Sprintbok Walnut

Fully powered by the user’s legs, the Sprintbok knows no speed limitations. Whether training for endurance, sprint or interval runs – the Sprintbok perfectly absorbs any kind of running training through its ball bearing mounted slats.

The running belt’s gentle inward curve renders the motorless treadmill even more benefits for a natural running feel. Shifting the body’s center of gravity enables the runner to change rhythm and speed nearly effortlessly.

Compared to motorized models, the Sprintbok guarantees a heightened, more intense and effective treadmill workout, yielding a higher calorie burn, due to higher level of effort. Distance, sprint and interval runs – all forms of running training can be practiced on the Sprintbok. Exceptionally quiet during use, its cushioned belt reacts instantly to any shift in your speed input. The Sprintbok automatically adapts to all running styles and speeds without any unpleasant, persistent motor noise – this enables fluid change between sprint and slower-paced running.
