Instructions
Begin by placing an exercise box in position firmly on the ground.
Get into a push-up position, with the soles of your feet against the side of the box.
One at a time, place each foot on top of the box to assume a decline push-up position.
Walking backwards with your hands, begin to drive your glutes upwards.
Keeping your back engaged, and your arms straight, aim to reach the hold position in which your upper body is fully vertical.
Hold this position for the designated time.
