The Stairmaster SM916 StepMill is easy to recognize--it's the piece of cardio equipment that looks brutal compared to the others, with a revolving set of 8-inch stairs that closely duplicates the workout of actual stair climbing. Each time you mount the StepMill, the unit's electronically controlled, chain-driven alternator precisely controls the pedal descent, allowing a wide range of users to exercise smoothly within their comfort zones. The resulting step range of 24 to 162 steps per minute will strengthen your legs, boost your cardio, and challenge even the fittest of users.
The backlit LCD display includes a slot for a 15-inch LCD TV. Stairmaster SM916 StepMill offers plenty of workout options, with such programs as quick start, manual, fat burning, calorie burning, speed intervals, custom intervals, random intensity, heart rate intervals, calorie goal, and heart rate zone trainer. The device also offers a nationally recognized multi-stage fitness test that gauges your individual progress, along with a custom firefighter test (CPAT) that measures your cardiopulmonary endurance and muscular strength.
