Cupping therapy is a form of alternative medicine in which a local suction is created on the skin with the application of cups heated and or not heated. The one in this video is not heated cups (heated cups sounds painful.) It is supposed to relieve muscle tension, improve blood flow and promote cell repair. He's doing it on her butt because of iliotibial band syndrome, which is when connective tissue rubs against the thighbone. I'm not saying what do you think about butt cupping, lol, because it can be done on various parts of the body, but here's an idea of the cupping therapy/method I'm referring to.
