The Claim

In intermediate-trained women performing bench press training with loads of 70–85% 1RM over 8 weeks, a velocity loss threshold of 50% results in significantly greater increases in one-repetition maximum strength and triceps brachii muscle hypertrophy compared to a velocity loss threshold of 0% (one repetition per set).

Cause and effect
1 study reviewed
In plain English

Among intermediate-trained women doing bench press exercises with heavy weights over eight weeks, stopping sets when speed drops by 50% leads to larger gains in maximum strength and triceps muscle size than stopping after just one repetition.

See the scientific wording

In intermediate-trained women performing bench press training with loads of 70–85% 1RM over 8 weeks, a velocity loss threshold of 50% leads to significantly greater increases in one-repetition maximum strength and triceps brachii muscle hypertrophy compared to a threshold of 0% (one repetition per set), suggesting that higher within-set fatigue enhances strength and muscle growth under heavy loads.

Why this might work

When muscles are pushed to near failure during heavy lifting, waste products build up inside the muscle cells, which triggers signals that make the muscle fibers grow bigger. At the same time, the nervous system recruits more muscle fibers to keep pushing, making the muscle stronger. This happens even if fewer total lifts are done, because each lift is harder and pushes the muscle harder.

  1. Study: Effects of different velocity loss thresholds on strength, neuromuscular adaptations, and muscle hypertrophy during bench press training in women

    For women who’ve been lifting for a while, doing bench press sets until they slow down by half (50% velocity loss) made them stronger and built more triceps muscle than just doing one rep per set—even though they did fewer total reps. The study proves going harder in each set leads to better results.
