Minimizing the vertical displacement of the center of mass , there is a coincident increase in energy expenditure.

Training for the sprint

Sprint intervals are an ideal workout because there is no motor. This means that the athlete can start his sprint interval very quickly without having to wait for the motor of the classic treadmill to rotate the belt at a certain speed before being able to shoot.

High Intensity Interval Training (HIIT)

With a curved treadmill you have the possibility to adjust your pace autonomously by increasing the pace, to simulate road running or running at intervals. Because it has no speed limits, the curved treadmill is a great choice for elite level athletes where the required pace is faster than the maximum speed of any commercial motorized treadmill currently on sale.

Training for cardiovascular resistance

Thanks to the revolutionary traction method it offers a higher resistance compared to a classic treadmill. The type of posture used during the exercises, conditions exponentially their cardiovascular capacity and offers an always effective training, which resists always guaranteed results over time.
