Have you ever hit a wall in your workout before you've even come close to finishing that last set in the gym or mile on the running trail? One reason for this energy slump may be the foods you're eating or not eating beforehand.

Your body needs energy from food to fuel your daily activities, especially your workouts. Carbohydrates, found in foods like fruit, bread, and milk, are the body's preferred source of energy. The body is very good at turning these carbohydrates into energy to help power you through your workout. Including some protein in your pre-workout snack is also a good strategy to help keep hunger at bay during longer workouts, and the protein helps get your muscles ready for recovery.

Try snacking on one of these foods 30-60 minutes before a workout to help fuel your fitness:

• 

  Banana

  Not only is this grab and go snack a great source of carbohydrates, but it is also full of the electrolyte potassium. Add a smear of peanut butter for a source of protein.

• 

  Yogurt

  Yogurt offers a good mix of both protein and carbohydrates. Add a few berries for an extra dose of carbohydrates to help fuel longer or more intense workouts.

• 

  Dried Fruit

  Dried fruit doesn't just mean raisins anymore. Try something new like dried mangos, strawberries, blueberries, or even apples. Dried fruits are very portable and you can easily pop them in your mouth on your way to the gym.

• 

  Sweet Potato

  It may seem like an unconventional pre-workout snack, but this powerful spud is full of easy to digest carbohydrates. Added bonus — it's bursting with Vitamins A and C.

• 

  Cheese & Crackers

  If you're in the mood for a savory snack before you hit the gym, give this classic pairing a try. Crackers have carbohydrates that will give you a quick burst of energy while the cheese offers some protein.
