The National Gym Association, Inc. (NGA) was born in 1979 and is a nonprofit organization with a dual mission: to support through education and encouragement the art and science of natural strength training and bodybuilding, and to provide more than adequate anti- drug information to support its slogan: Drug-Free Athletes of America.

One of the main ways the NGA does this is by sanctioning bodybuilding competitions throughout the United States, Canada, and abroad. This allows men and women the opportunity to compete against themselves and others in a quest for the achievement of their peak condition. With steroid and other performance enhancing drug use running rampant in the eighties, the NGA severed its ties with all other bodybuilding organizations to discourage such drug users by only promoting drug tested shows. All NGA competitors must pass a polygraph test to validate a minimum drug-free period of seven years The NGA is growing rapidly as promoters and competitors across the United States and Canada are coming aboard and natural bodybuilding is at an all-time high in terms of popularity.

The NGA, it also offers personal trainer certification with an extremely comprehensive home-study certification course. The NGA Trainers/Instructors Certification Course is designed to prepare men and women who have chosen to pursue careers as freelance personal trainers or as private training instructors. The course is therefore designed to satisfy a demanding and well-informed client's expectations for safety, professionalism, and current knowledge.

The NGA also represents the interest of fitness facility owners and managers for the expressed purpose of maintaining the highest possible standards of safety, education, and training, as well as the support of fair athletic and aesthetic competition for the amateur and professional athlete. Setting and maintaining these standards has always been an important issue for the fitness industry, and today it has even greater significance because personal training and private instruction have become a major focus of facility staff and management.
