Creatine Supplements
Creatine is a substance found naturally in your body. Every time you perform any type of intense exercise (such as sprinting, or training with weights), your body uses Creatine to provide your body with energy. Unfortunately, Creatine stores only last for a maximum of around 10 seconds. That's why you can't sprint "all-out" for very long - your creatine stores become depleted.
Adding Creatine to your diet raises the levels of Creatine in your body. This dramatically improves your performance in the gym, or on the field of play. Creatine also speeds up muscle growth, leading to gains of 3 or 4 pounds in less than 7 days. Creatine supplementation has been shown in a number of studies to enhance maximal strength, improve sporting performance in Mixed Martial Artists, and accelerate gains in lean muscle mass.
