ABSTRACT:
A lumbar exercise machine having an adjustable pad assembly for engaging the legs above and below the knees while the legs extend generally forward with the feet against a foot rest and the knees bent so that the thighs and calves form an obtuse angle. A lock mechanism is provided to secure the pad assembly in the aforementioned position with the femurs restrained against movement so that the hips, buttocks and thighs cannot move during the exercise. The exerciser then moves his back against a movement arm in opposition to a resistance mechanism connected to the movement arm. The machine is adjustable to properly position a particular user for the exercise. One machine for home use utilizes dead weights plus the user's weight as the resistance mechanism while another machine for commercial use utilizes a compound weight stack as the resistance mechanism.
