Abstract

The invention is directed to a method for exercising a weaker of two opposing muscle groups of a person moving an implement, such as a golf club, so that the two muscle groups apply forces in opposite directions to the implement to assist in maintaining the implement in an ideal motion path.

Claims

1. A method of exercising a weaker of two muscles used by a person when moving an implement, wherein, if the two muscles were of appropriate strength, the two muscles would desirably apply opposing forces in substantially opposite directions to the implement to maintain the implement in an ideal motion path, the method performed using a muscle trainer comprising a body and a grip disposed on the body, the method comprising:

(a) the person moving a device having characteristics of the implement in an actual motion path;

(b) determining an orientation of the actual motion path of step (a) relative to the ideal motion path;

(c) the person grasping the grip of the muscle trainer with at least one of the person'"'"'s hands;

(d) when it is determined in step (b) that the actual motion path of step (a) deviates from the ideal motion path, applying a force to the muscle trainer body to urge the muscle trainer body further in the direction of deviation from the ideal motion path, where the applied force is independent of any force generated due to movement of the muscle trainer by the person; and

(e) the person moving the muscle trainer in an actual motion path while steps (c) and (d) are performed.

2. The method of claim 1 wherein the person is a golfer and the method is for exercising the weaker of two muscles used by the golfer when swinging a golf club, wherein, if the two muscles were of appropriate strength, the two muscles would desirably apply opposing forces in substantially opposite directions to the golf club to maintain the golf club in the ideal motion path, wherein:

step (a) further comprises the golfer swinging the device having characteristics of a golf club in an actual motion path;

step (b) further comprises determining the orientation of the actual motion path of the device relative to the ideal motion path; and

step (d) further comprises applying the force to the muscle trainer to urge the muscle trainer further in the direction of deviation from the ideal motion path when the determination is made in step (b) that the actual motion path of step (a) deviates from the ideal motion path.

3. The method of claim 2 wherein the body of the muscle trainer includes a proximal end near the grip and a distal end opposite the proximal end, and wherein:

step (c) further comprises the person grasping the grip of the muscle trainer with both hands, wherein the thumb of the person'"'"'s non-dominate hand is closer to the proximal end of the muscle trainer than is the thumb of the person'"'"'s dominate hand; and

step (d) further comprises applying the force to the distal end of the muscle trainer to urge the distal end further in the direction of deviation from the ideal motion path when the determination is made in step (b) that the actual motion path of step (a) deviates from the ideal motion path.

4. The method of claim 1 further comprising:

(f) while performing step (e), pausing before completion of the movement in the actual motion path and holding the muscle trainer in a fixed intermediate position for a period of time;

(g) resuming the movement in the actual motion path at the end of the period of time; and

(h) repeating steps (f) and (g) until completion of the movement in the actual motion path.

5. The method of claim 1 wherein step (b) further comprises recording video images of the person performing step (a) and observing the recorded video images.

6. The method of claim 1 wherein step (a) further comprises swinging a device having characteristics of an implement selected from the group consisting of a golf club, a baseball bat, a softball bat, a tennis racket, a racket ball racket, a weight lifting device, a weight throwing device, a maul, an axe and a hammer.

7. The method of claim 1 wherein the muscle trainer further comprises an electric motor and a propeller disposed on the muscle trainer, the propeller having a shaft oriented substantially in parallel with the motion path, and wherein steps (d) and (e) further comprise activating the motor to cause the propeller to spin, thereby creating the force on the muscle trainer body.

8. The method of claim 7 wherein the muscle trainer further comprises a switch disposed adjacent the grip, and wherein steps (d) and (e) further comprise setting the switch to activate the motor to cause the propeller to spin.

9. The method of claim 1 wherein the muscle trainer further comprises a force generator disposed on the muscle trainer body and wherein step (d) further comprises applying the force to the muscle trainer body by discharging a pressurized media from the force generator.

