Re: Early Starter?
Having a six-pack has nothing to do with puberty. Everyone has a six-pack, but it's not visible on everyone. Now, if you have a lot of pubic hair and you're 13, that could suggest that you're an early bloomer. Also, I don't think anyone knows which muscles develop first during puberty.
