Mark Hyman on Being Sedentary: warns against

On CBS Mornings (September 2026), Hyman warned: “The biggest risk for your health is the couch,” framing inactivity as a driver of faster aging. The paired recommendation — strength training, HIIT, and “exercise snacks” — is covered in its own position page.

His stated reasoning is that sedentary behavior accelerates the biological aging processes he organizes his longevity work around, making movement frequency as important as structured exercise. (Hyman’s position; not this site’s medical advice.)
