Besides kickboxing and walking what are some low impact cardio workouts out there that does not overtax the quads?  (ie, no step).  I do not belong to a gym, so cardio machines and swimming would be out.  I'm looking for dvd or youtube workouts.  I can't seem to find anything that is not dancy choreography or that is not labeled beginner.  Thanks!
