## Title
Weight shifting device(s) for athletic training

## Abstract

A swing training system for improving muscle memory and weight transfer during a swinging motion. The swing training system comprises a first device and a second device for a user to stand upon raised flat summits on each device placed approximately shoulder width apart. The user then performs a swinging motion corresponding to a sport such as golf, tennis or baseball while maintaining balance on the devices. Such balance will be committed to muscle memory and will allow for better swings when in actual play.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention pertains generally to devices and methods for training a well balanced swing technique. More particularly, the present invention, in a preferred embodiment relates to devices for improving transfer of weight in a swinging motion for baseball/softball, tennis or golfing.
2. Description of the Prior Art
Heretofore, many inventions have been introduced to assist in developing proper stabilization while transferring weight in the swinging motion, particularly in golf and baseball applications. One such example was proposed by Shimizu, et al., U.S. Pat. App. Pub. No. 2008/0188331, entitled “Swing Training Device.”
According to Shimizu and his co-inventors, in sports that require a swinging motion, i.e. golf, baseball, softball, cricket, tennis, racquetball, and squash, it is understood that the art or science of an optimal swing requires balance. Balance throughout the swing ensures minimal eye movement and proper body mechanics prior to and during the moment of impact with the ball. With regard to baseball, it's has been said that the hardest thing in sports is to hit a moving round ball with a round bat. Without a balanced swing, consistently hitting a baseball is nearly impossible.
When swinging a bat, club etc., during a game or match, it is imperative that prior to impact the player is completely focused on making contact with the ball without worrying about swing mechanics or body balance. Using a training aid to train the body and in turn muscle memory to swing consistently with balance will help athletes during the pressures of a game or competition to maximize their chances for success of consistently hitting the ball.

While these proposals may be beneficial for their respective purposes, a need however still remains to provide a device that can be manufactured inexpensively, as many prior art devices have moving parts or electronics. An additional need that remains unresolved is to provide a device that can be easily stored.
In light of the above, it is an object of the present invention to provide a new balance apparatus that can be manufactured by injection molding, for example, and thereby reduce its cost. It is yet further an object of the present invention to provide a balance mechanism with few moving part or electronics, if any to make the invention affordable and accessible to a larger set of sports enthusiasts. It is an additional embodiment of the present invention to provide a design that is additionally attractive to the consumer due to easy storage.
BRIEF SUMMARY OF THE INVENTION
The present invention specifically addresses and alleviates the above mentioned deficiencies associated with the prior art. More particularly, the present invention comprises a swing training system for improving muscle memory and weight transfer during a swinging motion comprising a first device and second device each having a main portion with a flat summit for placement of a user's foot and a base portion providing stability for the device. The flat summits provide traction for the user's feet by having artificial grass or a traction pad. A user would stand on both devices while practicing a swinging motion such as with a golf club or baseball bat. The user must then attempt to remain balanced on the devices while performing the swinging motion by shifting their weight accordingly.
The devices create raised platforms requiring the user to properly maintain balance to target proper muscle groups to achieve proper swing balance. The targeting of specific muscle groups would allow for strengthening of the muscles and commit the actions to muscle memory. Having the proper swing balance technique committed to muscle memory would translate to performing a better swing motion while actually playing a corresponding sport.
These, as well as other advantages of the present invention, will be more apparent from the following description and drawings. It is understood that changes in the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In one embodiment, the logo 25 may be a ‘Z’ character. The preferred height of the device 20 is 6 inches.
With reference to FIG. 1E, a channel 26 having a shape of a logo is carved out of the flat summit 21. The flat summit 21 has a first surface 22 for a ball 42 of a user's foot 41 and a second surface 23 for a heel 43 of a user's foot 41. The first main portion 29 has a preferred width of 14 inches, and the flat summit 21 has a preferred width of 12 inches.
With reference to FIGS. 2A and 2B, in an alternate embodiment, the device 50 may have a flat summit 51 and a lateral side 54. The flat summit 51 has a traction surface 52 for providing a grip for a user's foot 41.
With reference to FIG. 2C, in an underside view of the device 50, cavity 59 is open and allows the device 50 to be stacked upon another in the same footprint and substantially covering a second device 50.
