Adjustable and Portable All-muscle Wrist Power Exercise Rod
Invented adjustable and portable wrist power exercising rod is a portable exercising equipment that is used for exercise all the wrist movement related muscles and griping strength. It possesses two exercising modes: waving-mode for exercising muscles for forearm pronation, supination, flexion, and abduction and twisting-mode for exercising hand griping and wrist bending. It also features exercising strength adjustability for different individuals to exercise at their levels.
This application claim priority from the U.S. Provisional Patent Application No. 62/312,045, filed on Mar. 23, 2016, the entire content of which is incorporated herein by reference.
FIELD OF THE INVENTIONThe presented invention relates generally to portable sports exercising equipment, and particularly to the adjustable and portable all-muscle wrist power exercising rod.
BACKGROUND OF THE INVENTIONWrist power is very impotent in racket games, especially in badminton. Every serious badminton player wishes to have a powerful wrist to perform a sudden and fast power smash. The wrist power of a good badminton player shows off during a smash is actually comes from forearm and fingers. Wrist itself does not have any muscles, it is just a joint that allows hand bending, swinging and rotating. All these wrist movements are controlled by the muscles in the forearm. Fingers provide the last control and power at the striking moment. Thus, to improve wrist power, one need to practice the muscles that control pronation and supination of forearm, flexion, abduction and rotation of wrist, and griping of fingers.
Commonly used portable wrist power exercising equipment includes wrist roller, grip-ball, hand griper, and forearm flexor griper. Wrist roller mainly exercises wrist flexion, wrist abduction, and griping strength by using a rod to roll up a string with a weight hanging on it. Grip-ball is a ball made of elastic material and is used to improve finger muscles and grip strength by squeeze the ball with one hand at a time. Hand griper is very similar to grip ball but use spring instead of elastic material. Forearm flexor griper, as it named, is used to exercise the forearm flexor. From above brief description, it is concluded that all these equipment are working on finger muscles and forearm flexor but does not particularly workout the muscles that control forearm pronation and supination which is the strongest wrist movement and actually contributes major power for forehand smash, forehand clear, backhand smash and backhand clear than wrist flexion in a badminton game.
BRIEF SUMMARY OF THE INVENTIONThe invented “adjustable and portable all-muscle wrist power exercising rod” abbreviated as wrist power exercising rod.
The invented wrist power exercising rod provides a complete solution to practice all muscles involved for wrist power. Furthermore, it does not only make the muscles stronger but also enhance the blasting ability of the wrist and forearm. It is also adjustable to meet the requirements of different levels of exercising strength. Obviously, this new exercising equipment does not only benefits badminton players but also many other sports.
There are two exercising modes for the invented wrist power exercising rod: waving-mode and twisting-mode. In the waving-mode, an exerciser waves the wrist power exercising rod (by holding at the handle part 300 with one hand at a time) in certain patterns to exercise the muscles for pronation and supination of forearm, flexion, abduction and rotation of wrist. In the twisting-mode, an exerciser use both hands to twisting the twisting-assembly-1 130 (as shown in
