Compact and light multi-exercise device providing hyperextension and instability in all directions

Abstract: A small, light, handy personal fitness device offers both support and/or instability during abdominal and other exercises. The lumbar support (1) allows hyperextension during rocking motion. When the user is positioned with buttock in pelvic basin (3a), lumbar support (1) in combination with end contour (4b) gives support such that the body's own weight assists in the upward crunching motion. The inverted domed surface (2) offers instability in all directions. (end of abstract)

BACKGROUND OF THE INVENTION

1. Field of Invention

This invention is an exercise device, specifically relating to increasing the effectiveness of abdominal muscle exercises. The invention is used in conjunction with a variety of abdominal exercises, primarily being placed under the user\'s torso during abdominal exercises. The invention provides several options for enhancing the difficulty to ease of related core body exercises. The shape allows for a combination of support, stability, and instability options.

2. Prior Art

Other exercise devices offering abdominal exercises provide unidirectional instability. The invention disclosed herein, provides all-directional instability. All-directional instability strengthens the core. Furthermore, in addition to muscular tissues, this invention strengthens and conditions skeletal tissues such as ligaments and tendons.

Other abdominal exercise devices do not have the “flying bird with wings open” shape of this invention. The middle hump of this shape provides hyperextension for the lumbar, while the contoured end edge supports the back during crunches.

This invention provides optimal training with a simple, easy, and fun fitness machine. The invention is compact and can fit in a closet or under the bed.

U.S. Pat. No. 4,752,067 to Colonello (1988) shows a device that can be used for crunches. But this device does not have a symmetrical design like the invention disclosed herein. It does not have an inverted dome surface, opposing a “flying-bird” surface, combination thereof providing simultaneous hyperextension and instability to strengthen core and enhance sense of balance and conditioning muscles used for implementation of balance.

No fitness device is has been invented with the combination of design form and particular functions disclosed herein.

SUMMARY OF THE INVENTION

The object of this invention is to provide a compact exercise apparatus that provides numerous exercise options, makes exercising easy and fun, and is highly effective by providing hyperextension in conjunction with instability. The instability is in all directions. The invention could be used to do sit-ups, crunches, and lateral crunches muscles of the arm, upper and lower abdominal muscles, lower back, oblique muscles on the side of the core could be targeted for conditioning. These exercises will sculpt the waist, lower back, buttocks, and sides.

When the invention is inverted, it forms a stable arch, which can be used to do side crunches.

The invention can be solid or inflatable. It could also be rigid or have some flexibility. The shape of the invention makes it easier and more focused than just using a floor.

In summary, this invention provides numerous exercises with instability and hyperextension, and making exercising more effective and fun. The invention offers these advantages while offering

- Compactness
- Ease of use
