1, hula hoop is a simple waist movement, and the amount of exercise is small, so it is not realistic to achieve slimming effect by this movement alone. Moreover, the twisting and swaying part of the hula hoop is just at the junction of the thoracolumbar spine. When the spine is excessively twisted or the abdominal pressure suddenly increases, the pressure in the spinal canal may suddenly change, leading to the rupture of blood vessels.
