The AirRunner treadmill is not just your average gym equipment. It redefines the manual treadmill with superior steel construction, stability, and a streamlined, energy-efficient design.

But what does that really mean? Well, for one, it’s smartly designed. You end up with a high-performance treadmill that’s lightweight — most treadmills in the same category are bulky monstrosities you’d never want to see anywhere except in a gym.

No surprise that it’s fairly portable as well, and it’s even got built-in transport wheels for easier and efficient transport. Beyond lightness and portability, the AirRunner is also incredibly adaptable to just about any type of training space. That means you don’t need to have the most luxurious home gym to fit this in.

But just because it’s lightweight that it’s not packing brute. This is a supremely robust fitness tool, featuring steel frame and handrails, plus corrosion resistant hardware. The slat belt running surface will lasts a long time, too — Assault Fitness says it won’t tire until 150,000 miles.

The motorless treadmill uses no electricity, running instead on energy produced by the person’s own movement. The machine instantly adjusts to adapt to the user’s desired speed, even if they change their pace at random. The AirRunner doesn’t believe in limits. Which explains why it doesn’t have a maximum speed setting. You can run as fast as you can, it’ll keep up.

Because of which, the AirRunner is a perfect companion for fans of interval training. Assault Fitness actually says the treadmill was designed with high-intensity interval training in mind. So if you’re looking for a robust and adaptable HIIT treadmill, look no further.
