At Keiser, our products look and feel different because they are different. We begin our engineering process around the form and function of the human body, resulting in science-backed products that optimize your workout experience. From pneumatic resistance, to the magnetic resistance system, to the rear flywheel on the M3 to reduce damage from sweat, we build better products that offer better results for the people who use them, and the people who own them.
Keiser is driven by the pursuit of perfection… and pumping iron is imperfect. Keiser's science-backed pneumatic resistance systems produce a purer resistance, consistent and controlled to accommodate for how the human body naturally reacts throughout the entire range of motion.
With over 300,000 of our M Series indoor bikes sold worldwide, leading fitness facilities already know that our cardio equipment is built on magnetic resistance technology for the quietest, smoothest workout you’ll ever experience. See how quality in design makes a difference.
Whether you’re an astronaut, competitive athlete, or simply want to improve core flexibility, mobility, stability, balance and strength, Keiser helps build true, activity-based functional training into workout programs for daily life. True functional training requires training at speed – something you can ONLY do with Keiser resistance technology.
