I love the exercises when I'm having a good day. RSD is in my right arm/hand and is stage 1 so I put my icepacks on and can do a few things: soccer, penguins, lunge. I can't do it very long before my arm gets absolutely huge, dark and incredibly hot. It messes me up pretty badly for most of the day, even when I keep my arm elevated on the back of a chair with lots of pillows. So I don't do it anywhere near as much as I'd like to.
