Keiser Fitness machines revolutionise exercise. Their pneumatic training system allows the muscles to remain active and engaged through the entire range of motion. As well as this the machines reduce the shock loading on connective tissues and joints. The M series range of indoor bikes have revolutionised the world of group fitness with the use of eddy magnetic current resistance and a aluminum flywheel. The magnetic resistance of the flywheel allows for endless resistance to be applied with no wear or tear on the system.
