Abstract
An exercise apparatus to strengthen the abdominal and oblique muscles in a relaxed state by kneeling and twisting the lower torso. An embodiment configured according to principles of the invention includes a height-adjustable, contoured knee rest rotatingly mounted on a base. Handles extend from the base to where a user may comfortably grasp the handles while kneeling on the knee rest. The user exercises with the present exercise apparatus by urging the user's lower torso to rotate the knee rest. Rotation may be resisted by increasing the inertia of the knee rest with weights suspended from weight arms connected to the knee rest.
