Eating smaller, more frequent meals every few hours throughout the day will provide the energy your working muscles need during training and help with recovery.
Have time before a workout? Add some eggs to your breakfast. The added protein will help provide what your muscles need and will keep you feel full longer.
Make sure you fuel up in the morning, particularly before training, but even if you're “off” that day. On the go? Try a piece of fruit and yogurt, granola bar or immediately before working out, sip a Gatorade to get some carbs in you so you can perform.
