Muscle strength can be important for healthspan.

Muscular strength is independently associated with lower all-cause mortality risk even after adjusting for cardiorespiratory fitness and other factors such as age, body fat, smoking, and alcohol intake.

The higher mortality risk associated with decreased levels of muscular strength is similar to well-established risk factors for early death such as obesity, hypertension or smoking. Maintaining muscle mass and strength through various forms of strength training may be a modifiable risk factor for all-cause mortality.
