摘要：

A back traction exercising apparatus is positionable above a flat surface for applying a traction force to the vertebrae of an individual's lower spine as the individual performs exercises on the apparatus and thereby also strengthens selected muscles of his body. The apparatus includes a frame which is positioned adjacent to the flat surface. An armholding peg is attached to and extends vertically from each of the separate arms of the frame to maintain the upper torso of the individual's body in a fixed position with respect to the flat surface as the individual exercises. A spring and bracket assembly is coupled to the apex of the frame and is designed to contact the body of the individual utilizing the apparatus in the area where his legs join his lower torso. The bracket and spring assembly opposes upward movement of the individual's pelvic region as his knees are moved toward his chest and also applies the traction force to the individual's lower spine as he performs exercises on the apparatus.
