Keiser Corporation was founded in 1977 by brothers Dennis and Randy Keiser, who aimed to revolutionize fitness equipment design. Initially, Dennis was hired to create variable resistance machines for a leading manufacturer, which sparked the idea for their own company. In 1978, they introduced the first air-powered variable resistance exercise machines, a groundbreaking innovation that changed strength training dynamics. Over the years, Keiser has focused on developing high-quality fitness products that cater to athletes, fitness enthusiasts, and rehabilitation experts. Their commitment to innovation led to numerous patents in both weight stack and hydraulic resistance designs. Today, Keiser is recognized globally for its advanced fitness solutions, including the popular Keiser M3 indoor cycle. With a legacy of over four decades, Keiser continues to influence the fitness industry by enhancing performance and improving the quality of life for users worldwide.
