Description

REFERENCE TO RELATED APPLICATIONS

This patent application claims the benefit of U.S. Provisional Application No. 61/883,192 filed on Sep. 27, 2013, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a core exercise equipment and more particularly to a portable exercise equipment that has the specific features for working and strengthening abdominal and lower back muscles.

2. Description of Related Art

Exercise devices provide muscle building benefits in a variety of ways. Some exercise devices require repetitive body motion and use pulley or lever assemblies to simulate exercises done with free weights. Others use isometric principles, or utilize resilient devices such as springs or elastic cords.

To balance oneself on a device also adds to the exercise process. In addition a device can be created that will assist with certain exercises to facilitate the exercise itself.

Generally, these devices are designed to promote muscle building and are not designed to specifically strengthen the abdominal and lower back muscles or to be used as part of a universal program by both men and women.

Yet the current abdominal and lower back exercising device have their flaws and can be improved upon.

Such a muscle building mechanism is described herein along with its rather unique features.

SUMMARY OF THE INVENTION

An exercise ball assists in a natural rocking motion that assist in the user crunching the abdominal or flexing the lower back muscles. Furthermore, the user has to balance oneself on an exercise ball which adds to the exercise process giving the user those additional benefits of working small stabilizer muscles in additional to the main abdominal muscles. The core is truly strengthened when the small stabilizer muscles are also strengthened along with the main abdominal muscles. Strengthening small stabilizer muscles also decreases the chance of injury to the core muscles. But, a regular exercise ball does not support a user's head and there is no place for the hand to grip.

When doing the abdominal crunch exercise, the user crunches their abdominal muscles to lift their shoulder and back off the ground. This isn't easy to do. An abdominal rocker has a hand bar in the center for the user to grip and a headrest that supports the user's head. When using the abdominal rocker to do the abdominal crunch exercise, while the user crunches their stomach the user can push the hand bar forward with their arms to rock the abdominal rocker forward which moves the supported neck off the ground and in turn moves the upper body off the ground. This additional rocking motion generated by the arm to the upper body makes it easier and more comfortable to do an abdominal crunch then with no abdominal exercise device. It also prevents tweaked & stiff necks. However, even a regular abdominal rocker can be hard to use. The rocking motion brought forth by the arms may not be enough assist in the crunching of the abdominal muscle.

A regular abdominal rocker cannot be used to exercise the lower back. When using an exercise ball to do lower back exercises, the user has no place to grip to stabilize himself or herself better.

Therefore, there is a need for an all in one abdominal and lower back exercising device that use hand bars and/or headrest to support the upper body and assist in the crunching of the abdominal muscle or lower back muscle while having a semi-spherical base that allows for an even more natural rocking motion along with some instability to work the small stabilizer muscles.
