When I first started biking after my diagnosis of Parkinson’s, I didn’t know how much was right.
Looking at the news reports on the Web about Dr. Jay Alberts’ experiments, I decided to try to get to those levels. It took time. Initially I had trouble sustaining 80 rpm for even a half hour. But perseverance paid and within a month I was regularly doing 40 minutes at at least 80 rpm. And I was able to do it daily, which pleased me.
Today I have worked up to 55 minutes total, with 5 minutes of warm up in the beginning and 5 minutes of cool down at the end, trying to do 100 rpm in the middle 45 minutes.
And I feel good.
