The Claim

In postmenopausal women, performing 3 sets versus 6 sets of resistance training per exercise results in no significant difference in gains in lower-body strength, as measured by 1RM leg press and leg extension after 12 weeks of supervised training.

In plain English

For postmenopausal women, doing three sets or six sets of leg exercises during strength training leads to about the same improvement in leg strength after 12 weeks.

See the scientific wording

In postmenopausal women, resistance training volume does not significantly influence gains in lower-body strength, as both 3 and 6 sets per exercise produce similar increases in 1RM leg press and leg extension after 12 weeks of supervised training.

Why this might work

When older women lift weights, their muscles get bigger with more sets, but their strength doesn’t increase beyond a certain point because their nervous system can’t recruit more muscle fibers than it already does with fewer sets. The body reaches a limit in how much it can activate the muscles during a maximal effort, so even though the muscles are larger, they can’t produce more force.

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

    For older women, doing three or six sets of leg exercises each workout led to the same strength gains after 12 weeks—more sets built more muscle, but not stronger legs.
