We have an exciting announcement at Iron Culture, we are combining forces with MASS, Monthly Applications in Strength Sport to bring you regular “MASScast” episodes where we will be joined by one or more of the expert MASS reviewers to talk science. In this inaugural MASScast episode we’re joined by Dr. Eric Trexler to discuss surprising recent data that suggests basal metabolic rates have been decreasing at the population level over recent decades. Is this true? And if so, what’s causing it? In addition, we discuss the continuing confusion regarding high versus low-carb diets. Where is the cut-off for being high or low carb, and when is each a good or bad approach? Listen in to learn what the latest data indicates and how to apply it!

In this episode, we discuss two topics, when and how to address fringe topics in the fitness space and the growing data in support of long muscle length partials for hypertrophy. In the former discussion, we discuss how science communicators are often in a difficult position when addressing such fringe ideas. When these beliefs are believed by small segments of the population - especially if they are potentially harmful - simply addressing them can potentially give them more legitimacy if not done right. Then we dive into “lengthened partials”, which only a couple of years ago would have been lumped in with the more common short muscle length partials you roll your eyes at in the gym all the time (think half squats). While formerly a fringe idea, the data continues to elucidate that this approach may have merit for hypertrophy. 00:00 Reviewing reviews: addressing the carnivore diet.

In this episode, we’re joined by Mitchell Hooper fresh off his 2023 World’s Strongest Man (WSM) win. In addition to winning the 2023 WSM, he also won the 2023 Arnold Strongman Classic. He is among only four competitors to have won these two titles in the same year, and he is the youngest ever to do so, now sitting among living legends Brian Shaw, Žydrūnas Savickas, and Hafþór Júlíus Björnsson. In our conversation we discuss how Mitchell seemingly burst onto the scene out of nowhere, what it’s like competing in the WSM, his future, the future of strongman and the WSM in the modern era, and his perspective on being a champion and ambassador. Finally, we discuss how Mitchell’s education - having a master's degree in exercise physiology - influenced his training approach, which is surprisingly simple and seemingly non-traditional. As a relative newcomer to the sport, his approach hasn’t been influenced by typical strongman “dogma” and thus, his entrance onto the scene may have a revolutionary impact on how athletes train for strongman and strongwoman in the modern era.

You’ve probably heard of the famous, ancient lifting stones in Iceland and Scotland, some of which are even replicated and used in strongman competitions. But did you know that over 20 stones (and still counting) have been uncovered just in the last few years in Ireland, many of them heavier than the stones in Iceland and Scotland, by primarily one man? That man, Kettlebell Sport World Champion and amateur historian David Keohan (affectionately called “Indiana Stones”) joins us in this episode to discuss the incredible stories of how these stones were unearthed. You’ll hear about these ancient stones and their rich cultural significance and connections to mythology. While we often think of history as something in the past, when you tune in you’ll learn how some history is still being uncovered in real time! 00:00 Paying respects to a ⭐ ⭐ ⭐ ⭐ ⭐ review 3:20 Introducing David Keohan and lifting stones in Ireland Rogue Fitness documentaries Stoneland: https://www.youtube.com/watch?v=MhQlNwxn5oo Fullsterkur: https://www.youtube.com/watch?v=79Tcsg2Yac8 Levantadores: https://www.youtube.com/watch?v=vck32S27RmM 19:53 Researching the stones 32:18 The process of finding the stones and recording the findings 37:24 Promoting the (oral) history of the stones 52:26 Significance of the symbolism of the stones  1:05:45 Closing out and where to find David  Instagram: @_indiana_stones_ https://www.instagram.com/_indiana_stones_/

Coaches in the evidence-based community are often up to date with the latest in periodization and sports nutrition, but many are not even aware that there is a tremendous amount of research on coaching itself. What makes a good coach? Hint: it’s not simply being up to date with science, as that would mean that every coach prior to the modern era is a bad coach. So, what is it to be a good coach? As the title implies, it’s not about you, it’s about being athlete-centered. But what does that mean? Join in to find out!
