Abstract
A collapsible exercise machine for strengthening the core muscles (transverse abdominal, internal obliques, external obliques, rectus abdominis, and erector spinae) includes a frame mounted on a base on which a user sits and manipulates an upstanding lever arm. A seat is convertible between two differently-angled positions for back extension or abdominal exercises. The lever arm rotates a curved tube having a plurality of force adjustment holes. The tube passes through a frame at the upper end of a gas spring, and engaging an adjustment pin on the frame with different adjustment holes changes the amount of resistance. The entire frame above the base can be vertically adjusted to accommodate different sizes of user without altering the relative position between the seat (and user's hips) and the axis of rotation of the lever arm thus not affecting/changing the designated resistance between users of different heights (resistance is affected when the lever arm is lengthened). The connection between the frame and the base enables the unit to be collapsed to a profile small enough to fit under a bed.
