An apparatus for exercising the lower back muscles of a user includes a
frame, an arrangement mounted to the frame for resisting forward movement
of the user's hips while maintaining the user's gluteus maximus and
hamstring muscles in a relatively relaxed condition, a lever assembly
mounted to the frame in a disposition for engagement by the upper back of
a user for backward and forward user induced movement of the lever
assembly for exercise of the user's lower back muscles and a resistance
assembly operatively connected to the lever assembly for resisting the
user induced exercise movement with a predetermined resistive force.
