What is the single best predictor of longevity from exercise?

VO₂ max. People in the top 25% of cardio fitness for their age have a fraction of the mortality risk of the bottom 25%.

Should older adults still lift weights?

Yes — resistance training is the single most effective way to preserve muscle mass, bone density, and independence with age.

Grip is a strong proxy for whole-body strength and predicts mortality independent of other factors. Train it directly.
