Man, I'm starting to feel old, here I am at 21, and noticing that my metabolism isn't there like it used to be. I'm certainly not in bad shape, but am starting to gain weight, just a little bit. The real problem is that I'm also starting to hit the gym kinda hard to put some good muscle on, but its hard to tell what's a result of lifting, and what isn't. Anyone here about that age or remember being that age when you start to bulk up a little? I'm almost 6'2" and about 195, I'd like to drop a little chub, maybe get the tone back....help?
