I have all the biggest loser workout DVD's and knew I'd like this one once I saw that a new one was coming out. Started the workout and very good, makes up wanna give up at times, but like Jillian said "You wanna be skinny or fat, shut up and do it?!" Something like that. And when she says that I just keep on going. She's also very funny in this DVD, buy it and you'll know what I mean.
