ABSTRACT:
This machine includes a seat for supporting the user in substantially an upright position with the seat being mounted on a generally A-shaped frame assembly. An inverted U-shaped lever is provided with a padded roller on one end thereof. The padded roller is adapted to engage the back of the user at a position substantially in alignment with the shoulder blades and the other end of the lever is pivotally supported at a position in substantial alignment with the waist of the user. The other end of the user-actuated lever is operatively connected to a resistance applying device. The connection between the user-actuated lever and the resistance applying device includes a variable radius cam for providing a variable resistance force when corresponding movement of the user takes place between a first position with the spine in a forwardly bent position and a second position with the spine in a substantially straight position to provide a full range exercising of the muscles associated with the lower back of the user.
