Strong Support
Even if you do a lot of heavy weight training for 6 weeks, your muscle fibers don’t actually get more of the main building proteins—so the idea that your muscles grow by diluting those proteins with extra fluid probably isn’t right.

Effects of High-Volume Versus High-Load Resistance Training on Skeletal Muscle Growth and Molecular Adaptations
Randomized Controlled Trial
Human
2022The study found that doing lots of reps with lighter weights made muscles bigger, but didn’t change the proportion of the main muscle-building proteins—meaning the growth wasn’t from adding more of those proteins, but probably from other stuff inside the muscle cells.
