An abdominal exercising apparatus should allow the user to strengthen their abdominal and oblique muscles in a comfortable manner. The present invention seeks to strengthen the stomach muscles and do so in a comfortable manner that allows the user of the invention to exercise in an upright seated position, while also providing a massage of the user's back muscles along each side of their spine. The present invention can be used on a bench, chair, couch, or other seating apparatus where it can be used in comfort and while engaged in other passive activities, such as, watching TV. An added benefit of the present invention is that it provides massaging of the muscles on both sides of the user's spine as it is used.

A massage device, including at least two massage elements and at least one bearing element, which is arranged between the massage elements, wherein the bearing element is designed in such a way that the massage elements can rotate independently with at least two rotational degrees of freedom per massage element, wherein the massage elements are surrounded by a tensioning element, which substantially defines the spatial position of the massage elements, wherein the bearing element includes bearing balls, which are arranged circularly, and wherein the bearing balls are arranged in a bearing cage.

A core muscle exercising and resistance training device includes a weighted bar having opposed bar ends adapted to removably mount at least one weight or other force generating element. A pad element is removably and frictionally mounted on the bar, the pad element being constructed from a lightweight foam material having a density within a specific range. The pad has an outer surface with a radius of curvature substantially the same as a normal cervical curvature. In use, the outer pad surface is placed adjacent a user's cervical curve and the weighted bar, the additional isometric resistance generating elements and the pad element act in combination to apply a force upon the user's core cervical curve muscles for improving the user's cervical curve posture by gradually modifying the cervical curvature to conform with clinically desirable curvature.

A massage device includes a plurality of massage rollers including a first-end massage roller, a second-end massage roller, and at least one intermediate massage roller, each massage roller having a spherical shape and being rotatable about a roller axis. Further, the device may be constructed of a coated sponge material for a smooth finish to resist sweat or dirt. The massage balls may have bump and pits to facilitate muscle and tissue stimulation. The massage device is useful in the administration of deep-tissue massage. The device may be used to massage many different minor muscle groups located in the hands and feet, as well a major muscle groups in the upper and lower back, and legs.

A massage tool can include an axle including a root outer diameter, a center stop protrusion, end stop protrusions located at opposing ends of the axle, and at least one set of positioning protrusions located between the center stop protrusion and at least one of the end stop protrusions. An inner positioning protrusion of the at least one set of positioning protrusions is located axially closer to the center stop protrusion than an outer positioning protrusion of the at least one set of positioning protrusions. The outer and inner positioning protrusions each protrude from the root outer diameter of the axle a distance that is less than a distance that the center stop protrusion and the end stop protrusions protrude from the root outer diameter of the axle. Two massage elements each contain a center bore having a bore diameter substantially equal to the root outer diameter of the axle. A length of the center bore of each massage ball is substantially equal to an axial distance between the center stop protrusion and the outer positioning protrusion, and substantially equal to an axial distance between the inner positioning protrusion and a nearest one of the end stop protrusions.
