Principle of horizontal bar on door
The horizontal bar on the door is a kind of family fitness equipment that can be installed on the door frame, which originated in the United States. Using the ingenious mechanics principle and the weight of the body to fix the horizontal bar, there is no modification or damage to the door frame, because the real stress point is not the door frame, but the wall.
There is a harness in the horizontal bar on the door that can adjust the length, and the length can be rotated and extended to both ends. Put it on the door frame, rotate it to both ends, and rely on the huge friction between the high-density black rubber ring and the door frame or wall to generate sufficient supporting force. The outer diameter of horizontal rod, the wall thickness of steel pipe and the material of ring pad play a decisive role in safety.
The most common movement of the door horizontal bar is pull-ups, which is a hanging strength exercise to overcome its own weight. It requires a certain grip strength, upper limb strength and shoulder strap strength, which can be accomplished by overcoming its own weight. Can effectively improve the upper limb suspension strength, shoulder strap strength and grip strength. Pull-ups are calculated according to the number of times the action specification is completed.

Pull-ups are pure upper limb strength quality exercises with simple technical requirements. Practitioners jump up, hold the bar with both hands, and hang their hands shoulder-width straight; Pull-ups with both arms at the same time, and lift the lower barra beyond the upper edge of the bar once.
Pull-ups have a certain effect on height, and latissimus dorsi is one of the key training parts for bodybuilders. Its development has a lot to do with bodybuilding. In other words, when the latissimus dorsi is rich and developed, the whole back looks like a "V". There are many well-developed training methods for latissimus dorsi and trapezius, teres major, teres minor, rhomboid and infraspinatus.
Generally speaking, if you have more than 15 pull-ups at a time, you can try to practice with a belt or rope tied with heavy objects or a barbell. Some people like to hang heavy things around their waists, while others are used to tying them around their ankles. However, there are two points to be reminded. First, the weight should be appropriate; The second is to pay attention to safety.
