Group exercise & trainer Took several days for back to stop hurting; so less exercise.
Treadmill First did 10 minutes at 3.0 miles/hour by mistake! Returned to 2.5 so could go for longer period of time. May 8 and 9.
Walking & subway Did extensive walking on street during this period. Decided need to give myself credit for taking subway as an exercise since have to climb stairs every time.
