Query: Boring - for Beginners

It's about 44 minutes long and 40 of them you are punching or doing butterflies. There is no real cardio movement. Just, punch and more punch to an airbag that you can even punch hard because; as might as well just use a hanging balloon.I am used too the extreme, ultimate, the best of, cardio work outs by Billy Blank but this one was just too slow for me. I wish someone would of rate it before I bought it.
