Also called dive-bombers, this is a more advanced modification of a push-up and takes practice to be proficient.  Start in a pike plank position- feet on the ground, back arched with butt in the air, and hands on ground with arms straight. This position in yoga is sometimes referred as “downward dog”. In a fluid motion, bend elbows to a push up while rolling and scooping back from an arched position to a caved in position until your body is close to the ground’ then straighten your arms and keep back close to ground to end in “upward dog”. Return to original pike position to end the repetition.
