"My fave post-workout snack is also my pre-workout snack: I make a banana and peanut butter smoothie with protein powder, almond milk, and a touch of cinnamon, says Andrea Rogers, a certified Pilates instructor and creator of Xtend Barre. "I drink half on my way to the studio to boost my energy and the other half after my workout to rejuvenate my taxed body. Since it's protein-packed, it provides long-lasting energy, and the cinnamon helps to control blood sugar so I don't crash after my workout," Rogers says. "I also like to add in a handful of kale or spinach to add some minerals."
