I started with Walk Away the Pounds by Leslie Sansone. It's a great at home walking program that can be ramped up or scaled down. You'll probably get a lot of suggestions...Remember, find something that is fun and that you'll do.
You won't keep going if you hate doing it every day. The best exercise is the exercise you'll commit to doing. Good luck in your search.
