"As someone who has been an MD for over twenty years, I can tell you that yoga is quite simply the most powerful system of overall health and well-being I have ever seen.  This single comprehensive system can reduce stress, increase flexibility, improve balance, promote strength, heighten cardiovascular conditioning, lower blood pressure, reduce overweight, strengthen bones, prevent injuries, lift mood, improve immune function, increase oxygen supply to the tissues, heighten sexual functioning and fulfillment, foster psychological equanimity, and promote spiritual well-being...and that's only a partial list." Timothy McCall MD, author of 'Yoga as Medicine'.

Don't think that yoga is only for the bendy, fit and thin. If you think that you could NEVER do yoga, then yogo may well be especially good for you.  In fact, it's the people with no experience in yoga who will often make quick progress with health problems. People who find yoga most challenging, think they are terrible at it and have trouble quietening thier minds often have the most to gain from yoga.
