90 minutes of lifting a week cuts the risk of early death by 13%

Just a couple of hours of strength training each week could have surprisingly powerful effects on longevity. People who lifted weights for around 90 to 120 minutes weekly showed a 13% lower risk of dying early.

The finding supports the view that resistance training makes an independent contribution alongside the cardiovascular activity that has long dominated exercise guidance.

The relatively low time threshold is notable for how achievable the recommendation is: two to three short sessions a week are enough to meet the stated range.

MHA Analysis

The practical value here is the low threshold rather than the size of the effect: 90 minutes a week removes the time argument most people give for stopping. Exercise guidance has centred on cardiovascular activity for decades; resistance training making an independent contribution reframes that advice, particularly past 40 when loss of muscle mass accelerates. With the caveat that a single observational finding does not establish causation, the evidence bar is naturally lower for an intervention this cheap and this low-risk.
