Ideally, you should eat something about an hour before your workout, and then another small meal immediately following it.

Your pre-workout meal should consist of a complex carbohydrate and a little protein. So an apple or some oatmeal with natural peanut butter (or whole grain cereal with skim milk) makes a good pre-workout snack.

Immediately after training (and this is especially important if you are doing weight or resistance training) you'll want to consume some protein. Combining that protein with a faster digesting carbohydrate (like a Rice Chex) can help with with muscle recovery. A whey protein shake with some skim milk is ideal.

Best of luck!
