- Eat 100-200 calories an hour before your workout. You may need to experiment to find what feels best for your body. If you're exercising in the morning, you may want something lighter, like juice or a granola bar.
- Avoid too much protein or fat just before your workout. They take longer to digest than carbs and may lead to gastrointestinal problems that will make you regret working out so close to your meal.
- Stay hydrated. Dehydration leads to a bad workout and poor performance. Drink about 16 oz in the hour before you exercise and sip water throughout your workout. If you're working out for longer than an hour, you may want to use a sports drink.
- Refuel after your workouts. Elizabeth Quinn, About.com's Sports Medicine Guide, recommends combining protein with carbs within two hours after exercise to help your body repair and refuel. Many people find a fruit smoothie is a good post-exercise choice.
