     BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    This invention relates to exercise fixtures and more particularly relates to exercise benches. 
         [0004]    2. Description of the Related Art 
         [0005]    A variety of exercise equipment exists to aid in developing and maintaining good physical fitness. Such equipment may comprise fixtures upon or against which a user may stand, lean, sit, kneel, lie, or assume any other exercise position. Examples may include a mat, chair, bench, bar, board, and so forth. Exercise fixtures may also comprise moving parts. Examples may include a treadmill, stationary bicycle, stair-stepper, weight machine, rowing machine, and the like. 
         [0006]    Additional exercise equipment may comprise smaller objects which the user may hold, wear, push, pull, throw, or otherwise physically manipulate. Examples may include barbells, free weights, ankle or wrist weights, elastic bands, balls or other projectiles, jump ropes, batons, poles, and so forth. 
         [0007]    The foregoing types of exercise equipment have their respective advantages and disadvantages. Fixtures may provide greater comfort, safety, and support while exercising, but may also be bulky and difficult to move or store. Smaller objects may be more portable and compact, allowing a freer range of motion in their use, but may also cause clutter or more easily become lost. 
         [0008]    Furthermore, the freer range of motion of smaller objects may be both an advantage and a disadvantage. Disadvantages may include safety hazards such dropping, tripping over, being struck by, or otherwise injured by such objects. Advantages may include the exercise value from handling and supporting the objects in ways that are incidental to their primary use. For example, both free weights and weight machines provide similar resistance as created by the force of gravity, but free weights further exercise the muscles of the user in positioning, balancing, and continuously supporting and stabilizing the free weights so as not to drop them. 
       SUMMARY 
       [0009]    From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method that combines the advantages and minimizes the disadvantages of exercise fixtures and smaller exercise equipment. Beneficially, such an apparatus, system, and method would be lightweight enough to be easily portable, compact enough to be easily stored, have sufficient size and strength to provide support to a user in a number of exercise positions, reduce clutter of any additional exercise equipment, and offer the distinct advantage of further exercising the core and other muscles of the user in positioning and stabilizing the equipment incidental to its primary uses. 
         [0010]    The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and long-felt unmet needs in the art that have proven intractable with currently available exercise equipment. Accordingly, the present invention has been developed to provide an apparatus, system, and method for a core-stabilized exercise bench that overcome many or all of the above-discussed shortcomings in the art. 
         [0011]    The apparatus for a core-stabilized exercise bench is provided with a plurality of modules configured to functionally execute the necessary steps of assuming an exercise position on the core-stabilized exercise bench and using core muscles to actively control a tendency of the core-stabilized exercise bench to roll. These modules in the described embodiments may include a hollow, substantially rigid cylinder, and a pad disposed on an outer surface of the hollow, rigid cylinder wherein the hollow, rigid cylinder is of sufficient size and strength to rollably support a user in the exercise position above a floor. 
         [0012]    The apparatus, in one embodiment, may be configured with a cover disposed on an outer surface of the pad. In a further embodiment, the cover may be water-resistant. In various other embodiments, the apparatus may be between three and five feet in length, and may be between four and eighteen inches in diameter. 
         [0013]    A system of the present invention is also presented for a core-stabilized exercise bench. The system may be embodied by the foregoing core-stabilized exercise bench apparatus, further comprising a first end cap disposed on a first end of the hollow, rigid cylinder, a second end cap disposed on a second end of the hollow rigid cylinder, and a storage cavity enclosed by the hollow, rigid cylinder, the first end cap, and the second end cap. In particular, the system, in one embodiment, may include a carrying strap removably attachable to the first end cap and the second end cap. 
         [0014]    The system may further include a removable component to provide access to the storage cavity. The storage cavity may thereby hold additional exercise equipment, for ease of transport, reducing clutter, and avoiding loss. 
         [0015]    A method of the present invention is also presented. The method in the disclosed embodiments substantially includes the steps necessary to carry out the functions presented above with respect to the operation of the described apparatus and system. In one embodiment, the method includes providing a core-stabilized exercise bench comprising a hollow, rigid cylinder, and a pad disposed on an outer surface of the hollow, rigid cylinder wherein the hollow, rigid cylinder is of sufficient size and strength to rollably support a user in an exercise position above a floor. The method further includes instructing the user in a mode of use of the core-stabilized exercise bench. The mode of use may comprise the steps of assuming the exercise position on the core-stabilized exercise bench, and using core muscles to actively control a tendency of the core-stabilized exercise bench to roll. The exercise position may comprise sitting, lying, or the like. 
         [0016]    The method may also include the step of exercising using muscles other than the core muscles. In an embodiment, the step of exercising may include lifting weights or other similar activities. 
         [0017]    In one embodiment, the method may include rolling the core-stabilized exercise bench. In a further embodiment, the step of rolling may also include stretching, massaging, or otherwise manipulating the muscles.

         [0033]    The schematic flow chart diagrams included herein are generally set forth as logical flow chart diagrams. As such, the depicted order and labeled steps are indicative of one embodiment of the presented method. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more steps, or portions thereof, of the illustrated method. Additionally, the format and symbols employed are provided to explain the logical steps of the method and are understood not to limit the scope of the method. Although various arrow types and line types may be employed in the flow chart diagrams, they are understood not to limit the scope of the corresponding method.

Additionally, the order in which a particular method occurs may or may not strictly adhere to the order of the corresponding steps shown. 
         [0034]    Embodiments of a core-stabilized exercise bench may be used for exercise and therapeutic stretching. The core-stabilized exercise bench has a shape that allows it to roll on a surface. In other words, the core-stabilized exercise bench is not static like a traditional exercise bench, but is free to roll as it is used unless a user actively controls the tendency of the core-stabilized exercise bench to roll. Consequently, the core-stabilized exercise bench allows a user to perform exercises on the bench while requiring the user to stabilize the bench using core muscles. By requiring the activation of additional muscle groups, the core-stabilized exercise bench provides exercise benefits over a traditional exercise bench. 
         [0035]    The core-stabilized exercise bench, in some embodiments, may be used as a platform for lifting weights. A user may lie on the core-stabilized exercise bench and perform weight lifting exercises using the user&#39;s body weight or additional weights, such as dumbbells or other free weights. While performing these exercises, the dynamic nature of the core-stabilized exercise bench requires the user to activate additional core muscles to stabilize the core-stabilized exercise bench. 
         [0036]    Additionally, embodiments of a core-stabilized exercise bench provide a platform to assist in therapeutic scratching. A user may rest on the core-stabilized exercise bench and roll the core-stabilized exercise bench to provide stretching and/or massage to muscles. 
         [0037]    Furthermore, embodiments of a core-stabilized exercise bench are easily transported in their entirety. The core-stabilized exercise bench may be extremely lightweight and may be carried using a simple shoulder strap. This provides an advantage over a traditional exercise bench which is typically bulky and very heavy.
