In this “Ask Me Anything” (AMA) episode, Peter and Bob discuss the longevity benefits from greater cardiorespiratory fitness (CRF) and greater muscle mass and strength. Conversely, they dive deep into the literature showing a rapid increase in morbidity and mortality risk as fitness levels decline with age. They also try to tease out the relative contributions of CRF, muscle mass, and strength. Additionally, they discuss the impact of fasting on muscle mass, the potential tradeoffs to consider, and finish by discussing why it’s critical to maximize your fitness level.
