[0001] Movable Type Lower Abdominal Exercise Machine [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving lower abdominal exercising apparatus, and is a moving lower abdominal exercise apparatus which facilitates a leg raising operation for training a lower abdomen.

Abdominal Muscle (abdominal Muscle), along with the gluteus and spinal muscles, is a core muscle that is important for proper posture and health.

If the abdominal muscles are weak, the waist will be excessively curved and the stomach will protrude forward, and an incorrect position will deform the body shape, causing back pain.

Thus, strengthening the abdominal muscles can prevent or treat physical imbalance that occurs when the abdomen protrudes forward and the waist is excessively curved, greatly reducing the risk of injuries in intense exercise or daily life.

Abdominal muscles can be distinguished largely from upper abdominal muscles and lower abdominal muscles, and the roles and training methods of the two parts are different.

The lower abdominal muscles firmly hold the anterior pelvic region to prevent the lower abdomen from protruding forward and also to hold the pelvis steadily to prevent physical imbalance such as Pelvic Anterior Tilt.

In addition, the lower abdominal muscles are linked to cooperate with numerous surrounding muscles. It is especially related to the pelvic floor. Pelvic floor muscles prevent the abdomen from falling down, prevent urinary incontinence, prevent urinary incontinence, and enhance reproductive function. do.

Thus, by exercising the lower abdominal muscles, it is possible to maintain a healthy physical condition, to prevent the disease caused by physical imbalance, and to live an active life.

Leg Raise is a typical exercise for lower abdomen training.

Leg raising is the exercise to straighten and extend the legs with the back on the floor and lifting the leg using the force of the lower abdominal muscles to train the lower abdominal muscles and associated coordinated muscles.

Leg raises seem to be a simple exercise, but it is a movement that is carried out with a high degree of freedom of the body. It is a movement that is difficult to perform in a correct posture because the exercise part is not isolated or fixed.

In the case of beginners, breathing is not easy to control and it is difficult to concentrate on the stimulation of the lower abdominal muscles, which can expose to the risk of injury during the exercise and decrease the exercise effect.

In addition to general leg raises, there are also deformed hanging leg raises and lower abdominal muscle training exercises such as Plank. However, these exercises are also difficult to perform without proper guidance without expert guidance.

Various types of abdominal muscle exercises have been proposed to solve these problems. Abdominal Muscle Exercise Equipment is designed to allow the exercise effect to concentrate on the exercise area through isolation of the exercise area, which is an advantage of Machine Exercise, and a fitness center or home is used.

The abdominal muscle exercising apparatus according to the prior art is a device that can perform the most basic leg raising operation in which a leg is lifted while lying on the back with a load applied.

The abdominal muscles exercising apparatus according to the prior art can be used stably on the floor in a state in which a sufficient space is ensured due to a large volume. In addition, since it is constructed using a heavy steel frame so that it can be stably fixed to the floor, it is difficult to move once it is installed, and it occupies a large space even when not in use.

And the back is configured to perform the exercise while lying on the floor. Therefore, in the case of the rehabilitation patient, the novice or the elderly who need to perform the exercise by adjusting the range of motion and the strength and difficulty of the exercise, There is a problem that it is difficult.

In addition, there is a problem that it is difficult to correct the posture because the user can not visually confirm the operation site while performing the exercise while lying on the floor with his back on the floor. As a result, the beginner who has little exercise experience is significantly exposed to the risk of injury or injury.

In addition to the abdominal muscles that help you perform the leg raises described above, there are also a variety of abdominal muscles exercises, and some exercises employ Crunch or Plank.

However, these abdominal muscle exercises are not intended to intensify the lower abdominal muscles but are exercise devices that stimulate the abdomen including the lower abdominal muscles and upper abdominal muscles.

It is very difficult for a beginner to exercise to stimulate the entire abdominal muscles, and if you do not understand the principles of exercise, you may have little or no effect on your workout.

The present invention has been conceived to solve the problems of the prior art, and it is an object of the present invention to provide an apparatus and a method for easily setting up and using a sofa or a backrest, This paper proposes a mobile lower abdominal exercise device that can easily control the intensity and difficulty of exercise without using a plate.

In addition, we want to be able to perform exercise in the correct posture without the guidance of an expert by allowing the user to visually check the operating part while correcting the posture while sitting on the back of the exerciser.

In addition, it is possible to easily exercise even those who are not interested in exercising, for example, by exercising the legs in a comfortable sitting position so that they can perform exercises by using their free hands, .
