The fourth part of Grasp Sparrow’s Tail is Press.
1. From the end of Roll Back, begin to turn waist to face side wall while also beginning to pour weight into right leg. At same time, begin to send fingers of left hand toward side wall with hand coming closer and closer to right hand still in ward off position.
2. As waist turn and weight shift complete (right knee does not extend beyond toe) press left palm into right wrist and finish in 70/30 bow stance.
This movement is led by the waist with a rooting and pressing of the back foot. Hips and shoulders should be square with side wall.
