Start in a stable Straddle handstand position. Begin by tilting the hips to shift your weight into one hand.
Since we are not holding the One-arm handstand for this drill, the next part goes very quickly. Push through the base hand to elevate the shoulder and take even more weight off the support hand. At the same time, lift the support hand and quickly tap the shoulder on the same side of the body. Quickly return the support hand and remove the tilt of the hips to return to a neutral position.
A good goal for shoulder taps is 10 alternating repetitions.
