From the makers of the toughest workouts in the gym, comes the HIITMill & HIITMill X.

Unlike a standard treadmill, these machines are self-powered speed and strength training tools designed to build explosive power when used in a High-Intensity Interval Training program.

These High-Intensity machines deliver an effective resistance training platform that captures the benefits of speed and agility training, lateral training and sled training.

Users can now push, drive and sprint with the resistance of a sled, safely and with a smaller footprint.

These easy to use tools allow users to drive up metabolic intensity and make for a more space efficient solution to alternative training methods.

Gear up for one tough and rewarding HIIT workout that members will love to hate.
