The M3i TBT came about because Keiser's athletic customers needed a bike with an upper body component that would hold up to the rigors of athletic performance. They designed a bike built on the sound platform of the proven M3i. The M3i Total Body Trainer is perfect for those seeking a full body workout, allowing them to train upper and lower body at the same time or independently, or even perform single limb rehabilitative movements. Keiser Integrated Technology allows the coach to monitor each athlete’s performance while on the bike in real time on a smartphone or tablet and retain the data to monitor progress.
