The Palm Spring
Stand at a little distance from a wall with your face toward it and leaning forward until you are able to place the palm of your hand quite flat on the wall; you must then take a spring from the hand and recover your upright position without moving either of your feet. It is better to practice it first with the feet at a little distance only from the wall, increasing the space as you gradually attain greater proficiency in the exercise.
