A popular buzzword among strength training and bodybuilding athletes is creatine but what is it? Creatine is an ergogenic aid that promotes fat-free mass (FFM) by readily creating small amounts of adenosine triphosphates (ATP). This allows for rapid and short bursts of energy which is needed for muscle growth. It is known to fight off fatigue and to allow for greater performance capacity. Creatine is naturally occurring and is fuel for the cells of the body. Adding proper amounts of creatine to your nutrition regimen can assist in building muscle strength and power. Creatine is best utilized as a training aid as it can provide additional energy to enable you to lift a few more reps at a few more pounds. By doing so, you increase muscle mass.
