About Keiser

Founded in Fresno, California in 1977 by brothers Dennis and Randy Keiser, Keiser Corporation began with a simple but powerful idea: build fitness equipment around the science of human performance rather than the limitations of traditional weight-based resistance. Dennis had spent years designing variable resistance machines for other manufacturers before launching out on his own, and that engineering obsession has defined every product Keiser has built since.

Keiser's technology unites both components of human performance: the force you produce, and the speed at which you produce it. Their pneumatic resistance system uses air pressure rather than weights or magnets, allowing users to train dynamically at speed without the joint stress that comes with traditional equipment. Studies comparing Keiser's pneumatic resistance to conventional resistance training found that muscles experienced greater time under tension, reduced onset muscle soreness, and an ability to train dynamically with greatly reduced effects of shock loading.

More than 80 percent 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, Olympic athletes, and organizations ranging from NASA to the Navy Seals. With over 300,000 M Series indoor bikes sold worldwide, Keiser's cardio equipment is recognized for its magnetic resistance technology, delivering one of the quietest and smoothest indoor cycling experiences available.

Commercial or Residential, Keiser Has You Covered
