In this episode of "Office Hours Live," Dr. Eric Trexler and Dr. Mike Zourdos delve into a wide range of topics related to bodybuilding, strength training, and sports science. After a brief discussion about college football, they focus on the timing and planning of bulking and cutting phases, emphasizing the importance of long-term, intentional approaches rather than frequent switches back-and-forth. After that they address various listener questions, covering subjects such as fiber intake limits, optimal rest intervals between sets, training volume manipulation, the relationship between volume and muscle growth, and strategies for weight loss without calorie tracking. The conversation also explores muscle fiber type shifts in response to different training stimuli, the potential for new breakthrough supplements, and considerations for those using semaglutide for weight loss. Dr. Zourdos introduces the concept of the "cost" associated with various time-efficient training strategies, discussing their impact on fatigue and recovery. The episode concludes with an engaging discussion on elite marathon performances and predictions for future records.
