I recently bought this DVD as well as Kathy Smith's lift weights to lose weight, and I have to say both are huge disapointments! I am relatively fit and used to exercising but these DVDs do nothing for me - in fact if you could rate them in the negatives I would! The choreography is messy, there are so many people jumping around it is hard to see what you are meant to be doing at any given time. The camera jumps from shot to shot so quickly that a lot of guess work has to be done in order to keep moving! I have had a lot of success with other DVDs like Leslie Sansones Walk away the pounds, and I would have to say that even though they may be monotonous after a while, they are certainly better choreographed and filmed, and all in all a lot more effective which is what counts!
