The Claim

In untrained individuals, females accumulate greater total resistance exercise volume than males during 8 weeks of isotonic and eccentric quasi-isometric elbow flexor training, but muscle thickness and estimated one-repetition maximum improve to a similar extent in both sexes.

Description
1 study reviewed
In plain English

Over 8 weeks of specific elbow flexor training, untrained women performed more total work than untrained men, but both groups gained the same amount of muscle thickness and strength.

See the scientific wording

In untrained individuals, females accumulate greater total resistance exercise volume than males during 8 weeks of isotonic and eccentric quasi-isometric elbow flexor training, but this does not result in significantly greater improvements in muscle thickness or estimated one-repetition maximum.

Why this might work

When women do more reps than men during arm training, their muscles still grow and get stronger at the same rate because their muscle cells respond to the workload with the same level of protein building and nerve signals as men, even though they do more work.

  1. Study: Isotonic Resistance Exercise Outperforms Eccentric Quasi-Isometric Resistance Exercise for Increasing Elbow Flexor Muscle Thickness and Estimated One-Repetition Maximum in Untrained Individuals: Exploring the Influence of Sex and Volume.

    Women did more arm exercises than men during an 8-week training program, but both ended up with the same muscle growth and strength gains — meaning doing more reps doesn’t always mean better results.
