In the past, many people used to keep fit with a waist trainer. It felt great to sweat profusely while using it, but the next day, early in the morning, I found that the muscles on both sides of my waist were sore. When I lifted up my clothes, I saw that there were blue and purple bruises.

   With the new generation of extremely flexible hula hoops, your worries can be swept away! After use, simply wind it up, and a large circle becomes two, three, or even four small circles stacked together, taking up no space at all. Moreover, unlike traditional hula hoops, they are not hard, and they will not cause harm to the body!
