When young men who don't exercise start lifting weights, any number of reps between 3 and 28 changes their fast-twitch muscle fibers in the same way, making them more efficient, and this happens after 8 weeks of training.

Muscular adaptations in response to three different resistance-training regimens: specificity of repetition maximum training zones

Randomized Controlled Trial

Human

2002 Nov

The study showed that lifting weights with different numbers of reps all made muscles change in the same way for young men who don't usually exercise, which matches the claim exactly.

Similar Assertions

When young men who don't normally exercise do eight weeks of weight training, their fast-twitch muscle fibers get bigger, but their slow-twitch fibers stay the same size and the overall mix of muscle types doesn't change.

Lifting lighter weights might make your slow-twitch muscles grow more than your fast-twitch muscles, according to some new ideas.

When women who haven't trained before do weightlifting for 6 weeks, their fast-twitch muscle fibers change: some decrease while others increase, and this happens no matter how fast or hard they train.

Lifting weights with fewer reps (3-11) builds more muscle than doing lots of reps (20-28) in young guys new to training, especially after 8 weeks.

Lifting lighter weights many times in a row might help grow certain slow-twitch muscles better because they stay working longer.
