After a workout, it's a good idea to have a little snack. It helps refuel your body and gives you energy after exerting so much. As I've said before, try to eat something rich in protein to help rebuild your damaged muscle tissue. The snack should also be high in vitamin A because just like the amino acids in protein, this nutrient also helps repair microtears that occur in muscles. Not only that but vitamin A helps produce white blood cells so you can fight off infection, which is perfect if you work out in a public facility, especially during cold and flu season. Some great snack ideas include carrots, carrot juice, mango, dried apricots, red pepper, sweet potato, spinach, and eggs.
