Keiser began its history of visionary sports science leadership almost 40 years ago, rejecting the constraints of traditional resistance methods and focusing on the biome chanics and needs of the user.

It was this innovative, forward thinking that led the company to challenge the status quo of strength training with
Keiser’s Pneumatic Resistance System. Only Keiser resistance technology allows for training at speed, making true functional training possible for everyone from astronauts to athletes to everyday people.

Keiser M Series bikes revolutionized indoor cycling and continues to lead the pack. Keiser’s culture has continued to demonstrate this heritage of innovation, reimagining the capabilities of the human body and exercise science, and
thinking beyond currently accepted standards to push the fitness industry to new heights.
