An apparatus for physical exercise comprising a resistance arrangement having at least one resistance member adapted for providing resistance forces in at least a first and a second direction. The resistance forces acting through at least one component for operably engaging the resistance members, at least a part of which is rotatable relative to the resistance members. The component for operably engaging the resistance members and the resistance members having engagement elements therebetween capable of transforming the resistance forces of the resistance members into a resistance force which acts to resist rotation of the component for operably engaging the resistance members in both directions of rotation. |
