Muscle mass is not just important for your body’s health, but also to provide you with energy. As you reach your thirties and beyond, it becomes harder to maintain your energy level. Exercising and strength training will improve your muscle mass, but it can be difficult to get moving if you are not used to it. You can try Xtra or GoVera to give yourself a healthy boost to become active. Then, once you begin exercising, stay consistent in your workouts so that your body can not only build up, but maintain its muscle mass.
