Performance-Driven. Every Mile.
From the makers of the toughest workouts in the gym comes the Throwdown HIITMill. Unlike a standard treadmill, this machine is a self-powered speed and strength training tool designed to build explosive power in a High-Intensity Interval Training program. It delivers an effective resistance training platform that captures the benefits of speed and agility training, lateral training, and sled training — letting users push, drive, and sprint against sled-like resistance, safely and with a smaller footprint. Gear up for one tough and rewarding HIIT workout that members will love to hate.
Key Features
Adjustable resistance control lever for sled-style training demand.
Supports lateral training and max stability under load.
No motor — walking, running, and pushing power the belt.
Backlit display with Bluetooth & ANT+ connectivity.
Commercial Grade — engineered for high-traffic commercial environments
350 lbs (159 kg)
Description
The HIITMill's magnetic resistance brake and adjustable resistance control lever let users dial in sled-style training demand, while the extra-wide 23" belt provides stability under load and supports lateral movement patterns. Because the HIITMill is entirely self-powered, there's no motor — the harder a user pushes, drives, or sprints, the harder the machine pushes back.
The HIIT console features an easy-to-read backlit display tracking time, distance, calories, and pace, with programmable time, distance, calorie, time interval, and calorie interval workout modes. Bluetooth connectivity lets users save and share workout data, while ANT+ compatibility pairs with heart rate monitors and group training displays.
