Most basic adult courses start out real slow. If you find you bounce back quickly, the more to advanced beginner classes.
If you're out of shape, get exercising. Bike or swim to build up aerobic capacity. Stretch to help with the muscles. Etc.
Is where you live a problem? Do you know of any schools in the area? Any questions, post another message.
