How to use it
Grip strength, VO2max and leg power predict a long life partly because they're easy to measure. If one of yours is low, train it directly: that's where the big gain is. Once you're good, pushing it to elite matters less than being well-rounded: strength, power, speed, balance, mobility and hours of easy endurance.
How sure we are
P Evidence: promising. Good studies, but small or few. Use it and keep checking.
E Evidence: built from practice. What works for coaches and practitioners. Labelled that way.

In 139,691 adults across 17 countries, every 5 kg less grip strength meant about 16% higher risk of death over 4 years (Leong et al. 2015, Lancet, cohort, 🟡) · "proxies, not targets": Andy Galpin (🟠).
