GAUNTLET 8GX Series StepMill | StairMaster (9-5345-8GX)
GAUNTLET 8GX Series StepMill | StairMaster (9-5345-8GX) –Introducing the all-new StairMaster 8Gx! This powerhouse product provides a superior combination of cardio and strength training with features like a durable, rust free polypropylene construction, ergonomic handrails to support multiple climbing positions and an all-new drive train that delivers smooth, quiet performance. Its combination of quality and innovation delivers a workout that’s quite literally a step up compared to everything else in the gym.

GAUNTLET 8GX Series StepMill | StairMaster (9-5345-8GX) – The 8GX Series Gauntlet StepMill by Stairmaster is a commercial-rated step machine with revolving stairs to provide a cardio workout experience to the exerciser of true stairclimbing. For nearly 30 years, the StairMaster StepMill has been called the toughest workout in the gym. Now you can bring that same toughness to your home workouts with the totally redesigned GAUNTLET. The Gauntlet StepMill is easy to recognize - it's the piece of cardio equipment that looks brutal compared to all the others, with a revolving set of 8-inch stairs that closely duplicates the workout of actual stair climbing. Each time you mount the Gauntlet 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 190 steps per minute will strengthen your legs, boost your cardio, and challenge even the fittest of users.
The Gauntlet Series 8GX StepMill offers the core mechanics of our previous models wrapped in a stylish look and enhanced functionality to create a next-generation experience. The Gauntlet 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 LCD console it's easy to track your progress thanks to the easy-to-read LCD display, which tracks your speed, distance, floors climbed, calories burned, and much more. As a bonus, the LCD console is designed to integrate with the optional MYE 15.6-inch HD Personal Viewing Screen, so you can easily keep up to date with your favorite soap opera or sports team.
