The Assault Fitness AirRunner Treadmill is very stable in its construction. With compact solid steel frames and an ergonomic design, it will survive almost all kinds of usage. In addition, this is a comparatively light machine; it weighs 280lbs — which sounds monstrous, but it’s not bad compared to other manual treadmills. It has a maximum user weight capacity of up to 350 lbs (158.7 kg).
The AirRunner is a motorless treadmill and uses no electricity, running instead on the user’s own movement’s energy. This machine can instantly conform to your desired speed, even if you change your output randomly at will. There is no maximum speed setting—if you want to push your limits during a workout, the AirRunner will be up to the task.
The Assault Fitness AirRunner Treadmill has a slat belt design, which means it has individual rubberized slats placed horizontally along the deck. Since the slat belts are a v-shape design, they are nearly indestructible with a flat edge on top. Assault Fitness claims the AirRunner belt will last up to 150,000 miles. That’s right – that’s not a typo: 150,000.
The AirRunner has an LED-infused fitness monitor that helps you in various ways, from selecting workout routines to monitoring your workout statistics. It tracks time, calories burned, distance, speed, watts, pace, and pulse.
