i've tried lots of cardio work outs and i find that the advanced taebo dvd's or videos are the best. it provides the best all around total body workout. i lose inches in my arms, waist, legs, butt. he even has dvd's that focus on abs or butt or lower half, or upper body but are still cardio. and they're an hr long. takes some working up to and trying several times to feel coordinated. don't give up! it works.
