In female mice that exercised a lot for 8 weeks, taking rapamycin — a drug that affects aging — either once a week or three times a week didn’t stop them from getting stronger or improving their stamina.

92%

Giving female mice a certain drug (rapamycin) once a week helps them run more on their own compared to giving it more often or not at all.

92%

Female mice on a weekly rapamycin dose ran more and faster than those on a more frequent dose or no drug, but despite running more, they didn’t lose more fat or get healthier metabolically.

Even when taking rapamycin, female mice still get stronger and fitter from using a weighted exercise wheel — the drug doesn't stop their workout gains.

85%

In female mice that exercised with weighted wheels for 8 weeks, taking the drug rapamycin — even just once a week — made their blood sugar control worse, but doing it less often caused fewer problems.
