Assault Fitness
Conditioning equipment with no motor and no mercy.
What they're known for
The curved manual treadmill and the air bike — self-powered machines pro teams use to suffer on purpose.
Assault builds the machines conditioning coaches reach for when the goal is output, not entertainment. The AssaultRunner Pro is a curved manual treadmill powered entirely by your stride — no motor, no top speed but yours, and roughly 30% more calorie cost than a motorized deck at the same pace. The AirBike Elite is the air-resistance bike that scales punishment infinitely: harder is always available.
Self-powered is the point. The machine returns exactly what you put in, which makes it both the most honest cardio in the gym and the least comfortable. Military and pro-team adoption is the credential; the burn is the product.
