Description

Abdominal muscle training apparatus

The present invention relates to an exercise device that can train belly fat through sit-ups, and relates to an exercise device for belly fat that can be used as a chair at home or in an office.

In general, sit-ups are well known as an exercise to strengthen the belly.

In order to perform these sit-up exercises, a separate sit-up exercise device is required.

1 is a perspective view of a conventional sit-up exercise device. As shown, the conventional sit-up exercise device 1 includes a support plate 10 for supporting the upper back from the hip to the backrest, and the support plate 10. It consists of a vertical support 20 for supporting inclinedly from the ground, and a footrest 30 provided on the vertical support 20 so as to fix the lower body.

Therefore, it is possible to perform a sit-up exercise by lying on the support plate 10 while hanging both feet on the footrest 30 .

However, the conventional sit-up exercise device 1 as described above has a problem in that the support 10 is inclined, so that it is difficult to use for users with weak physical strength due to high exercise intensity.

In this case, the above problem may be alleviated to some extent by adjusting the height of the vertical support 20 and lowering the inclination of the support plate 10, but nevertheless, the sit-up exercise is still high in strength for women and the elderly. Sit-up exercise equipment in the country is under-utilized.

In addition, since the conventional sit-up exercise device 1 can be used only by visiting the gym, there is a problem in that it is not easy to train the stomach at home or in the office.

In addition, in the conventional sit-up exercise device (1), when exercising due to the hard supporter (10) for the back and buttocks, excessive force is applied to the waist, neck, back, and shoulders, so that you cannot concentrate on the exercise of the belly fat, the neck and the back As the force is distributed to the shoulder, it is difficult to continue the abdominal exercise.
