This push-up variant resembles the image of the myth that ostriches stick their heads in the sand when startled.
Start in a standing position, feet together. Hinge at your hips to touch your toes. You may bend your knees if you can’t touch your toes otherwise. Without moving your feet, walk your hands out 5 hand lengths total and bring the back hand to meet the front. Here is your pike position.
Keeping legs as straight as possible, bend elbows to bring forehead to the ground. Straighten arms to return to pike position. This cycle is one repetition.
