Scientists claim grip strength and chair rises can predict lifespan with surprising accuracy

Two simple tests may reveal your future health

A new study suggests that older women’s muscle strength—measured by grip strength and how easily they can stand from a chair—can strongly predict longevity. Researchers found lower mortality risk among participants with greater strength, even after accounting for physical activity and other health factors. The findings point to practical, at-home screening that may help flag risk earlier than traditional measures.
