Take a look at the manufacturing level of this fitness equipment, and you can check the authenticity. Before installing the equipment, be sure to check whether the screws are loose and whether the pull rod is firm in advance. Whether the handle of the knife and sword is loose with the blade. Injuries and accidents caused by sudden changes in equipment and broken swords occur from time to time, so don't be careless. It is a routine safety measure to have someone around to protect you when practicing on the equipment. The so-called protection means that when the practitioner makes mistakes in practice or changes in equipment may cause injuries to the practitioner, others take decisive and powerful measures to get him out of dangerous actions, which is protection. Protection is a powerful measure to prevent injury accidents. Therefore, I hope that all people engaged in equipment practice will never try to be brave and never practice alone.
