# Grip strength

Grip strength is the maximal force you generate when you squeeze a device called a dynamometer. It is a cheap, simple proxy for your whole-body muscular function. In the 17-country PURE cohort (Leong et al., Lancet 2015; about 140,000 adults), each 5 kg drop in grip strength predicted roughly a 16% higher all-cause death risk. That actually beat systolic blood pressure as a mortality predictor. Grip strength correlates with your neuromuscular health, nutritional status, and recovery capacity. That makes it one of the most validated biomarkers of biological aging.
