Description

Strength exercise equipment having a structure that can control the weight with the wrist {Strength Exercise Equipment Having A Structure That Can Control The Weight With The Wrist}

The present invention relates to a muscle strength exercise device, and more specifically, the weight can be controlled with the wrist, and by controlling the weight with the wrist, the use of synergistic muscles that are unnecessarily involved, such as the hand or forearm muscles, is minimized and the target muscle to be exercised is exercised. It can improve strength exercise skills by concentrating stimulation, and has a structure that supports the floor and a structure that wraps around part of the user's wrist, preventing safety accidents during strength exercise and preventing injury to the user's wrist. This is about a strength training device that can prevent it.

In general, strength exercise is exercise that applies a certain load (weight) to the muscles, and is included in anaerobic exercise because the muscles do not need oxygen consumption to produce force. For example, the power to lift an object or push an object is based on muscle strength. If the size of the muscle is small, the strength is weak, but as the load (weight) is gradually increased, the strength of the muscle, which is the strength of the muscle, is strengthened.

Strength training increases muscle size, increases motor units so that multiple muscle fibers can be mobilized at the same time, and not only increases muscle strength, but also allows muscles to exert repetitive force without fatigue for long periods of time, such as push-ups or long-distance running. You can develop endurance.

When you think of strength exercise, you usually think of weight training with a heavy barbell, but exercise using light dumbbells, kettlebells, elastic bands, or body weight resistance exercise using your own body weight is also part of strength exercise.

As a prior art related to this, a body consisting of a gripper formed on the upper surface, a hollow receiving part formed on the inside, a filling groove formed on the top of the outer surface, and a stopper fastened to the filling groove, and a buffer part surrounding the outer surface of the body and on the lower surface. A kettlebell including an integrally formed cushioning cover has been disclosed.

However, in the above-described prior art, when the user holds a kettlebell with a heavy load while holding the grip part and performs strength exercises such as sitting up, swinging, or lifting, the weight is located outside the hand and moves away from the center of the body, so it is difficult for beginners. It is difficult to maintain the basic posture, it is difficult to control the kettlebell fixedly, it is unstable due to shaking or tremors when moving up and down, and unnecessary muscles other than the target exercise area are used, causing cheating, and the wrist joint There is a problem that can put a strain on .

To solve this problem, the present applicant has developed a strength training device with the structure shown in FIG. 1.

The structure shown in Figure 1 is a structure worn to surround the user's wrist and prevents the user's wrist from being excessively bent, thereby preventing safety accidents that may occur during exercise.

However, in the case of the strength exercise equipment according to the prior art shown in FIG. 1, it cannot be mounted stably on the ground on which exercise is performed, and its position may change due to unintended external force, causing a person to trip or fall, which poses a safety problem. There is.

In addition, in the case of the strength exercise equipment according to the prior art shown in FIG. 1, there is a limitation in that it is a unified structure that cannot be customized according to the length and size of the user's hand and wrist.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
