Arm Circles and Side Crunches
Lying on your side, put your top hand out in front of you and then sweep it around in a big slow circle parallel to the floor. After eight circles, go the other way. Be aware of the sensations in your shoulder: don not hurt yourself.
Still on that side, put your top arm on your thigh and do a side crunch: bring your straight, parallel legs up off the mat as you also bring your head and shoulders off the mat, sliding your arm down your leg. Hold and breathe. Relax. Repeat three times.
Turn on your other side and do the circles and crunches.
