Iron Culture presented by MASS
Iron Culture was started by Eric Helms and Omar Isuf as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. It's now hosted by Eric Helms and Eric Trexler, who repeatedly beg Omar to return as a guest.
Iron Culture focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community.
Iron Culture is proudly presented by the MASS Research Review.

Ep. 134 - You Don’t Understand Genetic Limits
Natty limits, genetic potential, everyone talks about these concepts, but most people truly get it wrong. You’ve heard the tropes, “you reach 80% of your muscular potential in your first X years of effective training.” It sounds great in theory, but it is the exception rather than the rule when it plays out this way in the real world. How often do people start off with effective training? How does regular dieting, either for competition or for the likes impact this timeline? What about injuries, time off, school, kids? How about simply figuring out what works best for you after years of being unable to? Despite the “rule” being so volatile and highly variable due to these factors (and others), it’s surprisingly common to hear people use this “logic” to justify anything from slacking off on training, to hopping on anabolics, to even supposedly identifying fake natty's. Join us in this episode as we talk about the not-so-linear timeline of approaching the asymptote that is your potential.

Ep. 133 - The Shady History of Supplements (ft. Dr. Conor Heffernan)
Dr. Conor Heffernan, the Strength historian, and Ben Esgro, the dual-masters degreed sports nutrition/pharmaceutical chemistry formulation artiste are both back on Iron Culture for this monster episode on the history of the supplement industry. Learn what it was like in the days of Sandow’s cocoa and how at one point in America’s history, every lifter had a little Bob Hoffman in them…literally. Contrast and compare that history with the contemporary experiences Ben has had in the supplement industry for over a decade, and you’ll see what has and hasn’t changed in this insider’s view into the world of powder and pills.

Ep. 132 - Where Does Broscience Come From?
This episode will hit your ears like a sonic boom, changing your perspective on “broscience” in a flash. Where do lifting myths come from? Locker room convos between Chad Broseph and Chance Halfsquat? Sometimes. But more often than not, the myths of today were the scientific truths of yesterday. So how do we pursue truth when faced with the reality that some of what we think we know today is incorrect? Well, we must avoid over concluding on the limited evidence we have, seeking to evaluate not only what that evidence can tell us, but also what it can’t. Tune into this episode to learn more about this process.

Ep. 131- Training To Failure (What the Science Actually Says)
If you don’t train to failure, you’ll be a failure. It not only sounds good, but it also appeals to the hardcore inner masochist in every serious lifter that’s just waiting to strike in the comments section. But, is the saying true? In this episode, we’re joined by Zac Robinson from Data Driven Strength to find out. He’s a powerlifting coach who did his master's degree specifically on the effects of training to and short of failure on hypertrophy and strength with Dr. Mike Zourdos at Florida Atlantic University. You’ll learn that there are in fact pros and cons to training to failure, and there are times, exercises, goals, and situations that may warrant training to failure, or *GASP*….quite far from it! So as you tune in, prepare your inner hardcore masochist for jimmy-rustling, feather-ruffling, and maybe even some gear-grinding.

Ep. 130 - We Were WRONG
The cornerstone of scientific thinking is updating your beliefs based on the available evidence. Unfortunately this conflicts with the cornerstone of being a cult of personality guru leader, which requires doubling down and never admitting fault or when you’re wrong. In this episode we break the fourth wall, coming down off the top of the pyramid to have a non-canon discussion about all the times we’ve changed our minds and updated our beliefs. Not only is each instance an opportunity to discuss how specific evidence has changed over time and the nuances of a given topic, but the entire episode serves as a meta-discussion on continually learning. Make sure to tune into this one to hear all the times we’ve been wrong, but then quickly forget about it because Omar and I are never wrong.

Ep. 126 - Competing At The Highest Level In Powerlifting: An Inside Look (ft. Bryce Lewis and Ashton Rouska)
Does being a competitor require a competitive mindset? In some sports, yes. But in powerlifting, you arguably could just focus on yourself, progressing, and show up on game day ignorant to your competition, put up the best total you can, and see where you place. Indeed, some world-class competitors do just that. With that said, athletes are human. Some thrive off a competitive mindset and feel it drives them to athletic heights they couldn’t achieve on their own. Others, however, feel like this provides pressure, self-judgment, and saps the joy from powerlifting without adding any benefit. Ultimately there isn’t a right or wrong answer. Each person has to figure out what is most facilitative to improved performance for them individually. On this episode we’re joined by Bryce Lewis and Ashton Rouska, the top two 105kg IPF lifters in the world currently who’ve battled it out at USAPL nationals twice now, with Bryce coming away as the 2019 National champ and Ashton the 2021 National champ. They have a candid conversation where you’ll learn how they each approach competition, what they’ve learned, and how it can apply to you.
