The Claim

In postmenopausal women, performing three sets per exercise of supervised lower-body resistance training for 12 weeks is sufficient to significantly increase leg lean mass and lower-body strength compared to no training, but does not achieve maximal hypertrophy.

Cause and effect
1 study reviewed
In plain English

For postmenopausal women, doing three sets of supervised leg exercises twice a week for 12 weeks can increase muscle mass and strength in the legs compared to not exercising at all, but it does not produce the maximum possible muscle growth.

See the scientific wording

In postmenopausal women, 3 sets per exercise of supervised lower-body resistance training for 12 weeks is sufficient to significantly increase both leg lean mass and lower-body strength compared to no training, but does not maximize hypertrophy.

Why this might work

When you lift weights, the pulling and stretching of muscle fibers sends signals inside the cells that tell them to build more of the proteins that make muscles contract. More sets mean more of this signal, so muscles grow bigger over time. At the same time, lifting weights also trains the nerves to fire more strongly and efficiently to the muscles, which makes you stronger — but this improvement plateaus after a certain amount of lifting, even if you keep doing more.

  1. Study: Resistance Training Volume Enhances Muscle Hypertrophy, but Not Strength in Postmenopausal Women: A Randomized Controlled Trial

    Doing three sets of leg exercises three times a week for 12 weeks helped postmenopausal women build more muscle and get stronger compared to not exercising at all. Doing six sets built even more muscle, but didn’t make them any stronger—so three sets are good enough for strength, but not for maximum muscle growth.
