Query: Not really for beginners

This is NOT a beginners workout. Be a LITTLE in shape before you try it. I've done lots of Jillian Micheal's DVDs and like Bob SO much more. His attitude pushed me to keep going, and that's huge for me. I hate working out.He kept me guessing as to what was coming next, but all the moves were ones I could just jump in with - not ones I had to study before trying. He had a good long warm-up and a good cooldown, which is something I don't see often in workout DVDs.After, I feel twitchy and exhausted, like I had an awesome workout, but not like I hurt myself in the process. I feel like I'll be able to do it again tomorrow (even though I'm sure it'll be a little harder to get through). I would definitely recommend to anyone!
