The facts on weightlifting and kids

Interesting, one of the myths that has been around, almost forever, is that weightlifting will stunt growth in a small child. The truth couldn't be farther from that. As it turns out, there is a physiological difference between weight lifting when you are mature child, in other words, post-puberty, when you are making testosterone and an immature child. The big difference is that the immature child, if they weight lift, they can increase the different muscle cells, but as soon as they stop lifting, those muscles will revert back to where they were before. In the mature child, with testosterone, allows for muscle cells to duplicate. And duplication of muscle cells allows the child to build bulk. After puberty, with testosterone, in other words, facial hair, groin hair and underarm hair. A small child would weightlift to increase strength, but as soon as they stop lifting, their strength returns to normal. It is safe, and will never affect their growth.
