Lifting lighter weights might make your slow-twitch muscles grow more than your fast-twitch muscles, according to some new ideas.
Lifting heavy weights might make your fast-twitch muscle fibers grow bigger than your slow-twitch ones, according to some new research.
Slow-twitch muscle fibers need longer workout times to grow because they tire less easily. This can be done by lifting lighter weights until you can't lift anymore.
Slow-twitch muscle fibers (type I) can work longer without getting tired compared to fast-twitch fibers (type II), which might help you lift weights for more time before exhaustion.
