Walk a lot.
Not to be a smartass, but what are you looking for? There's a whole book about how to get healthy and fit, and this site is based on that book. Is there anything in the book that you feel isn't appropriate for the goal that you have? Why do you think that general fitness, given your current starting point, is not enough to meet your goal?
Your question is really vague- What do you want from us!??!
