Gloves with glue in the palm can be bought in shops selling labor insurance supplies. This kind of gloves will be very astringent when held on the horizontal bar, and their hands will not be very painful. Be careful not to slip out of the glove when holding the lever. It is best to tighten the wrist part of the glove by yourself.
In fact, people who hang the horizontal bar will hurt, which must be tolerated. Even if there is a palm guard worn by a professional gymnast, the hand will still hurt and cocoon. When I first started practicing, all the meat on my hands was worn off. When you really have a cocoon on your hand, it won't hurt very much. Of course, you will get used to the pain then.
If you plan to exercise regularly, you can buy a pair of fitness gloves that only show your fingers. Of course, you can do without it, but if you exercise regularly, your hands will grind out cocoons.
