Place two Handstand block by the wall, slightly wider than your usual Handstand width . Begin in a Chest-to-wall handstand with the hands inside of the blocks. Only the pointed toes should ever be in contact with the wall.
Keep the legs squeezed tightly together the entire duration of the exercise. Do not let the ribs flare out, keep the glutes fairly tight, and generally think about full body tension the entire time.
Tilt the hips to create a diagonal and push through the base hand (the hand on the same side as the lower leg) to elevate the shoulder towards the ear. Tent the fingers of the support hand.
As controlled as possible, lift the support hand and quickly grab the block. Slide the block in without moving the rest of the body. Maintain the slightly tilted straight Handstand position.
Shift the hips slightly over the hand on the block so that the center of mass is over the block hand, which now becomes the base hand.
Push very hard through the hand on the block to elevate the shoulder. This will require additional strength as opposed to the floor shift. Once the support hand on the ground is tented and stable, pick it up to quickly grab the second block. Return to a stable neutral straight position.
Shift the hips to create a diagonal over one block. Once the weight is mostly on one hand, slide the block of the support hand to the side and quickly place the support hand on the floor.
Shift the weight into the hand on the floor shifting the hips over this arm. The shoulder should already be elevated and pushed high in this position.
Once the weight is mostly on the hand on the floor, slide the other block out to the side and return the other hand to the floor. Stabilize the neutral position.
