StairMaster HIITMILL X Incline Treadmill *REFURBISHED*

The StairMaster HIITMILL X is a self-powered treadmill with a fixed incline, not a motorized deck, so speed and resistance come entirely from the user's own effort against a magnetic braking system. It's built with a 23-inch belt, wide enough for lateral shuffles and sled-style pushing drills, plus front-mounted farmer's carry handles rated for up to 100 pounds of plate weight per side. That combination makes it more of a HIIT and speed-and-power training tool than a general walking treadmill. This unit has been inspected and serviced by our technicians before resale.
