Diet / Nutrition is huge, I use to play sports etc....and you may be talented, workout etc....but nutrition/diet will help you get to that next level. I think diet/exercise are all related, simple steps will help get you there, ie no pop....giving that up, wil save you some calories etc...I'm currently a fast food addict in some respects, though once my project im working on ends, I plan to refocus, one thing to remember is its much easier to maintain a weight/in shape than it is to get IN SHAPE.
