Eagle arm first! Arms wrapped, keep a 90 degree angle so that your arms are parallel to the floor. You will turn and look away from the top arm. Switch sides!

Sit on one of your hands. Turn your chin to the opposite shoulder, and this hand will go behind my head to add some pressure to take advantage of that stretch!
Now we are going to open up the front because of all the texting and computer work. Put your arm at a 90 degree angle in a doorway, and then look up over your shoulder while lunging forward.
