The Stairmaster SM5 StepMill  has been the leader in this category for over 25 years because of the remarkable design of the machines, which provide a combination of cardio and strength training. The StepMill has a revolving set of 8-inch stairs that closely duplicates actual stair climbing. Each time the user mounts 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 26 to 162 steps per minute will strengthen the legs, boost cardio performance and challenge even the fittest of users.

The SM5 offers plenty of workout options, such as quick start, manual, fat burner, calorie burner, intervals, bell-shaped, build, mystery challenge, steady, and heart rate zone trainer. The console also offers a nationally recognized multi-stage fitness test that gauges individual progress, along with a custom firefighter test (CPAT) that measures cardiopulmonary endurance and muscular strength. With the new D-1 console it's easy to track the users progress thanks to an easy-to-read backlit 2 window LCD display, which tracks speed, distance, floors climbed, calories burned and much more.

Additional features included are ergonomically designed handrails for support, Polar-compatible wireless heart rate monitoring, dual water bottle holders, reading rack and accessory tray that are positioned within easy reach.
