It's good to read about the positives of exercise. I had been wondering if having PD might mean that I couldn't or shouldn't exercise.

Nevertheless, I recently started using my old treadmill and I think overall I'm feeling better, except for some leg muscle burn. I have trouble staying upright so I have to use the hand rails and stay aware of my body's relationship with my surroundings. I've noticed that when I turn my eyes to the side I have a tendency to lean, so I've been trying to keep my eyes pointed straight ahead.

I used to run a lot--marathon distances. When I was in my prime, I would run 10 to 20 miles per day. I would run a 10K distance in 40 minutes during my lunch hour and then do another 10 or more miles in the evening. I slowly stopped running as the stiffness and joint pain progressed.

So now I'm finally getting Sinemet, I have relief from the stiffness and pain, and I'm able to work out again. It feels just wonderful. I still love to run. Exercise is good for us in so many ways. I was pleased to note that the muscle memory is still there. Last weekend, after 60 minutes on the treadmill and working up a good sweat, my pulse was 49. For distance runners that's a good thing. The heart learns to pump more blood per beat thus requiring fewer beats per minute. After all these years, the heart muscle still remembers. Amazing.
