Query: Terrible

Like another reviewer said, the first workout was tolerable and did get your heart rate up...a little bit. But the other two were a waste of time. I'm surprised the FIRM let this pass. I have many FIRM dvds and am usually happy with most of their products, but this one was boring, unimaginative, and slow. Try another dvd first. This is not the best the FIRM has to offer.
