About Keiser

For over 30 years, Keiser has been changing the way people of diverse ages and abilities exercise, while helping to improve their performance and quality of life. However, this success story began over 35 years ago when Dennis Keiser was hired to design the first variable resistance machines for a leading manufacturer. A year later he launched "Commercial Design", a consulting engineering company that specialized in exercise equipment design. In 1976 Dennis' brother Randy joined him and a year later they formed Keiser Corporation. After a number of patents in both weight stack variable resistance design and hydraulic resistance design, Dennis applied for patent protection on a totally new concept for variable resistance using compressed air (pneumatics). In 1978 the brothers introduced to the world the first air powered variable resistance exercise machines for building strength and power.

Since its inception, Keiser has always been at the cutting edge of the industry, and remains there today with a full range of products for the young, and the young-at-heart. From elite testing equipment to strength and stretching machines, Keiser has it all. As a matter-of-fact, Keiser has been involved in over 80 peer reviewed and published research studies on strength training and its effect on aging, making it the undisputed leader in serving the needs of an aging population, the fastest growing segment of the market. But the secret to Keiser's longevity and success has always been its people and the success experienced by their customers.
