The new StairMaster StepMill 5 offers the core mechanics of our previous models wrapped in a stylish look and enhanced functionality to create a next-generation experience. The SM5 offers plenty of workout options, with such programs 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 your individual progress, along with a custom firefighter test (CPAT) that measures your cardiopulmonary endurance and muscular strength. (Firefighting is considered one of the most physically demanding jobs in North America, which is why the CPAT is such a natural fit with the StepMill.) Finally, with the new D-1 console it’s easy to track your progress thanks to the easy-to-read backlit 2 window LCD display, which tracks your speed, distance, floors climbed, calories burned, and much more.
