I have Jillian's Kickbox video. It was a waste of money. She does "laugh wildly" as someone said, she wastes time telling her crew to get with it, and she doesn't stay with the beat. You can definitely do better. The only plus is that it is a 20 minute workout for when you're in a crunch. But I'd rather just abbreviate a Cathe video.
