An exercise apparatus designed to simulate the motion of climbing stairs primarily to increase cardiovascular endurance by keeping the heart and respiration rates elevated over a continuous period (aerobics); it also promotes lower-body muscle strength. It may consist of static staircases, or steppers (also known as climbers) consisting of foot pedals or platforms with a manual/hydraulic/air piston drive system, and with side handrails and/or front handlebars. It may include workout program modes to adjust the resistance level, a monitor to display the workout time, distance, speed, calories burned, and heart rate; and handlebars with grip pulse sensors or wireless heart rate tools.
