I'm going to the gym three times a week now, and my gait when I'm walking distances is getting closer to normal. I do have to exercise every day to stretch out the knees, if I'm not at the gym (where I stick pretty exclusively to the recumbent bike; my next move will be to add laps in the pool.)

I watch others workout from my position on the bike up on the balcony overlooking the central equipment area. Every so often I see someone coming in for a rehab kind of workout; that was me for the first few times I was in. Now it's just for the exercise.
