This exercise is an excellent progression towards the Handstand pushup , by making the requirements for balance and shoulder strength slightly lower than for the full Handstand pushup .
It still places a lot of strain on your shoulders. If you can't hold this position, you might need to spend more time working on progressions like the Pike pushup and related exercises.
Place your hands on the ground and lean forward with bent-arms, as if you were going to do a Crow pose , except that your knees are not resting on your arms.
Transfer all your weight to your hands and lift your hips up, keeping your hip and knees bent.
Aim for about 90 degree angle at the elbows. Your head should be a few centimeters (or a couple of inches) off the ground.
Form tips
Aim to keep your elbows pointing back rather than outward. This is a slightly more difficult position for your shoulders but is also more stable and will protect them.
Risks
During your first attempts at this exercise you should place a soft object in front of you, in case you faceplant.
