A regular exercise routine can help you maintain your abilities, strengthen your muscles, increase mobility in your joints and build up your general health and fitness.
Recent research in animal models of Parkinson's has shown that exercise seems to protect the dopamine-producing nerve cells that are lost in Parkinson's, helping them work better and survive for longer.
This could potentially slow down the progression of Parkinson's - something no current treatment can do.
Research into the effect of exercise in people with Parkinson's has shown some promising results, including improvements in mobility and balance. But as yet, the long-term benefits of exercise are not fully understood.
Researchers are also looking at different types of exercise, including t'ai chi, tango dancing, gym training and hydrotherapy.
