Description

Weight Ball Having Finger Stimulating Member

The present invention relates to a weight ball, and more particularly, to a weight ball including a finger stimulation member capable of promoting various exercise effects and peripheral nerve stimulation effects.

Exercise equipment used to strengthen the upper muscles and upper limb (arm) muscles of the body, such as dumbbells, clubs, and weights. Among them, the most commonly used exercise equipment for the development of the upper limb muscles is the dumbbell shown in FIG. 1, and the dumbbell has been used with its material and shape deformed for a long time.

Conventional dumbbells have a structure in which a weight body consisting of a circular or a plurality of disks is integrally fixed to the tip of each of the handles, and the user can develop the upper limb muscles by rotating the arm or wrist while holding the handle of the dumbbell. It was done.

However, the conventional dumbbells as described above are inconvenient to be stored and used in a certain place because they are inconvenient to carry, and there is a disadvantage that it is difficult to expect a variety of exercise effects only because they can only exercise the wrist or arm. In particular, in the case of the elderly whose grip strength (grasp strength) is weakened due to aging of physical function, or patients who need to recover the grip strength through rehabilitation treatment due to an accident, the existing dumbbells are easily missed due to weakening of grip strength during use. It can cause serious fractures that cannot be cured.

In addition, conventional dumbbells always require a certain level of grip strength for use, and there is a problem that individual movements or movements of fingers are extremely difficult while using dumbbells.

And in recent years, the general public practicing life sports or patients in need of rehabilitation treatment want simple and safe exercise equipment that can help improve basic physical strength and rehabilitation treatment, but conventional dumbbells cannot satisfy this problem. have.

Therefore, there is a need for a technology capable of solving problems in the prior art.
