In this “Ask Me Anything” (AMA) episode, Peter dives deep into the question of whether there is such a thing as “too much exercise.” He explores the theoretical “J-curve” relationship between exercise and longevity, whereby mortality risk declines with increasing activity levels only to see an uptick above a certain exercise volume threshold. While Peter maintains that exercise is perhaps the single most important tool we have to live longer and live better, he explains the challenges involved in identifying an optimal dose. He takes a hard look at studies—many of which have contradictory results—to highlight major limitations in methodology and how readers could be misled. Additionally, he discusses the rare, but real, risks associated with extreme levels of physical activity and concludes by weighing the benefits against the risks of exercise.
