Hand placement: place hands about 6-12 inches away from the wall and slightly wider than shoulder width apart. Make sure palms are facing forward, or slightly turned out 5-10 degrees.
Kick up into a handstand, with your heels touching the wall. If you have trouble kicking up into the handstand, check out Carl Paoli’s instructions on how to do so: http://gymnasticswod.com/content/kick-handstand
Once you have kicked up, establish a strong, rigid mid-line position.
While maintaining this position, lower yourself until the top of your head touches the floor/mat. Try to keep your elbows at a 45 degree angle as you lower.
Once your head touches the floor, press up with the same tightness you had lowering yourself, until your elbows reach full extension.
