I like Amy D. I have 2 of her other DVDs and I like them. I think she's knowledgeable with a great personality. In spite of that, I found this workout to be very boring. I mean, I was dripping in sweat but I just couldn't see myself reaching for it again and again. It has the dread factor. I don't know how else to explain it...maybe if this were a live class that I attended it would be more exciting but on the DVD it was just boring. I'm glad many others liked it...just wasn't my cup of joe.
