Handstand with 3 fingers support

Also known as: Handstand with one-arm support (3 fingers).

Technique

From a stable Handstand, begin by shifting the gaze to the base hand that will support the majority of your weight. The gaze should be around the first knuckle of the thumb or index finger, but your unique focal point may be slightly different.
Next, create a very small diagonal with the hips. Focus on keeping the thighs engaged and squeezed toward each other. The diagonal of the hips should match the diagonal angle of the shoulders, with the opposite hip above the base hand.
The diagonal hips should create a sensation of more weight in the base hand. Push the base hand into the floor hard to get a bit more Shoulder flexion backward and Shoulder elevation. Think about the shoulder pushing high up to touch the ear or chin. This additional push will straighten the spine and allow the fingers of the supporting hand to tent up, up until only 3 fingertips are touching the ground.
Imagine a straight line of force between the floor, hand, shoulder, and sacral region (or tailbone).

Do not try lifting the support hand directly. The tenting of the support hand should primarily come as a necessary reaction to the Shoulder elevation on the base hand.
