It's a simple equation: post-workout protein equals muscle growth. But that doesn't mean you have to scarf down a chicken breast on your way out of the gym (although if you feel like it, hey, more power to you). There are so many protein bars, powders, and drinks out there now that it can actually start to feel overwhelming - so many delicious sources of protein, so little time! We've rounded up our 10 favorite options just to make it a little easier on you. Eat (or drink) them with a healthy source of carbs, like a piece of fruit, to fill out the post-workout snack and fast-track your way to strong, lean muscles.
