Stairmaster HIITMILL X

From the creators of the toughest workouts in the gym come the HIITMill and HIITMill X. Unlike a traditional treadmill, these machines are self-powered tools designed to deliver intense speed and strength training, making them the perfect addition to any High-Intensity Interval Training (HIIT) program.

The HIITMill and HIITMill X offer more than just cardio—they provide a dynamic resistance training platform that captures the benefits of speed, agility, lateral, and sled training. Users can push, drive, and sprint with the resistance of a sled, all while working within a safe, space-efficient design. These machines help maximize metabolic intensity, delivering a powerful, full-body workout without the need for bulky equipment.

Easy to use yet undeniably tough, the HIITMill and HIITMill X are built to challenge even the most seasoned athletes. Get ready for a high-intensity, low-impact workout experience that members will love to hate—and results they’ll love to see.
