discussion of exercise variety in both the trenches and research for decades. In the modern era, concepts like regional hypertrophy and more nuanced understanding of functional anatomy have become more common and widely understood and accepted, leading to the acceptance that at least for hypertrophy, higher exercise variety is necessary to maximise the development of specific muscle groups. But, as they say, a little knowledge is a dangerous thing. Many without a sufficiently complete understanding of anatomy make errors when it comes to claims about exercise selection and variety for bodybuilding. So listen in on this episode as we talk through the history, science and culture of exercise variety for hypertrophy, as well as strength!

Back in the day, most lifters were all-in on the “Cartesian” or “biomedical” model of pain, which posits that pain is a simple, reliable indicator of damaged tissue causing nociceptors to send a “pain signal” to the brain. Nowadays, the “biopsychosocial” and “fear-avoidance” models are all the rage in the evidence-based lifter circles. These models are a major upgrade, but there are still some pervasive misunderstandings and misinterpretations of these models in the lifting world.

Powerlifters use techniques to milk every last kilo out of their bench press, including wide grips, tightly wound wrist wraps, leg drive, and – the most hated technique in the comment section – an arched-back to reduce the range of motion. Indeed, it can get so heated in the comments it likely even influenced an IPF rule change last year. But how many kilos does an arch really give you? How many bench pressers did this rule change impact, and was there really a need for the rule changes? Further, why do we apply a different standard for what is considered “cheating” to different lifts or athletic movements, like technical manipulation in high jump, or weightlifting? In this episode you'll get the full complement of the Iron Culture themes: we discuss the current culture around the IPF rule change and contemporary perspectives on arched bench press, the history of the clean and press in Olympic weightlifting up to 1972 which has some very interesting parallels, and finally a recently published study which attempted to quantify how much an arch increases bench press 1RM. 00:00 Intro to an episode about when Powerlifting was Powerlifting 03:33 The good old IPF and their regulations 08:40 The bench press rule change 15:23 The motivating factor for the rule change 20:01 Trexler's technique and thoughts on the rules Barbend article: https://barbend.com/ipf-bench-press-rule-change-2023/ 26:22 The history of Olympic weightlifting and Powerlifting and the change in rules 38:39 The Fosbury flop and the perception of different movements and innovations 44:52 Athletes finding ways to maximise performances within rules  57:16 A recent study on arching in the bench press Bartolomei 2024 Flat-Back vs. Arched-Back Bench Press: Examining the Different Techniques Performed by Power Athletes https://pubmed.ncbi.nlm.nih.gov/38551927/ 1:05:38 The nature of the fragile ego and the final point on the perspective of the spectator

From what goes on in the lab itself, to the publication process, to dissemination, to eventual meta-analysis, the challenge of interpretation and communication of science, the optimistic promises of open science, and the increasing focus on replication, it's been a hopefully eye-opening and overall encouraging discussion. However, while the scientific method is inherently self-correcting, the apparatus of science is far from perfect and there is a big problem with its principle tool of correcting the peer-reviewed record: retraction.

Dr. Pak is back on Iron Culture for his third appearance! This time, he sat down with Omar and Dr. Helms for a meta-discussion on the challenges of science communication. How do you maintain credibility when you're using social media as a science communication tool? This challenge has changed, but it isn't new by any means. The “Sagan effect” describes the well-researched phenomenon by which the scientific community perceives other scientists who get more media exposure as less legitimate scientists - despite the fact that, on average, scientists more active in science communication typically publish slightly more often and with a higher impact than scientists less active in science communication. In modern times, however, the incentive structures are different, and many instances of expert creep, “selling out” and pseudoscience have been propagated on social media by some academics or members of the medical community. In this episode we discuss the challenges of attempting to communicate science without being criticized for doing so, how this has and hasn't changed over time, and the instances of gatekeeping which are ultimately counterproductive to increasing scientific literacy.

After their recent reconciliation, the Erics got together for this duo episode to bond over their mutual love of protein. But, dear listener, this might not be the home-cooked high-protein meal you hoped for. Dr. Trexler tackles the question of whether or not, GASP, protein restriction might extend lifespan! Then, to add insult to injury, the Erics dig into the question of whether or not plant-based protein sources could be superior to animal sources for improving healthy aging! Along the way, you'll also learn about the limitations of both epidemiological and mechanistic protein research, and how the two can complement each other to lead to more robust conclusions. So grab your pea protein shakes - or maybe your protein-free placebo - and tune in for another monster episode of Iron Culture.

As you know, Iron Culture reps the neutral to positive gang around these parts. While most new supplements released to the market don't pan out as effective, some do. So, if preliminary data supports the potential efficacy of a new supplement, why not try it out? The only potential downside of trying a new supplement is wasted money, right? Not so fast. In this episode the Erics duo explains why the typical supplement consumer is not accurately weighing the true potential cost of supplement investment. Unbelievably, some data indicates 10-30% of all supplements are contaminated - you heard that right. Could that be true? If so, why and how is this happening and what can you do about it?

In our third interview following the 2023 natural bodybuilding season, we sit down with another historic champion with a truly outlier series of performances. This time, Australian phenom Beccy Pateman joined the Erics on Iron Culture to discuss her season, which culminated not only in her winning her WNBF pro card in both Figure and Fit Body, but also winning the WNBF pro world fit body title. As we've discussed, for an athlete to turn pro in the WNBF and win a pro world title in the same season is incredibly rare. Further, the weekend prior to WNBF worlds, Beccy won the Professional Natual Olympia Figure title in the INBA/PNBA. Winning two world titles, relatively early in one's career, in two different federations, and in two different divisions nonetheless, is an even more incredible feat, which only a handful of athletes have ever done in the history of natural bodybuilding. Indeed, the athletes who have done so have, in most cases, gone on to become legends of natural bodybuilding. How did Beccy do it? What did it take for her to get to this point in her career and what is in store for her?

It's hard to explain to those who haven't competed what it is about bodybuilding that can grip people and transform them. The near-spiritual experiences that some physique athletes gain through prep and competition are something shared regardless of division, federation, natural, or enhanced. In this episode, we sit down with Dr. Mike Israetel, not to talk sports science like you're used to, but to talk about what lies at the heart of the sport. Mike has been pushing forward through multiple seasons in his attempt to become an IFBB pro bodybuilder, an incredibly challenging feat that requires tremendous sacrifice and drive. What fuels a journey like that? What does a competitor experience - highs and lows? What do they learn, and how do they change? You might be surprised as well, that despite the different paths Dr. Helms and Dr. Israetel took as competitors, that at the heart of their experience lie many similar threads.

This episode almost didn't happen. With Omar away, the Erics left to figure out how to do an episode of Iron Culture on their own, and nearly got stuck waiting forever for someone to say “Eric.” But, cooler heads prevailed and they found their way into a thoughtful, introspective, and nostalgic conversation. While both Trexler and Helms ended up taking very similar paths in life when you look at the outcome - competitive bodybuilders with PhDs in exercise-related fields who communicate science - their motivations and perspectives are actually quite unique. In this episode, you'll learn how someone can find themself competing in the wacky sport/art we call bodybuilding, and what that experience can become, in terms of a cathartic outlet, a personal identity, a career, or even a science experiment.
