Combine enough truisms that lack precision and nuance and people get confused. This is exactly what happens in typical discussions of hypertrophy training while dieting. When a deficit is framed as a "state" rather than the cumulative effects of long term (body comp) and short term (acute energy balance) energy availability, and tropes like "volume is the primary driver of hypertrophy", "intensity is more important than volume" and "dieting is catabolic" are stated without nuance, logic disconne...

The Carnivore Diet has exploded in popularity over the last several years thanks in large part to some very bold claims made by leading advocates. From the harmfulness of plants to the uselessness of fiber, these assertions are certainly bold. In this sizzling episode, Iron Culture hosts Omar Isuf and Eric Trexler investigate the validity of these claims, thoroughly examining and dispelling many incorrect beliefs commonly parroted by some aspects of the community. Surely this will be the least c...

EMG studies, they're the classic "evidence-based" tool to "Um actually" all the bros about what the perfect exercises they should have chosen for every muscle group. Or are they? Today we're joined by returning guest, Ph.D. candidate Andrew Vigotsky, who's published some of the most influential papers on the limitations and the best practice guidance for EMG research. In this episode, we learn what EMG data can and can't tell us, what types of evidence we should rely on to inform exercise select...

As you all know, we at Iron Culture have succeeded in becoming lifting cult leaders, which basically means we've failed at our previous attempts at having respectable jobs (sorry mom). However, the good news is that we are experts on failure because of this. In this episode we do a deep dive on failure in resistance training, building on prior episodes to help you understand why this seemingly straightforward concept is so murky, and why there is so much disagreement in the literature on proximi...

We're back with another completely legit Q&A episode from 100% real listeners. Once again, thank you, Tommy, Tanya, and Tyrone. Omar was the highlight of this one, as the second question was specifically about using "questionable" marketing tactics, but in the name of good, to distribute evidence-based information, and whether doing so was ultimately helping people, or discouraging critical thinking. Sandwiching Omar's fantastic answer, Eric addressed two science-based questions in this epis...

Recently, the first systematic review and meta-analysis on the effect of autoregulation on strength and hypertrophy was published. In this episode we explore why this publication almost sent Eric into a proverbial dark cave without a pen light, never to return, and what realizations helped him find his way out. In this episode, we discuss that the promise of autoregulation is really Individualization. With that discovery, we explore how it succeeds, and fails, at least in its current limited for...

The hype around Vitamin D supplementation has waxed and waned over the years in the lifting community, but has overall, landed in a place where it's more or less universally seen as a positive supplement. But what is the state of the data? What can you expect as a lifter out of vitamin D supplementation? How do you measure vitamin D status, how reliable are these measures, and should we even be measuring it? The answer probably differs at the population and individual levels. We're joined by Dr....

Turkesterone and ecdysterone have garnered a lot a of interest as of late, and a number of notable folks in the evidence based community have done a great job pointing out the lack of evidence supporting their efficacy. For newer lifters, you might not be aware, but this isn't the first time these compounds have been hyped up beyond the evidence. Is this hope and hype founded? In this episode we're joined by Ben Esgro, who uses his pharmacological knowledge to explain that it probably isn't. Joi...

Exercise selection, a multi-layered piece of cake that you don't have to eat all of to benefit from, but really, who eats just part of a slice of cake (weirdo)? For hypertrophy, it can be as simple as having a few compound exercises for each major muscle group, a few isolation exercises to round them, smaller muscle groups out, and training through a full ROM. But, what about the folks who tell you compounds are all you need? And what about all those bodybuilders who swear by (certain types) of ...

Watch the Episode Here: https://youtu.be/99e5iFWZwEQ Deloads, sometimes called unloads, light weeks, or simply incorporated as phases of a periodized plan, are frequently discussed in the evidence-based community, but they actually have very little direct research behind them. If that's the case, why are these phases universally used? What principles are deloads based on? What sectors of research do we use to indirectly inform their structure? And most importantly, what options do you have for d...

In this episode of Iron Culture, we're joined by Alex Tilinca. Alex is a young competitive physique athlete with an already impressive amateur career thus far, seeking to get nationally qualified this year and hopefully compete at the national level in the NPC in the Classic Physique division. He's also a prep coach at Scooby Prep, the well-known prep coaching company started and led by Jason Theobald. What makes Alex's journey unique, is that he was born female, and is the first transgender man...

In this episode of Iron Culture, we do a deep dive on the topic of pre-workout carbohydrate intake. While the data on endurance training is relatively consistent in showing a beneficial effect on performance, it's more complex for resistance training. For strength and power, what you eat prior to training is probably less important, but when assessing the ability to perform volume, the data indicate that eating prior to training can in some contexts make a difference. This then leads to a discus...

We're kicking off 2022 by listening to the people. We, your humble cult leaders, are benevolent theocratic overlords, who want your voice to be heard (so long as you say and ask things that we approve of beforehand). That's right, we're back with another question and answer episode! In this episode, we discuss the differences between effort and exertion, what the latest data on frequency suggests, and what the limitations of the extant frequency data are, and finally, we discuss the role and imp...

As it's said, truth is stranger than fiction. On Iron Culture we've pointed out multiple fantastical, claims backed by pseudoscience that were just gimmicks designed to make you buy something. But sometimes, things that sound gimmicky are actually legit. In this episode, we cover a number of them, like the surprising effects of visualization (AKA motor imagery) training on strength, the effects of compression garments on recovery, and also the positive and negative effects of cold therapy....

Can you believe it's been nearly 3 years of running the cult? By this point, most people in our shoes would have had their final Kool-Aid party, ran out of followers after inaccurately predicting the apocalypse too many times, or simply had the law catch up with them after too much credit card fraud and polygamy. But nay! We still stand (err sit) before you, preaching the gospel THEY don't want you to hear. That's right, this pirate radio station isn't going anywhere (at least until one of the b...

We get questions all the time like "is squatting more than twice a week overtraining?" Or, "how much volume is overtraining?" But what is the actual scientific definition of overtraining, do lifters actually experience it, and what does overtraining result in? In this episode we do a deep dive on the topic of insufficient recovery, some of which falls under the umbrella of overtraining, and some of which falls under the umbrella of under-eating. Ultimately, by the end of this episode you'll walk...

Returning guests Dr. Gabrielle Fundaro and Dr. Ben House discuss how the divide in the nutrition community spurred by the "diet" and "anti-diet" debates can potentially lead to inaction and subsequent unaddressed problems. When there is a passionate debate across a moral divide, data often goes by the wayside. This occurs when obesity-focused practitioners and researchers don't acknowledge pathways to improved health other than weight loss, or the potential harm from weight loss attempts which a...

Another duo episode? Some say it's because we've burned every bridge with every guest we've ever had on, but the truth is we just can't get enough of each other. In this episode we discuss how mental fatigue can impact training, based on some interesting research on the topic, and how being distracted in certain ways can potentially help skill acquisition. After this brief research review, we dive into the main course, which is to discuss the following questions: when is it the right move to tak...

Hard work is undeniably an essential element of success in the iron game and life. Yet, while that is true, just like telling someone who is depressed to "cheer up", telling someone struggling with their progress to "try harder" doesn't help. Despite that, so much of our signaling on social media, our shared community values, and our identities as lifters come down to expressing, celebrating, and worshipping that exact sentiment. In this episode, we explore why this happens, and the rare cases w...
