The muscles in my left leg were tense today, almost all of them it seemed. Maybe all of that pulling was aggravating the soft tissues around the joint. Although I have been rather downbeat the physio persuaded me that there was improvement: the weekend's walks had made my knee a bit sore but two runs didn't cause any problems. I had to agree that is progress, albeit apparently slight.
A little later it was time for the swimming class. I worked hard to look after the stroke especially the finish. After a few weeks of chaos I suspect that I've got the beginning of the stroke more or less right so that there is no forward movement of my hand whilst in the water.