10. The method of claim 1 wherein the person is a golfer and the method is for exercising a weaker of two muscles used by the golfer when swinging a golf club, wherein, if the two muscles were of appropriate strength, the two muscles would desirably apply opposing forces in substantially opposite directions to the golf club to maintain the golf club in an ideal club shaft plane, wherein:

step (a) further comprises the golfer swinging the device having characteristics of a golf club in an actual club shaft plane;

step (b) further comprises determining an orientation of the actual club shaft plane of the device relative to the ideal club shaft plane; and

step (d) further comprises

step (d1) applying the force to the muscle trainer to urge the muscle trainer further in a direction behind the ideal club shaft plane when the determination is made in step (b) that the actual club shaft plane of step (a) is located behind the ideal club shaft plane, and

step (d2) applying the force to the muscle trainer to urge the muscle trainer further in a direction in front of the ideal club shaft plane when the determination is made in step (b) that the actual club shaft plane of step (a) is located in front of the ideal club shaft plane; and

step (e) further comprises the golfer swinging the muscle trainer in an actual motion path while step (c) and one of steps (d1) and (d2) are performed.

11. A method of exercising a weaker of two rotational muscles used by a golfer when swinging a golf club, wherein, if the two rotational muscles were of appropriate strength, the two muscles would desirably apply opposing rotational forces in substantially opposite rotational directions to the golf club to maintain an ideal orientation between a club face plane and a club shaft plane during the swing of the golf club, the method performed using a muscle trainer comprising a shaft, a grip disposed about the shaft, a longitudinal axis running through the shaft and a force generator attached to the shaft, the method comprising:

(a) the golfer swinging a device having characteristics of a golf club in an actual motion path;

(b) determining the orientation of the club face plane relative to the club shaft plane at one or more predetermined intervals in the actual motion path;

(c) the golfer grasping the grip of the muscle trainer with at least one of the golfer'"'"'s hands;

(d) when it is determined in step (b) that the club face plane is over-rotated relative to the club shaft plane, applying a rotational force about the longitudinal axis of the shaft to urge the club face plane toward further over-rotation relative to the club shaft plane, where the rotational force urges twisting of the grip in the at least one hand of the golfer and is independent of any force generated due to movement of the muscle trainer by the golfer;

(e) when it is determined in step (b) that the club face plane is under-rotated relative to the club shaft plane, applying a rotational force to the longitudinal axis of the shaft to urge the club face plane toward further under-rotation relative to the club shaft plane, where the rotational force urges twisting of the grip in the at least one hand of the golfer and is independent of any force generated due to movement of the muscle trainer by the golfer; and

(f) the golfer swinging the muscle trainer in an actual motion path while step (c) and one of steps (d) and (e) are performed.

12. The method of claim 11 wherein the force generator comprises an electric motor and a propeller, the propeller having a propeller shaft oriented substantially perpendicular to and offset from the longitudinal axis of the muscle trainer shaft, and wherein steps (d) and (e) further comprise activating the motor to cause the propeller to spin, thereby creating the rotational force about the longitudinal axis of the muscle trainer shaft.

13. The method of claim 12 wherein the muscle trainer further comprises a switch disposed adjacent the grip, and wherein steps (d) and (e) further comprise setting the switch to activate the motor to cause the propeller to spin.

14. The method of claim 11 wherein steps (d) and (e) further comprise applying the rotational force by discharging a pressurized media from the force generator.

15. The method of claim 11 wherein the shaft of the muscle trainer includes a proximal end near the grip and a distal end opposite the proximal end, and wherein:

step (c) further comprises the golfer grasping the grip of the muscle trainer with both hands, wherein the thumb of the golfer'"'"'s non-dominate hand is closer to the proximal end of the muscle trainer than is the thumb of the golfer'"'"'s dominate hand; and

steps (d) and (e) further comprise applying the rotational force to the distal end of the muscle trainer shaft.
