The Westside Ultra Pro Reverse Hyper? (Patents: 5356,359 and 6,491,607b2) decompresses the spine and has no vertical compression on the spine at all.

This is the ‘strap-or-roller’ model that changes with a pin removal – it has two sets of straps, as well as ankle rollers.

It allows for dynamic strength development in the concentric phase while serving as a rehabilitation mechanism in the eccentric phase by gently stretching and depressurizing the spine and creating, in essence, an internal pumping mechanism, filling the spinal column with spinal fluid and the low back muscles with blood.

Anyone who has injured their back knows that the pressure needs to be relieved and circulation restored to the injured area to rehabilitate.
