Peak fitness exercises, on the other hand, can actually cause your growth hormone to increase naturally, without any of the expense or side effects. In order to better grasp the benefits of peak fitness exercises, you first need to understand that you have three different types of muscle fibers: slow, fast, and super-fast. And only ONE of these muscles will impact your production of a vital hormone called HGH, or human growth hormone, which is KEY for strength, health and longevity. Currently, the vast majority of people, including many athletes such as marathon runners, only train using their slow muscle fibers, which has the unfortunate effect of actually causing the super fast fibers to decrease or atrophy. In fact, neither traditionally performed aerobic cardio nor strength training will work anything but your slow muscles. These are the red muscles, which are filled with capillaries and mitochondria, and hence a lot of oxygen. Next you have the fast type of fiber which is also red muscle, and oxygenates quickly, but is five times faster than the slow fibers. Power training, or plyometrics burst types of exercises will engage these fast muscles. The super-fast ones are the white <b>…</b>
