Abstract

An exercise device for the lower extremities that can be mounted on a support and has a frame having a first leg and a second leg. The first and second legs have a first end and a second end. The first end of the first and second legs are pivotally connected. A cylinder is connected to the first and second legs for providing resistance. The resistance is produced when the second end of the second leg is moved in a direction toward the first leg. A resilient spring is connected to the second leg. The resilient spring moves the second end of the second leg away from the first leg. A control valve is operatively connected to the cylinder for varying the resistance of the cylinder. A pad is positioned on the second end of the first leg. The pad is positioned to be engaged by the user to pivot the second end of the first leg towards said second leg against the resistance provided by the cylinder. The resilient spring moves the second end of the first leg away from the second leg to return the first leg to the original position. The user repetitively moves the second end of the first leg towards the second leg to exercise the lower extremity.
