I find walking does it for me. In fact I just changed my route, I was just going around the neighborhood, which is mostly flat, with one street that's a really steep incline, and decided to just go up and down that street (I usually bisect it and take side streets so I only was going up the incline at the beginning and end of my walk._ I went up and down it two times, same distance as my other route, and OMG, what a workout on the legs! But I feel great!
