Abstract
A manual stair step exerciser that simulates the exercise derived from climbing stairs including a support frame with a chain sprocket assembly having multiple equal spaced deployable steps thereon. A drive shaft pulley and belt assembly interconnects to an adjustable magnetic resistant flywheel for sustained user step input of kinetic energy for sustaining self-propelled tread induced motion during exercise.
