An exercise method beneficially and safely affects the lumbar spine and muscles of a human. The method uses a simple exercise device having a substantially rigid body with top and bottom surfaces, and a front and back. The top surface is configured and dimensioned to safely passively extend a human\s lumbar spine when the human lays with her or his stomach on the top surface (e.g. by providing a concave surface with a total angle of concavity of about 10°-30°, preferably about 12°-17°). The bottom surface of the device is configured and dimensioned to allow rocking action in a dimension extending from the front to the rear of the device, and may include two or more spaced rocking strips with front and rear stops. In addition to passively laying on the top surface, the human may occasionally contract her or his lumbar muscles and rock her or his body toward and away from the front of the device to effect rocking action of the device, which assists in strengthening the lumbar musculature and promoting stability of her or his back. The method of use also may include the user pushing on the surface on which the device bottom surface is positioned with her or his arms to move her or his chest away from the top surface of the device while the thighs remain in contact with the top surface, and hold that position for at least a few seconds, so as to passively stretch the front of her or his spine.

A method of beneficially and safely affecting the lumbar spine of a human, comprising the steps of: (a) providing a substantially rigid device having a concavely curved top surface her or and a curved bottom surface, supported by a support surface, which allows rocking action in a dimension extending from the front to the rear of the device, the length of the device between the front and the rear ranges from about 18 inches to less than six feet whereby the top surface is configured and dimensioned so as to allow the human to safely passively extend his or her spine when the human lays with his or her stomach on the top surface; (b) a human occasionally laying with her or his stomach on the top surface, with at last part of her or his chest and thighs supported by the top surface and her or his face extending past the front of the device, so that the lumbar spine is in a safely passively extended position allowing lumbar muscles to become thicker and stronger; and (c) the human occasionally contracting her or his lumbar muscles and rocking her or his body toward and away from the front of the device to effect rocking action of the device, which assists in strengthening of her or his lumbar musculature promoting stability of her or his back.
