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 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. Then they introduced the M Series indoor cycles, the first to offer magnetic resistance, for a smooth, quiet ride that elevated the industry standard.
Brands: Keiser is never satisfied with the status quo and strives to find solutions that push the limits of fitness science to elevate human performance. Because…’Good Enough’ Isn’t.
