Recovery OK, I'm not saying that you need to be strong enough to carry the weight of the world upon your shoulders, but everyone can benefit from some form of resistance or strength training. The only way to curtail the reduction of muscle tissue is to perform activities that force you to stress the muscles of the body beyond what they are used to.
Muscle tissue requires much more energy to exist than does fat tissue.
In addition, many fat-burning enzymes can be found in muscle tissue. Each pound of muscle requires approximately 50 calories each day to sustain it. Increased muscle strength will improve your functional physical capacity. Let's say that lifting your 50-pound child takes every bit of strength you have. After undergoing three months of weight training you develop the necessary strength so that now you are able to lift your 75-pound nephew.
