I have quite a few DVDs in my mind, like other posts suggested X10 is an amazing cardio/metabolic AND VERY INTENSE workout with so many different premixes from under 30 mins to more than an hour choices, or if you want a strength based workout PYRAMIDS upper and lower body workouts (both in one DVD) and because you already have XTRAIN, these are so different than XTRAIN weight workouts. Body max 2 is really best of the best, because it has excellent cardio, plus abs, plus lower body, PLUS upper body weight work AND IT IS REALLY THE HARDEST AND MOST ADVANCED (and very long [emoji33])workout.
But if I were you, I really agree with KATIE LEE if you can wait and save up and buy Ripped with HIIT series. Because RWH has everything, like heavy weights, cardio, upper/lower body circuits, excellent lower body weight workout, 2 bonus Abs routine and they are so FUN, and soooo many premixes and yes this series is the MOST ADVANCED series!
