Video: All the curls in the world won't build your biceps if you aren't eating enough protein. But how does the food you eat benefit your strength? This video breaks down what's happening in your body when you down that post-workout shake.
Protein is made of amino acids, and those amino acids are needed to repair torn muscle fibres. (Your muscles, like the muscle tissue in steaks or chicken nuggets, are made of protein.) Those amino acids also help activate your muscles' satellite cells to help "remodel" the muscle into a stronger version of itself. Watch the video for more on this process, and some visuals showing just how much protein an elite athlete has to eat, compared to your average couch potato.
