Abstract

A training device (10) for strengthening the swing muscle groups of a golfer while enhancing proper muscle memory wherein, the device (10) includes a hollow ball (21″) having a meridian line (22) that divides the ball (21) into two visually distinct hemispheres (23), (24) and further including two pairs of elongated apertures (27A), (27B), (27C) and (27D) which are dimensioned to receive the user'"'"'s hands and which extend into the hollow interior of the ball (21″).

Claims

1. A sports swing training device for strengthening the core muscle groups employed in a proper swing and enhancing muscle memory where, the device comprises:

a generally spherical member including a hollow weighted ball having a sidewall with an exterior surface and an interior surface, the interior surface defining a hollow interior, the ball including two hemispheres wherein each hemisphere is provided with a pair of elongated apertures dimensioned to receive a user'"'"'s hand and each aperture extends into the hollow interior of said generally spherical member;

wherein the sidewall of the hollow ball is provided with a wieghted insert encased within the sidewall between the exterior surface and interior surface, the insert being centered on a juncture of the two hemispheres.

2. The device as in claim 1 wherein the sidewall of the hollow ball has a uniform thickness.

3. The device as in claim 2 wherein said two hemispheres are visually distinguishable from one another.

4. The device as in claim 3 wherein said two hemispheres are separated from one another by a meridian line.

5. The device as in claim 4 further including an enlarged visual target bisected by said meridian line.

6. The device as in claim 1 wherein the sidewall of the hollow ball has a non-uniform thickness.

7. The device as in claim 6 wherein said two hemispheres are visually distinguishable from one another.

8. The device as in claim 7 wherein said two hemispheres are separated from one another by a meridian line.

9. The device as in claim 8 further including an enlarged visual target bisected by said meridian line.

10. A sports swing training device for strengthening the core muscle groups employed in a proper swing and enhancing muscle memory where, the device comprises:

a generally spherical member including a hollow weighted ball having a sidewall with an exterior surface and an interior surface, the interior surface defining a hollow interior, the ball including two hemispheres wherein each hemisphere is provided with a pair of elongated apertures dimensioned to receive a user'"'"'s hand and each aperture extends into the hollow interior of said generally spherical member;

wherein the sidewall of the hollow ball has a non-uniform thickness, and wherein a first portion of the sidewall has a greater sidewall thickness than a second portion of the sidewall diametrically opposed to the first portion, and the first portion is centered on a juncture of the two hemispheres.

11. The device as in claim 10 wherein the sidewall of the hollow ball is provided with a weighted insert.

12. The device as in claim 11 wherein said two hemispheres are visually distinguishable from one another.

13. The device as in claim 12 wherein said two hemispheres are separated from one another by a meridian line.

14. The device as in claim 13 further including an enlarged visual target bisected by said meridian line.

15. The device as in claim 10 wherein said two hemispheres are visually distinguishable from one another.

16. The device as in claim 15 wherein said two hemispheres are separated from one another by a meridian line.

17. The device as in claim 16 further including an enlarged visual target bisected by said meridian line.
