what it claims

Your grip strength is a simple and powerful indicator for estimating your level of physical vitality and predicting your life expectancy.

The assertion that grip strength can predict life expectancy rests on very solid scientific foundations.

The assertion that grip strength can predict life expectancy rests on very solid scientific foundations. A vast prospective observational study called PURE, published in The Lancet by researcher Darryl Leong, showed that a 5 kg decrease in this strength is associated with a 16% increase in the risk of death from all causes. Furthermore, an umbrella meta-analysis of observational studies confirms that hand strength is an excellent reflection of general vitality and physical aging. However, an important nuance must be noted: this strength is a simple indicator, not a direct cause of longevity. Training solely by squeezing a spring-loaded tool will not prolong your life if the rest of your body weakens. To reap the benefits of this vitality, one must prioritize physical strengthening of the entire body rather than focusing solely on the strength of your hands.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: all-cause and cardiovascular mortality per 5-kg lower grip strength — PURE: all-cause mortality HR 1.16 (95% CI 1.13-1.20) per 5-kg lower grip (n=139,691); UK Biobank: HR ~1.16-1.20 all-cause, plus higher CVD/respiratory/cancer mortality (n=502,293)
Measured on: community-dwelling adults across many countries (ages ~35-70)

This is an association, not proof that grip itself causes longer life; grip reflects overall muscle strength and health. Training grip in isolation is not the point, whole-body strength is.
