Few clinical measurements are as quick, cheap and informative as grip strength. You hold a small device, squeeze as hard as you can for a few seconds, and read a number. Yet that number tracks closely with strength throughout the body, and with how people fare as they age.
What the research shows

In the Prospective Urban Rural Epidemiology (PURE) study, which followed nearly 140,000 adults across 17 countries, each 5 kg lower grip strength was associated with about a 16% higher risk of death from any cause. Grip predicted cardiovascular death more strongly than systolic blood pressure did.1
These are associations, not proof that squeezing harder makes you live longer. Grip is best understood as a window onto overall muscle health, which in turn reflects activity, nutrition, illness and age.
Thresholds clinicians use

The European consensus on sarcopenia uses a grip below 27 kg in men and 16 kg in women to flag low muscle strength.2 The US FNIH project also looked at grip relative to body mass index, because a heavier body needs more strength to move it.3 That relative measure matters for sarcopenic obesity, where low strength is hidden inside a larger frame.

Hand grippers can raise grip itself, but the goal is whole-body strength. Resistance training for the major muscle groups two or more days a week, enough protein, and staying active every day are what move the underlying picture. Grip then becomes a convenient way to check progress.
Try it yourself. Record your grip strength and save it to follow your trend.
