Mark Hyman on Strength Training and HIIT: recommends

On CBS Mornings (September 17, 2026), Hyman framed strength training and high-intensity interval training as his two priority exercise types for longevity. For people who won’t do formal workouts, he suggested short “exercise snacks” scattered through the day.

His stated reasoning is that muscle and conditioning are longevity levers — the same appearance carried his paired warning that inactivity is the biggest everyday health risk. The advice connects to his “hallmarks of aging” framework, where he claims lifestyle inputs can influence biological aging pathways. (Hyman’s position; not this site’s medical advice.)
