Query: I have bought better ones

I have watched Jackie's Bravo series "Workout" and thought to try her plan since you really don't see all that much exercise going on on the show. It's okay but I have bought better exercise DVD's like Jillian Michaels '30 Day Shred'. I think that Jackie needs to get back to basics and stop believing her own hype.
