Abstract
Abstract The present invention teaches a method for strengthening the muscles of the lower back and discloses an apparatus for practicing the method the invention. The method permits the user to partition the load between the back muscles and the arm muscles. In practicing the method, the user positions him/herself on a platform having a protrusion and an ankle engaging element. With the pelvic area supported by the protrusion and the ankles restrained by the ankle engaging element, the user engages supports with his/her hands. The user then lowers and raises his/her torso, distributing the load between the back muscles and the arm muscles, repeating the movements a number of times. At the user's discretion, the weight load can be redistributed between the back muscles and the arm muscles by reducing or increasing the load supported by his/her arms. When the user's back muscles are relaxed and the user's torso is allowed to hang from the protrusion, the vertebrae in the lower back will be extended, and all compressive loads will be eliminated from the lower back.
