Description

EXERCISE APPARATUS

The present invention relates to an exercise device capable of performing various kinds of muscle movements.

In recent years, modern people who live in a modern society that is complicated and diversified are experiencing a phenomenon that their stress is accumulated due to the environmental factors such as heavy work, smoke, and noise, and they are weakened mentally and physically.

In addition, as a temporary measure to relieve the mental and physical stress accumulated in this way, too much of the favorite foods such as alcohol and tobacco are brought in close proximity, which not only solves the stress but also adversely affects the body and mind. However, it takes a lot of time and space to do other sports such as walking or jogging. Therefore, it is necessary for the modern people to use various devices such as a gym or athletic facility to perform a variety of exercises in the room as a means of maintaining a healthy mind and body.

Especially, as the number of people who want to have sex pack abs and raise a hot body recently has been increasing, a lot of exercise devices that can perform the exercise to tighten the abdominal muscles can be performed in a narrow room.

In general, there is a sit-up exercise apparatus (exercise apparatus for raising sit-ups) that strengthens the abdominal muscles. Such a sit-up exercise apparatus is a device for training the muscles of the body such as the abdominal muscles by repeatedly folding back and forth around the waist in a bent state of the knee after supporting the back of the plate-type backrest by supporting the foot on the cushion .

However, the conventional technology has the following problems. The conventional sit-up exercising apparatus has a problem in that it is difficult to train the abdomen with the exercising apparatus for training the entire abdominal muscle, especially the upper abdomen, so that a different exercise apparatus must be provided in order to train the abdomen.

Also, since the angle of the backrest is fixed, there is a problem that a user having weak muscular strength can not use it.

In addition, there is a problem that it is difficult to adjust the distance between the support cushion and the engagement cushion in accordance with the leg length of the user.

In addition, since the above-described sit-up exercise apparatus is merely a exercise apparatus for strengthening only the abdominal muscles, there is no exercise effect in the other parts, and since it is a simple repetitive exercise that only the leg exercise is performed, .

In addition, there is a problem that the frame in which the hooking cushion and the support cushion are fixed and the frame supporting the backrest are not folded together, and thus occupies a large space when stored in the room.
