Strengthen your muscles. Explosive motions promote the recruitment of muscle fibers. Simply said, the more muscle fibers you stimulate, the more fibers you may exhaust during exercise, resulting in increased muscular growth. The best way to increase muscle mass is by using weight training. Weight training involves using weights, such as free weights or machines, to strengthen your muscles and allow them to grow. As you get stronger, you can add weight or intensity to each set. This will help drive muscle growth. You can also increase muscle mass by doing resistance exercises with elastic bands or your own body weight. These are called explosively-paced movements because they require very fast contraction and relaxation of the muscles involved. They're effective for forcing your muscles into overdrive, which encourages them to grow. Finally, you can increase muscle mass by taking drugs that suppress testosterone or growth hormone. These hormones are responsible for promoting cell division and therefore tissue growth. When they're not released by the brain, excessive buildup of cells occurs only in fat cells. Thus, suppressing these hormones leads to greater size and strength of the muscles. Now that you know how to build muscles quickly, it's time to discuss different methods available for rapid growth.
