From plank on feet the weight of the fligher is shifted to the bases left leg and the base can take the right leg from the hip. The flyer brings the left leg slowly to the front and side and bents the leg. The base places the right foot on the inner side of the flyers left leg. if the base bents his right leg bit the hooking of the flyer is easier. The weight of the flyer now shifts to the other side so that the base can bring the leg from the hip to the thigh of the flyer.
When both legs are hooked the base bends the legs and thus pushed the flyers upper body upright. The hands release and base straightens the legs to Throne on Feet pose.
