Spin up
A Spin up is a Ditangquan technique of Wushu similar to the kip up, where the body is lifted from a lying position to a standing position. The main difference to the kip up is the momentum is generated with a circular leg movement in conjunction with the torso twisting, weight shifting to the upper body and then the hands push off the ground, thus achieving elevation of the entire body. The spin up is also variously called a Star kip up, Black Dragon, Mini-Mill and 180 kip up.
