Lifting lighter weights with more reps might make your slow-twitch muscles grow bigger than lifting heavier weights with fewer reps.
Lifting lighter weights might make slow-twitch muscle fibers grow more than lifting heavier weights, but scientists aren't totally sure yet because the results aren't clear.
Lifting heavier weights might make your fast-twitch muscle fibers grow more than lighter weights, but the results aren't totally certain.
When you lift weights, lighter weights might build more of your slow-twitch muscle fibers, while heavier weights might build more of your fast-twitch muscle fibers, but scientists aren't totally sure yet.
Scientists aren't sure if lifting more weights always makes muscles grow bigger, because their research shows the results are often unclear and sometimes show no effect at all.
