What if you can't walk for 30 min. due to other physical limitations such as back problems? There is no mention of breaking up the 30 min. into 10 or 15 min. workouts. You make it sound as though you must do a heavy 20 min. or a 30 min. workout to be effective. That just discourages those of us who can't, and we wonder then why even bother.
