About Assault Fitness

Assault Fitness is an American brand that has made a name for itself worldwide within the CrossFit community, elite military training, and functional fitness. It all started with one goal: to develop durable, self-powered cardio equipment that pushes every workout to the limit.

Their flagship product, the Assault AirRunner, is a self-powered treadmill that requires no electricity. Users power the machine entirely with their own strength—providing a natural running experience with immediate feedback. Assault Fitness has since expanded its product range to include bikes, rowing machines, and other high-performance equipment.

What makes Assault Fitness unique is its focus on authentic movement, brutal efficiency, and long-term durability. No fancy gadgets or distractions – just hard training in the rawest way.
