FINISH: When you feel stable with your right leg raised, raise the left arm up in front, stopping when it is horizontal and hip level. Hold this position by tightening all the muscles in your abs, butt and back. Raise the arm high enough to feel your shoulder blade flatten closer to your ribs, but do not raise your hand above your head. Look down and tuck your chin in to your neck, but avoid dropping your head below your shoulders. Keep all body parts in a straight line. Breathe normally. Then lower and repeat. Then switch sides.
Common Error: Over-arching the back when you raise your arm and leg
Fit Fix: Avoid making a C shape with your spine when your lift your arm. Keep your abs tight and your spine stable.
