Have you heard the saying that the secret to a fit, healthy body is 80% nutrition and 20% exercise? Quite a bit of research suggests that's true. Proper nutrition does play a huge role in your body's ability to build and maintain lean muscle mass, particularly after working out. This is especially important for strength workouts, even ones using your own body weight.
When you perform strength exercises (think squats, lunges, push-ups, weight training machines, etc.) your muscles start to develop tiny microtears. This sounds a bit morbid, but it's what needs to happen in order for your body to grow any amount of lean muscle to help you stay strong and toned. The tears are easily repaired by rest and, you guessed it, proper nutrition. Without a steady supply of nutrients, your body will not be able to repair as effectively, potentially leading to muscle breakdown. This will lead to the exact opposite of a strong, toned body and your hard work will be wasted. Plus, your whole body is depleted after a workout, and without any nutrients to provide fuel, you're going to feel exhausted, crabby, and most likely dive off the food craving deep end. This is why post-workout meals can be a game-changer when it comes to your physique and overall health.
