The present invention relates to a multi-purpose exercise device, and more particularly, to a multi-purpose exercise device that can perform various types of exercises for training various types of muscles and organs, and select an exercise intensity according to the user's fitness and posture. .

The purpose of our exercise depends on the age of the person. For example, in childhood or preschool children, except in the case of obese children, in most cases, no special exercise equipment is required, and play itself is an exercise for physical development.

In addition, adolescence requires a comprehensive exercise in order to develop a healthy body, to prevent or treat various adult diseases in the middle age, and to minimize and prevent the degeneration of various muscles and organs in old age or adulthood. Furthermore, in the case of various athletes, rehabilitation exercises are performed to reinforce or rehabilitate damaged or deteriorated body muscles in order to increase muscles of specific parts necessary for each sport.

On the other hand, the above various exercises can be divided into aerobic exercise, anaerobic exercise and mixed exercise, the aerobic exercise refers to the exercise that can be made as aerobic metabolism of most of the energy supply required for the exercise performance, the aerobic exercise is aerobic In contrast to exercise, it refers to a movement that produces energy without using oxygen, and a mixed exercise refers to a combination of aerobic and anaerobic exercise.

Aerobic exercise is low-intensity, long-term exercise, such as walking, abdominal breathing, aerobics, jogging, marathon, swimming, cycling, mountain climbing, strong rhythmic exercise to strengthen the cardiopulmonary function to maintain youth, aging It is a good exercise to treat obesity because it uses fat as energy.

Anaerobic exercise is a short-time exercise such as weight exercise, diving, throwing, weightlifting or short distance (100m) running, which improves muscle strength and endurance (agility, flexibility), significantly increases heart rate, high exercise intensity, Because glycogen stored in muscle is used as an energy source, a lot of lactic acid (= fatigue substance) accumulates during energy generation.

As described above, aerobic exercise, anaerobic exercise, and mixed exercise have their own characteristics, so some exercise is not good and some exercise is not good exercise. Depending on the user's exercise purpose, one or two exercises are mixed or performed. It is desirable to choose an exercise.

On the other hand, if you deviate from the standard body shape through bad eating habits or lifestyle for a long time, it leads to the so-called obesity state, and if left unattended, various adult diseases and complications such as heart disease, hypertension, diabetes, etc. In order to solve this problem, exercise and diet for obesity treatment should be performed.

In particular, there are many factors that cause obesity, such as bad eating habits, lack of exercise, psychological factors, genetic factors, etc., but in the short term is caused by the imbalance between energy intake and consumption.

Therefore, in order to treat obesity, a controlled diet and proper exercise are necessary, and it is known that it is desirable to reduce the body fat of the body by ingesting proper nutrients and calories as a diet, aerobic exercise and muscle strengthening exercise to burn fat in blood vessels. .

However, if you try to lose weight quickly in a short time, you can harm your health by side effects such as constipation, diarrhea, hypotension, dehydration, liver dysfunction, decreased immune activity, cardiac arrhythmia, protein imbalance. Therefore, in order to safely treat obesity while avoiding the so-called 'yo-yo', comprehensive and continuous treatment through diet, exercise therapy, and drug therapy is necessary.

In the case of aerobic exercise, in the first few minutes, a small amount of ATP, CrP, and glycogen stored in the muscle are used to gain energy, and then blood glucose is used to give a lot of energy and continue exercise. If you do so, the percentage of fat consumed in the calories increases gradually, and about 30 minutes after the start of exercise, the fat is burned to give energy for exercise. Therefore, if you want to diet, if you want to consume fat stretching, weight training and aerobic exercise to be sure to consume more than 30 minutes or 1 hour to consume fat.

If you're a young person, it's best to mix aerobic and aerobic exercise with you.

Patent No. 177530 describes the body fat of obese people more precisely to control the weight of obese people by using low-intensity aerobic exercise that exercises the muscles that are not normally used by shaking the whole body in the symmetrical direction, that is, the S-shape transverse direction. Slider type low-intensity aerobic exercise equipment has been proposed that can reduce.

On the other hand, as the importance of exercise to the modern man has been greatly emphasized, various kinds of exercise apparatuses are provided, but the various kinds of exercise apparatuses provided so far are merely for raising or releasing muscles. In addition, such exercise equipment is a serious problem that causes adverse effects on the spine or muscles because it gives an irritating stimulus to the body if the exercise through the correct posture is not made.

In addition, in the case of a conventional exercise equipment is not only a problem that the biased movement is made by the local muscle training of the body, but also in the case of an exercise machine capable of full-body exercise, such as a treadmill requires power using a separate motor As a result, there are many problems that increase the cost and waste of power.

In consideration of these problems, Utility Model Registration No. 381130 discloses an exercise device that can perform aerobic exercise without using power.

As well-being culture is in vogue, many recognize that it is important to stay healthy by exercising. In accordance with this trend, a lot of exercise equipment or fitness equipment has been recently produced. Among them, the treadmill can be used not only in a narrow place but also for running, which is the basis of aerobic exercise. most commonly used in centers and health clubs. In addition, the bench press mechanism (barbell) is used to develop the muscle by lifting the barbell, which is used as a representative fitness equipment for anaerobic exercise.

However, since the conventional treadmill and the bench press mechanism are manufactured separately, they need to be purchased separately in order to use them, which requires a lot of manufacturing and purchasing costs, and also takes up a lot of installation area.

Utility Model Registration No. 396991 installs a barbell set and iron rod on the frame of the treadmill to enable running, bench pressing and jaw movements.In addition, the oxygen generator is integrated into the controller, and the water is added to one side of the treadmill. A fitness machine for both a running machine and a bench press device having a true water storage unit for accommodating is proposed so that a plurality of users can use it simultaneously.

However, the conventional aerobic exercise and anaerobic exercise apparatuses are mostly suitable for one type of exercise, and the exercise apparatuses are also suitable for exercise for training a muscle or organ of any part and various kinds of muscles or organs. It is not possible to carry out various kinds of exercise for training or it requires expensive purchase cost and installation place, and has a disadvantage of poor portability.

Therefore, the present invention has been made in view of the problems of the prior art, the object of which is to perform a variety of exercises for the training of various types of muscles and organs and to select the exercise intensity according to the user's fitness and exercise posture To provide a multi-purpose exercise equipment that can be.
