A guy I work with has 13 and 15 year old boys that are heavy into soccer. They started 2-a-day conditioning and it is rather warm and they got beat down. He was asking me what a good pre-practice meal and/or supplement that would be good for them to maintain their energy levels and keep them going during a long strenuous practice. Also something post workout as well. I figured I would tap into the vast knowledge on this site for some information and tips to help them out. Any info you can provide would be greatly appreciated.
