Assault AirRunner Manual Treadmill – From the makers of the Assault AirBike, the Assault AirRunner manual treadmill is a motor-free, indoor running machine designed for elite fitness training and High Intensity Interval Training (HIIT). The Assault AirRunner completely redefines the manual treadmill, offering superior steel construction, dependable stability, and no-limits functionality in a streamlined, energy-efficient design. Few high-performance running machines are as lightweight (280 pounds) and portable (built-in transport wheels) as the AirRunner, and its compact footprint makes it adaptable to just about any type of training space. A regular treadmill has a motor which is pushing your legs. With an AirRunner you are the motor. This motorless treadmill uses no electricity, running instead on the energy produced by the user’s own movement. Whether you’re a beginner athlete or a competitor at the highest levels, the 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 uniquely up to the task.

How is indoor running maximized on the Assault AirRunner? Form matters when running. Form drives additional speed and additional efficiency. Sometimes it’s difficult for athletes to understand how form feels. The AirRunner puts even the most beginner runner immediately into the proper form. Once the runner learns the muscle memory, or the “feel”, on the AirRunner then he or she can carry that outside for real-world running. Coaches strive for that feel day in and day out when training athletes for optimal performance. With the AirRunner, without any involvement, they find that sensation immediately and can replicate it exactly. The AirRunner gives the runner more control over his or her workouts and gives instant feedback on speed, calories, pace, watts, and distance. The AirRunner encourages a toe or mid-foot stride, and promotes a heel pull which is definitely good for running form to feel a bit more in the hamstrings.

How is the Assault AirRunner different from other curved treadmills? Some curved treadmills have a higher curve in the back, similar or equal to the degree of curve in the front. While one foot is planting on the front curve generating a downward acceleration in speed into the “sweet spot” in the middle, the opposite foot is moving up the rear curve and thus decelerating slightly (since the belt is traveling “uphill” over the rear roller). This creates a natural braking effect which can cause the runner to actually reduce top end speed potential. The Assault AirRunner has a 9-degree curve in front but only a very minor curvature in the rear. So, that same runner on the AirRunner will accelerate naturally from start to finish of each stride and feel no limits to achieve maximum human speed potential.

“Assault products, in general, allow you to push yourself to a point where mentally you’re uncomfortable but if you push through it, you’re capable of anything. The AirRunner is absolutely no different.” – Ron Ortiz, CrossFit Games Champion
