Keiser Fitness Equipment

Keiser Fitness Equipment is… CHANGING THE WORLD OF FITNESS

For over 40 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 45 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.

More than 80% of the top professional sports teams in the world now train on Keiser machines, including every baseball team in the majors, the soccer champions of nine countries, several American football champions and countless Olympians. They’re joined by everyone from NASA to Navy Seals, medical experts and rehabilitation specialists, and major gyms like LA Fitness.
