Good lord no its the opposite actually.

Well i'm no scientist but as far as i'm aware since ur still growing the bones in your body still haven't reached a certain degree of denseness and through performing physical excercise in prepubertal stages and the during puberty, it helps to increase the maximal peak bone mass compared to non active children/teenagers. You should still wait one or two more years before u start with lifting weights and build the basic fitness.

Ah in case u need some good bodyweight excercise tipps and guidlines, mark laurens book is a must read. He's the real deal and many elite soldiers over the globe are can attest how legit it is. book

All that left to say is git good or go home !
