Even among the many monster episodes of Iron Culture, today’s episode truly stands out. First, the MASS crew discusses this new era of Iron Culture and lets the cult know what they can expect as the show pushes forward and climbs to new heights. After that, the crew has an insightful discussion about the science of satellite cells – what they are, when they might (or might not) matter, and how they intersect with many hypertrophy-related topics, such as sex differences, aging, muscle damage, and factors that limit long-term muscle growth.
The MASS crew records Iron Culture LIVE on YouTube, every Monday night at 7pm eastern time. Be sure to join us for a future episode and say hello in the live chat!
