Actually that is also answered in the anime as well.

Muscular says that his muscle tissue is so incredibly dense that his skin and bone aren't capable of keeping it in check.

So while it might seem like his muscles are growing to enormous sizes, in actuality all thats really happening is that his body isn't fully containing the muscles surrounding his bones.

All Muscular has going for him is that he was likely born with a larger amount of Myostatin then most people, so he simply has more and bigger muscles then a normal person.

In fact this can happen in real life. As there was a boy born whose myostatin levels were incredibly well developed, meaning that he was a super buff child even as a toddler.
