The AirRunner treadmill trainer from Assault Fitness is designed to allow users to go from 11MPH to 0MPH in just 2 seconds, making it easy to transition to the couch after a workout. This treadmill runs on human power, with your movement powering the belt and determining its speed. With the ability to change speeds at will, the AirRunner is ideal for high intensity interval training (HIIT) and Tabata-style workouts. Unlike motorized treadmills, the AirRunner can respond quickly to your speed changes, providing a more efficient workout experience. Measuring 33" wide and weighing just 280 pounds, this treadmill is both compact and lightweight. Its energy consumption is dependent on the user's input, making it a sustainable option for home workouts.
