An exercise apparatus includes an adjustable support frame configured be adjusted to raise or lower a waist portion thereof to accommodate users of different heights standing adjacent thereto on a support surface. The exercise apparatus also includes a pivotal upper body support constructed and arranged to pivot relative to the support frame. The upper body support is configured to receive a torso of a user standing adjacent to the adjustable support frame, and facilitate a traction exercise to stretch a spine of the user when the torso of the user engages the pivotal upper body support and bends over the support frame.

A starting block lock having a clamp, top and bottom locking wedges, and a rod is provided. The clamp includes top and bottom portions each having an inside surface and a body between the top and bottom portions. The body includes a cylindrical bore extending on a longitudinal axis between the top and bottom portions. The top and bottom locking wedges each include an outer surface, an inner surface, a side surface, and an aperture extending between and through the outer and inner surfaces. At least a portion of each of the side surfaces slidably contact the inside surface of the clamp. The rod extends through the apertures and the cylindrical bore and is configured rotate in a first direction to linearly displace the top and bottom locking wedges toward each other thereby providing an outward force against the inside surfaces of the clamp to expand the clamp.
