FIELD OF THE INVENTIONThe present invention relates to an exercise apparatus and methods of use thereof. In particular, the invention includes an exercise apparatus that is useful for engaging muscles during exercise movements with resistance while minimizing any load bearing on the user's back and joints. Further, the exercise apparatus of the invention provides stability and the user can concentrate on executing a movement with proper form. The exercise apparatus includes a platform and a resistive element receiving system.
BACKGROUND OF THE INVENTIONExercise devices intended to provide balance and strength training for a person's core muscles, including the muscles of the abdomen and back, are known. These devices often include an unsteady platform that tends to rotate, tilt, twist, or otherwise move. A person is to stand and attempt to keep his or her balance on the platform. A user is able to exercise core muscles by regaining his or her balance. Examples of patents disclosing a balancing device for core strengthening include U.S. Pat. No. 4,182,521 and U.S. Pat. No. 7,008,359.
Exercise devices that provide a step device upon which a person may perform cardiovascular exercises are known. These step devices may also be used to perform various strength training exercises. Step devices often include the ability to adjust the height of the step and a step surface that includes a resilient surface upon which a user will step. Examples of patents disclosing exercise devices providing a step device include U.S. Pat. No. 5,683,331 and U.S. Pat. No. 5,562,575.
In addition, exercise devices are known that provide a platform surface with one or more resistive elements. Such exercise devices may have a stable or unstable platform surface. Known resistive elements that may be used in connection with such exercise devices include coiled springs and elastic bands.

The exercise apparatus may be fabricated of any suitable material that provides substantial rigidity but can be easily positioned by a user. For example, but without limitation, the exercise apparatus may be fabricated of a suitable material such as wood, plastic, or a composite material. A skilled artisan will recognize that the suitable material depends upon structural integrity, manufacturing process, and ease of use by user, among other factors. Preferably, the exercise apparatus is fabricated from wood, plastic, or a composite material. More preferably, the exercise apparatus is fabricated from wood or plastic. More preferably, the exercise apparatus is fabricated from wood.

The exercise apparatus 20 generally has a rectangular, plank shape with at least a first positioning length 7 and a second positioning length 2 (
The exercise apparatus 20 has a rectangular shape with a first positioning length 7 of about 3 to 80 inches. The first positioning length correlates to the height or inseam length of the user. By way of example, but not limiting, a user who is about 60 to 68 inches tall may fit a first positioning length 7 of about 30.75 inches, while a user who is less than about 60 inches tall may fit a first positioning length 7 with a length of about 15.25 inches and a user who is greater than about 68 inches tall may fit a first positioning length 7 of about 55 inches. The first positioning length 7 is about 14 to 65 inches in length. Preferably, the first positioning length 7 is about 3, 5, 10, 15, 20, 25, 27, 29.5, 30, 30.75, 31.5, 32, 35, 40, 45, 48, 50, 55, 57, 60, and 63 inches or more. More preferably, the first positioning length 7 is about 30.75 inches.
The exercise apparatus 20 has a platform width that is configured to aide in stabilizing the exercise apparatus while in use. A stable platform allows the user to concentrate on executing exercises with proper form. The platform width of the present invention provides a stable and non-wobbly exercise apparatus. An unstable platform requires a user to concentrate on maintaining balance on the unstable device in addition to concentrating on executing exercises with proper form. The stability of the present invention allows the user to focus on executing exercises with proper form without introducing the need to compensate during the exercise execution for an unstable foundation. The stability of the exercise apparatus of the present invention may aide users who may have balance deficiencies in executing exercises with proper form.
Generally, the exercise apparatus 20 has a platform width 14 of about 1 to 40 inches. The platform width 14 may correlate to the length of the user's feet.
