Awsome (period). Exercise by Excercise with video and timer. The trainers see me using it and started copying parts of the routine. Cant beat it. I have improved so much with core support and inches off the waist. Anyone knocking either didnt use it or is just stupid. It works, its easy. I have my kids using it. If a 6yr old can do the excersizes then whats your excuse?
