Keiser Corporation ^Company

Keiser Corporation is a manufacturer of strength training and fitness equipment for trainers and professional sports teams. The Keiser story begins over 35 years ago when Dennis Keiser was hired to design the first variable resistance machines for a leading manufacturer. Unsatisfied with the limits of iron-based weight training, he and his brother, Randy, found a safer—and more efficient—alternative that uses compressed air, or pneumatics, to provide a smoother, controlled resistance. In 1978, the brothers introduced to the world the first air-powered variable resistance exercise machines for building strength and power. More than 80% of the top professional sports teams in the world now train on Keiser machines, including all 32 Major League Baseball teams, several Super Bowl winners, the football (soccer) champions of nine countries, Olympic athletes and more. They’re joined by everyone from NASA to Navy Seals, medical experts to rehab specialists and from major gyms, like LA Fitness, to neighborhood studios. And with over a quarter-million Keiser indoor bikes sold worldwide, trainers and fitness facility managers agree that our award-winning M Series, featuring our magnetic resistance system, offers the ultimate indoor cycling experience.
