The StairMaster 4G StepMill is the ultimate cardio solution for gyms, hotels, multi-housing fitness rooms, and boutique studios looking to offer a world-class stair climbing experience in a smaller footprint. Engineered with the same legendary performance as the StairMaster 10G and 8Gx, the 4G delivers intense calorie-burning workouts through a low-impact stair climb that keeps members challenged, motivated, and coming back for more.

With a space-saving design (137 × 74 cm) and only 244 cm ceiling clearance required, the StairMaster 4G is purpose-built to fit where larger StepMills cannot, without compromising on workout intensity or durability.

Available with a choice of OpenHub console options, the 4G supports Bluetooth workout tracking, heart rate telemetry, USB charging, entertainment features, and more—giving operators the flexibility to match their facility’s needs and budget. For operators, maintenance is hassle-free thanks to a quick-access service panel and a heavy-duty powder-coated steel frame designed for reliability in light commercial environments.

If you’re searching for a compact stair climber, light commercial StepMill, or a StairMaster for hotels, apartments, or boutique gyms, the StairMaster 4G is the perfect fit—combining legendary performance, unmatched durability, and the space efficiency your facility demands.
