The Claim
In adults over 60 years of age, resistance training performed more than twice per week does not provide additional benefits for maximal strength or muscle hypertrophy compared to resistance training performed two or fewer times 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.
If you're over 60 and lifting weights, doing it more than twice a week probably won't make you any stronger or give you bigger muscles than doing it just twice a week.
See the scientific wording
In adults over 60 years of age, resistance training performed more than twice per week is unlikely to provide additional benefits for maximal strength or muscle hypertrophy.
After training twice a week, muscles stop growing faster because the body can only build new muscle proteins at a certain rate, and nerves can't activate more muscle fibers than they already are. Doing more workouts doesn't make muscles bigger or stronger because the system is already working at its maximum capacity.
What the research says
1 studyFor people over 60, lifting weights more than twice a week doesn’t make them much stronger or give them much bigger muscles than lifting twice a week — so doing it more often probably isn’t worth the extra effort.
