Come to a straight-arm plank position (also known as tall plank or high plank), hands under the shoulders with fingertips facing forward.
Do one push-up. Keep the arms parallel to the body with elbows grazing the ribcage for your push-ups. You might not be able to come down as low, but you will tone your triceps!
Slide the right hand a few inches so it's below the center of the chest, and lift the left hand to the ceiling, stacking the hips. Keep feet staggered on the side plank to deepen the work.
Dip the hips toward the floor twice. Think six-inch movements down and up with the hips as you dip. For an advanced version, look toward your lifted hand during the hip dips.
Return back to the push-up position, and repeat on left side.
