Description

TECHNICAL FIELD The present invention relates to an aid for increasing the effectiveness of bench press training.

The purpose of bench press training is mainly to train the pectoralis major muscle. In doing so, the scapulae of both shoulders are brought to the center of the body and the chest is puffed out, and a weight such as a barbell is held with both hands. It is known that repeating the action of holding and moving vertically up and down increases the effect.

In this case, it is effective to place a support device under the back and bring the shoulder blades of both shoulders to the center of the body, which makes it easier for even non-experts to achieve the goal of bench press training. . Also, even an expert can train more effectively.
The reason for this is that without the aid, the bench and the scapula are in close contact, which restricts the stretching of the scapula. This is because it can spread and strengthen the pectoralis major muscle more effectively.
Therefore, various solutions have been proposed.

The invention of Patent Document 1 has the function of bringing the shoulder blades of both shoulders closer to the center of the body with the scapula adduction pad, but the height of the pad is gradually lowered from one side to the other in the length direction of the pad. Also, it does not have a function such as laying a rubber plate or the like on the bottom and attaching a weight to the end to prevent the pad from slipping during training.

The idea of Patent Document 2 is to attach an auxiliary tool to a person performing bench press training or to fix it to a training tool in order to bring the shoulder blades of both shoulders closer to the center of the body.
As with the invention of Patent Document 1, this device does not gradually change the height of the assisting device from one side to the other, and a soft elastic rubber plate or the like is laid at the bottom. not

In the idea of Patent Document 3, a soft elastic rubber plate or the like is laid under the cushion portion to improve the fit to the back, and the rubber plate or the like is placed outside one end of the cushion portion. It does not have the function of extending it and hanging it on the end of the bench with a weight attached to the end to prevent the aid from slipping during training.

Since a fixed portion is provided and gradually lowered toward the waist side, both shoulder blades are sufficiently brought closer to the center of the body, and the assistive device conforms to the shape of the back toward the waist. Familiarity is improved, training can be comfortably performed, and the effect of training is enhanced. Also, the pain in the lower back disappears.

A bendable elongated stopper is connected and extended to the higher end of the auxiliary device, and a weight is attached to the end thereof, and the bendable nature of the stopper allows it to be used as a training bench. It can be hung at the end of the belt to prevent the aid from slipping during training, increasing the effectiveness of training.

The flexible elongated stopper may be an extension of the rubber plate or rubber fiber plate joined to the lower part of the cushion, in which case the structure of the auxiliary tool is simplified.
Also, when a rubber plate or rubber fiber board is used for the stopper, it expands and contracts slightly according to the movement of the body when preventing the slippage, so that the aid fits better on the back.

By laying a soft and elastic rubber board or rubber fiber board on the lower part, the back can fit the aid better during training, and the training can be done comfortably and the effect of the training can be enhanced.
In addition, the height of the assistive device is increased by the thickness of the rubber plate or rubber fiberboard, and the effect of bringing the scapula toward the center of the body is enhanced. Furthermore, since the rubber plate or the rubber fiber board is joined to the lower part of the cushion, the auxiliary tool does not easily slide on the bench, and the slippage of the auxiliary tool is better prevented.

In addition, if a groove is provided from one end to the other end in the lengthwise direction of the central portion of the upper surface of the cushion portion, pressure on the spine is reduced during training, allowing for comfortable training. more effective.
