Abstract: A torso, muscle and spine exercise apparatus. A base having upwardly extending tubes into which a handgrippable handle is attached, includes a tiltable, rotatable platform upon which a user stands. The user stands upon the platform and fastens one or more harnesses about his waist or torso. Conventional weight stacks are attached to the harness or harnesses at two or four front points and two or four rear points by a cable and pulley system. Rotation of the user's waist or trunk lifts the weights, causing resistance to rotation. The rotatable platform upon which the user stands can be tilted in any direction to rotate freely about the tilted axis. Exercise of certain portions of the spine may be accomplished by a torso stabilizer belt fastened to the handgrippable handle and extending about the user's chest or waist.
