Abstract: A pelvic belt is described for firmly gripping a human torso near the pelvic region. The pelvic belt includes three main components: a U-shaped frame with left and right frame legs, a left arm assembly pivotably mounted to the left frame leg, and a right arm assembly pivotably mounted to the right frame leg. Each arm assembly has four main sub-components: an upper arm, a lower arm, a connecting rod connecting the upper and lower arms rigidly together and an adjustment wing for adjusting the dimensions of the interior region of the pelvic belt. The left and right arm assemblies pivot about pivot pins mounting the arm assemblies to the U-shaped frame. This permits a person to enter the interior region of the pelvic belt when the arm assemblies are pivoted open, and then the arm assemblies are pivoted to a closed position. The pelvic belt can be attached to force resisting mechanisms to build strength over time.

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.
