These are the game day snacks that I have my athletes keep in their bags. Granola bars, don't care what kind. GoGo Squeeze applesauce packets. All of these snacks have carbohydrates in them. You need to be eating carbs about 90 minutes before you play because carbs are your gas. They're gonna give you energy and they're gonna help you have more endurance throughout the game. Other great snacks that you can include are fig bars, mangoes, granola, pretzels, Popcorners, I get it that all of this is processed. Of course, eat whole foods in your meals as well, but we got to be real, and you guys are traveling a lot. You guys can't pack a sweet potato in your bag sometimes, so these are great options to keep in your bag so that you stay fueled.
