1. A cable pull station for providing a defined resistance force for resistance training comprising a weight (9), which is arranged movably using a pulling element (7, 17) and on which the resistance force is at least dependent, the pulling element (7, 17) being guided via at least one coupling roller (18), which is designed to transfer the linear motion of the pulling element as a rotary motion to a generator (19) to generate electrical energy,
wherein the coupling roller (18) is designed as a-clamping roller coupling, and
the clamping roller coupling comprises first clamping rollers (25) for transmitting a movement of the pulling element (7, 17) to the generator (19) in a first direction, second clamping rollers for transmitting a movement of the pulling element (7, 17) to the generator (19) in a second direction opposite to the first direction, and an adjusting element (27), wherein the adjusting element (27) is an additional adjusting ring (27) that is arranged on a clamping roller carrier on a generator side; and the adjusting ring (27) is configured to be set relative to the clamping roller carrier with an aid of an adjusting guide in such a way that either all or at least one half of the clamping rollers are held away from clamping positions, so that either complete decoupling or, depending on a direction of rotation, freewheeling can be set between a driving coupling outer ring and an output of the clamping roller carrier.
