When you train, you put a lot of pressure on your muscles. The more intense the exercise, the faster your muscles will need to recover over time. Although rest and consistency in exercise is a great way to promote your progress and strengthen your body, you can help with a particular diet. In particular, post-exercise protein is a great way to strengthen your body and muscles. No matter what kind of workout you do (something light or something active), a full meal, snack or protein is a great option when you're done.
