When exercising hard you must allow your body to recover. Nutrition is how you build what you break down during exercise. Food should be priority but when you have a 20-30 minute window post workout, supplements are a great way to do this. Quickly ingested and quickly absorbed and put to use building you back up. Go check out Game Plan. See what your coaches are using. We love the products! They taste great and aren't loaded up with other crap we don't need.
