Abstract: An exercise machine including a rocker frame movably coupled with a roller assembly via a torsion resistance mechanism is described. The rocker frame may include at least one arcuate rail to provide floor support for a rocking motion of the rocker frame. One or more pedal control structures may be pivotally coupled with the rocker frame near each distal end of the arcuate rail to drive the rocking motion. The roller assembly may be configured to make a rolling motion when the rocker frame rocks. A torque force can be generated via the torsion resistance mechanism as a result of changes in relative positions between the rocker frame rocking and the roller assembly rolling. The force driving the rocking motion can be countered by the torque force to support exercising movements of a user exerting the force.
