The Claim
90 to 120 minutes of strength training per week reduces all-cause mortality risk and increases lifespan in humans.
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.
People who do 90 to 120 minutes of strength training each week have a lower risk of dying from any cause and live longer than those who do not.
See the scientific wording
90 to 120 minutes of strength training per week reduces all-cause mortality risk and increases lifespan
Doing 90 to 120 minutes of strength training each week builds muscle, which helps the body use sugar more efficiently and lowers harmful fats and inflammation in the blood. This reduces strain on the heart and blood vessels, preventing heart disease and other life-threatening conditions. Doing more than 150 minutes causes extreme pressure spikes in blood vessels and overactivates the stress response system, which stiffens arteries and raises the risk of heart problems.
What the research says
1 studyWomen who lifted weights 90 to 120 minutes a week were less likely to die from any cause than those who didn’t lift at all — the sweet spot for living longer was around 80 minutes, but up to 120 minutes still helped. Doing more than 150 minutes didn’t help and might have been risky, but the claim’s range is safe and beneficial.
