i've had this set for several months and i still use it 2-3x's a week. the "cardio" portion involves arm swings (fun & provide some toning), lunges (get the heart rate up) & little hops. this would be do-able for a beginner to advanced. mariel proves to be a great teacher and she has great chemistry with rodney yee. my only kaveat is that i wish there were more core work and some hip openers. this would be a good addition to a current practice but i don't think i would rely soley on this. overall a good solid package.
