    More info


    The HIITMill X by StairMaster is a self-powered, non-motorized treadmill with fixed incline designed to develop speed, strength, and explosive power when used in a HIIT High Intensity Interval Training Program. The StairMaster HIIT Mill will deliver an effective resistance training platform that drives up metabolic intensity and captures the benefits of speed and agility training, lateral training and sled training. Users can now safely push, pull, drive and sprint with the resistance of a sled but work within a smaller footprint. The HIITMill is aesthetically appealing to athletes at all levels of sport – professional, college, CrossFit, and UFC athletes. The HIITMill manual treadmill also invites simple activities with little to no learning curve such as walking on an incline, running hill sprints, or hiking with light resistance for general cardio training.

    The HIITMill X features a 3mm custom cushioned PVC belt that provides added grip for heavy pushing and carrying activities. This unique cushioned belt adds more friction to the system and will limit lighter users under 110 pounds from freely walking and running without pushing off the forward handles. The advantage of the HIITMill X is significantly more traction for heavy pushing and heavy lifting activities. The HIITMill X also features the Farmers Carry lift arms allowing for the addition of up to 90 lbs of weight plates to be added on each side. The arms themselves weigh 10 lbs so the total available max carry weight per side for bilateral or unilateral carries is 100 lbs.
