Parkinson's is a debilitating disease that affects a person's movement, strength, and balance, and in many ways is still a mystery to doctors and scientists. One thing that is becoming more clear, however, is that regular physical exercise seems to help slow the progression of the symptoms and delay the effects of the disease. And now a certified trainer, David Zid, and a doctor afflicted with Parkinson's himself, Thomas H. Mallory M.D., have collaborated to create a fitness regimen specifically designed for Parkinson's patients.

The fitness plan is available in the book "Delay the Disease: Exercise and Parkinson's Disease," and part of the proceeds from the sale of the book will go to support the research, development and treatment of Parkinson's.
