This workout device is used for optimum training of the leg muscles. For this purpose, the user sits on a seat which glides backwards and forwards when the legs are stretched and bent. To achieve the best possible training success and avoid injuries, it is important for the seat to glide easily and smoothly. Since the leg press is used outdoors, bearings and guides have to be corrosion-proof and as lubricant-free if possible. For these reasons, the developers used drylin® W hybrid bearings and two drylin® linear guides.
