I listened to rock music and did 4 exercises from the physical therapist. One of them was boring and included 600 (!) leg circles. But music helped and I did it. It took me over 50 minutes. I was not too tired and could have continue but did not have extra time.

So our of 7 exercises, I did 4. I am supposed to do 6. This is not bad. And I am not sure the physical therapist realizes that I would need over an hour to do 6 exercises. I have found that some physical therapists assign more exercises than one realistically has time for.
