Assault Fitness AirRunner Treadmill Elite Fitness Running Machine

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

The Name Says It All

Tough on You, Easy on the Environment
A remarkable feature, the AirRunner runs on your energy, with zero electrical consumption and a low carbon footprint. You'll be amazed at what a hardcore workout can come from the power of your own two feet. The AirRunner is also the lightest treadmill available with a 33" width.

Optimal for Interval Training

Possibly my best equipment purchase ever in business.
Bought 3 of these for my gym and the results are brilliant, so good for interval training and including them in circuits and group PT sessions. Have members using them instead of the regular treadmills for 5ks etc. Good for my run club too when the pavements are icy. Would like to see some changes to the consoles but still 5 stars from me. Looking to purchase a couple of Air Bikes too now.

Great indoor training!
I don't own this but it is available in the company gym. I have run on the Air Trainer this month every other day. I look forward to being able to buy one for my family to run on when the weather is bad or it's smokey outside. I feel like I have a more natural gait and I can train myself to be more aware of my balance and core positioning. Love the Air Runner and I am thankful to have it available to improve my fitness. Buy it!

Air Runner
So far so good. Air Runner was delivered in some heavy duty packaging. Assembly was very easy, less than half hour. It is a tank, very sturdy and well built. Have only been using it a couple weeks, but it seems very solid. Kicks your butt. Half hour on this thing and you have done quite a workout.

Phenomenal tool
As a gym owner and coach the Air Runner is a phenomenal tool on several fronts: The Air Runner is easier on the body for athletes who find running uncomfortable. The Air Runner also allows us to track several different metrics of work providing some increased variability in our programming. Super stoked to have them in our gym.

I love how convenient the monitor is on the air runner. I can easily access my time, calories, speed, distance, and pace. And with a push of a button, I can quickly change the units from miles or meters to customize to my workout.

Rewards proper running form
I really like using the air runner. There is definitely a learning curve to optimize your output, but once you figure it out it's a great experience. It clearly rewards proper running form, so much so that I strive to mimic my Air Runner form when running outside. As an added bonus, it helps that I have a long gait and can crush my shorter competitors whenever we have runs programmed :)
