Physical therapy today

I went to the physical therapist out of town for the first time today.  I missed exercising that would include a sitting "step-climber" or a slow walk.  I also need to stretch my muscles.  This would be good for my back.  I spent between 10 minutes on the sitting step and about 5 minutes on doing stretches and tightening in muscles.  So it has been a while since I have done any kind of workout (other than yard work or shopping).  Today, I burned 30 calories and "walked" for 10 minutes at 0.2 miles.  Unless my math is wrong, it is a rather slow 1.2 mph.  Oh well, it is better than nothing.
