hit the trainer (which dh kindly moved into the house from the garage, set it up right under an ac vent and bought a table fan for as well- he's good guy) today for an hour. Didn't push it very hard, kept the cadence at 60-65, worked up a slight sweat, legs felt ok but the arms and shoulders are definitely less than happy. It feels like my entire posture and position have changed but that may be just as much mental re-imaging as actual physical change. I will try and do a little every day and see how it goes.

Thank you all for your support.
