The Claim
A J-shaped nonlinear association exists between weekly strength training volume and all-cause mortality in older women, with the lowest mortality risk observed at approximately 82 minutes per week and increased risk at volumes above 146 minutes per week.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older women, weekly strength training of about 82 minutes is linked to the lowest risk of death from any cause; training less than this or more than 146 minutes per week is associated with higher risk.

Doing a moderate amount of strength training builds muscle, which helps the body use sugar and fat better, lowers inflammation, and keeps blood vessels healthy. This reduces the chance of heart disease and death. But doing too much strength training causes very high blood pressure spikes and overactivates the stress system, which stiffens arteries over time and raises the risk of heart problems and death.
What the research says
1 studyFor older women, doing about 82 minutes of strength training a week is linked to the lowest chance of dying from any cause — doing less or more doesn’t seem as helpful, and doing a lot more might even be risky, though the data isn’t certain at very high levels.
