Physical therapy 15:00 
At home. With yellow (weaker) Thera-ring.
3 sets each leg of clam shells, scissors, fire hydrant, all holds for about 30 seconds. 3 squats, slightly shorter hold. 1 crab walk.
When I had a sore knee a year (or so?) ago, Kevin had me work on strengthening my glutes. After my knee stopped bothering me, these exercises eventually faded out of my repertoire. With my knees really aching the past few weeks, figured I'd better start doing these.
Afterwards, my left knee really ached for ten minutes.
