A recent study from Penn State College of Medicine states that All-cause mortality may be significantly reduced through the identification of and engagement in guideline-concordant ST interventions by older adults.
What does this mean in plain English? In the study they found the chances of all causes of mortality dropped by around 46% in those that strength trained.
This means that lifting weights in effect, may make you living longer.
Not such a meathead now, hey?
