Throwdown® HIITMill X

And You Thought Our Stairs Were Tough.

The Throwdown® HIITMill X is a true game-changer in high-intensity interval training. Unlike traditional motorized treadmills, this self-powered, resistance-driven machine is built to push athletes beyond standard cardio, combining speed, strength, and sled-style resistance into one brutally effective training tool.

Designed specifically for HIIT circuits and performance training, the HIITMill X challenges users to sprint, push, and drive against resistance, amplifying every interval for maximum metabolic output. With its extra-wide turf belt, magnetic resistance brake, and farmer’s carry arms, this machine delivers explosive power training, agility work, and calorie-torching conditioning in a compact, portable design.
