Natural Bodybuilding simply refers to a special type of bodybuilding regimen. It's one of the many different approaches that an individual can take when competing in the sport of bodybuilding. Natural Bodybuilding is the most commonly used term when performance-enhancing drugs, such as anabolic steroids, human growth hormones or other restricted drugs, are not used to aid in the building of muscles by a bodybuilder. Prohormone and diuretics are also substances that are illegal in the sport of Natural Bodybuilding.

There are governing bodies that regulate and compose the rules on Natural Bodybuilding. Such organizations include NANBF (North American Bodybuilding Federation and NPA (Natural Physique Association). On the professional front, organizations such as the WBNF (World Natural Bodybuilding Federation), INBA (International Natural Bodybuilding Association) and OCB (Organization of Competitive Bodybuilders) look over and govern the sport. These organizations state that the natural bodybuilding method is more centered on competition and healthy lifestyle.

Drug testing bodies also work hand in hand with Natural Bodybuilding organizations. All of the different local and national drug/anti-doping bodies are organized under the jurisdiction of the World Anti-Doping Agency (WADA). The agency includes such anti-doping agencies as Australian Sports Anti-Doping Agency (ASADA) and New Zealand Sports Drug Agency (NZSDA). These anti-doping organizations work closely with the different Natural Bodybuilding organizations. They help each other implement and test the rules to keep different competitions safe, legitimate, and within the bounds and rules of Natural Bodybuilding.

Natural Bodybuilders are just as strong and big as bodybuilders who take performance-enhancing drugs. They might even be healthier than their 'unnatural' counterparts since they do not take in any damaging chemicals in the process of training. Some studies have shown that bodybuilders who have admitted to taking performance-enhancing drugs grow older more quickly and their internal organs, such as the heart, kidney, and liver, tend to show signs of premature aging or damage. This is a heavy price to pay for taking a shortcut to a good physique!

Natural bodybuilders tend to be less bulky than bodybuilders who use performance-enhancing drugs. This is because the natural size or development of the body is not overextended or overexerted.

Natural Bodybuilding takes time, passion and discipline to achieve. There is no shortcut to achieving this, nor should there be. Consistency is the key in achieving the desired strength, size and physique. Natural Bodybuilding involves a well-balanced diet, enough sleep, and regular and vigorous exercise. Some people tend to build muscles quickly while others need a little more time and effort to see or notice any results at all. While results may vary from case to case, virtually everyone agrees that Natural Bodybuilding is the only way to go to achieve muscle gain.
