Half an hour of muscle strengthening activity such as lifting weights, push-ups or heavy gardening each week could help reduce the risk of dying from any cause by as much as a fifth, according to a new global analysis of studies conducted over three decades.

Health guidelines recommend muscle strengthening activities, primarily because of the benefits for musculoskeletal health. Previous research has indicated a link to a lower risk of death, but until now experts did not know what the optimal “dose” might be.
