In this episode of MASS Office Hours Live, Dr. Eric Trexler and Dr. Mike Zourdos kick off the show by discussing a recent controversial Instagram post about a retracted cold bath/cold shower study, emphasizing the importance of understanding the hierarchy of evidence and the challenges of effectively communicating retractions to the public. The hosts then share some of their past fitness and nutrition recommendations they now wish they could retract. The episode then transitions into a rapid-fire Q&A segment, addressing a wide range of listener questions. Topics covered include the optimal resistance training frequency for muscle growth and whether it should differ between bulking and cutting phases, the potential benefits of hydrolyzed whey protein compared to regular whey, the effects of Tylenol on performance and gains, the superiority of training to failure versus leaving reps in reserve for hypertrophy, a potential link between appetite suppression and longer rest periods during a calorie deficit, how to train for maximum power production in athletic contexts, and much more. Throughout the discussion, Trexler and Zourdos provide evidence-based insights and practical recommendations to help listeners navigate these common fitness and nutrition questions.You can download the MASS time-efficient training guide here:https://massresearchreview.comThe MASS crew goes live for Office Hours every Wednesday night at 7pm eastern time.
