Exercise is the only true treatment for Parkinson’s.   We are here to help you FIGHT BACK AGAINST PARKINSON’S DISEASE!

East Tennessee’s Only Gym Dedicated to Fighting Parkinson’s Disease

Research has shown over and over again that exercise is a vital component of combating Parkinson’s disease. It is the only thing that treats the disease – everything else (drugs, surgery, shots, supplements) only mask the symptoms.  Regular exercise can slow, stop, or even reverse the progression Parkinson’s disease.  If your neurologist doesn’t tell you to exercise, get a new neurologist.

Don’t wait for a crisis.  The sooner you start exercising, the sooner you will feeling better.  This is not something you wait to get worse.  Would you wait for your symptoms to get worse to take a drug proven to make you feel better?  Exercise slows the progression of Parkinson’s no matter what stage of PD you are in.
