Sounds good to me, but I'm sure others will follow with more comprehensive comments soon. Keep in mind that adding muscle (even lean muscle) helps with burning fat. Walks and bike rides are great ways to get the heart rate up while not actually *feeling* like you're exercising just for the sake of exercising. Do you play any sports? A pick-up game of basketball with friends, touch football in the park or some soccer might also help to incorporate movement without the "exercise" stigma. Have any dogs? I have two and they're great to exercise with. =) A game of chase in the park is always good.
