In an attempt to prove it wasn't a fluke, I got back on the exercycle this morning again. I note that my left knee feels less stiff than it's been -- actually, I don't know that stiff is the right word, it's more a case that my lower left leg feels heavier and harder to lift than my right leg. And the soreness around my right knee also seems to be being reduced.
Ok, better living through exercise.
There will be no exercycle on Thursday and Friday this week in any case, because I have meetings downtown those days that require me to catch a train at 7:30 AM, but I will try not to use that as an excuse to fall off the wagon -- or stationary bike, as the case may be.
