Hold one dumbbell in each hand, place the dumbbells on the floor with one hand directly under each shoulder and the legs straight out behind about shoulder-width apart. Start with the elbows bent and the chest down at the dumbbells. Keep the body straight and flat while pushing the arms into the dumbbells to straighten them into the top of the push up position.  At the top of the push-up, press the feet into the ground and pull the right hand up to bring weight the chest. Keep the elbow close to the rib cage. Slowly lower the weight to the floor before pulling the left hand up toward the side of the trunk. After doing a row with each arm, slowly lower the body to the floor for the next push up.
