bring your arms out like the letter t and do arm circles-15 in each direction. ALSO If you don't have a foam yoga block--get 2 hardback dictionaries or the equivalent and wrap them with a towel. Then, lay flat on your back with them under your upper spine so that you can hang your head back and open your chest. Then you can bring the arms and head up and do a crunch. keep repeating until you feel better.
