Ha! It's a lot easier to do. I think Cardio and Weights is about the easiest Cathe tape I've seen, but it's really fun, and certainly not a waste of time. I use it on days when I'm tired or just can't face anything grueling.
CircuitMax is one of the toughest cardio tapes in my opinion. I think it's as tough as IMax, or maybe a tiny bit easier.
