Setup: Lie facedown on the floor with your feet touching a wall behind you and your hands flat on the floor beside your shoulders, head down, spine neutral.
Move: Extend your arms and press up into a plank, then walk your feet quickly up the wall behind you while simultaneously walking your hands toward the wall. Continue until you come into a full handstand with your belly against the wall. Slowly walk your hands back out and your feet back down to the start position.
Tip: Speed is your friend — the quicker you can get your feet moving upward and your center of gravity above you, the easier it will be to get vertical.
