Description

{BARBELL LAYING TYPE-SAFETY HEALTH EQUIPMENT}

The present invention relates to a fitness machine, and more particularly, to a fitness machine, more specifically, a barbell used for a barbell exercise, which is a main movement during a weight training exercise, can be safely stored in a fitness machine itself, Thereby improving the space utilization and usability of the barbell-type safety health apparatus.

Generally, the fitness apparatus is installed in the room to train the body. Such a fitness apparatus is different according to each part of the body, and the shape and function of the fitness apparatus are different according to the region to be trained.

Weight Traning is a representative anaerobic exercise that lifts heavy objects and stimulates muscles to strengthen muscle strength. Weight training is becoming more popular as interest in health and body increases.

Weight training such as barbell, barbell, and dumbbell is required for weight training. In particular, in weight training, the main movement, the barbell movement, is selected by selecting a barbell disc of various weights, and attaching the barbell to the barbell to train the muscle.

When performing this barbell exercise, the best way is to exercise while being assisted by an assistant. If you exercise with a pair of exercises, your assistant will come in with the exercise It is possible to maximize the exercise effect.

At this time, according to the health report, athletes, such as a health coach, may be able to increase their muscle mass much faster if they exercise a little more. So, many health trainers are recommending exercise in pairs.

However, there are not many people who work with assistants when they actually go to the gym, because it is difficult to match each other's time, and because they have their own exercise schedule, it is difficult to exercise with a pair of two people. It is a reality.

As an alternative to this, a number of techniques have been disclosed for a fitness instrument that is powered or assisted with motorized muscle movement such as weight training. In other words, the technique of electromynging or exercising muscle movements should make the physical athlete feel natural and gentle with the help of the device, as if a professional trainer is helping.

However, such a fitness instrument is required to have various electronic components including a sensor for precise control, so that the configuration becomes complicated and the cost of a product of a fitness instrument increases.

On the other hand, in order to perform more systematic training, heavy materials must be detached and used. In general, in the case of the barbell plate, there is a problem that the plate is piled up on one side or left in a state of being attached to the barbell so that it is not easy to manage. Not only the cost increases but also the space is limited.
