Strange about Amazon, I ordered from them as well right when the dvd came out and just checked Collage, and they only have an "add to wish list" button.
I tried out PS5 last night. The only slight negative for me, I like the music in PS4 better, but 5 is a great workout, Ilaria did not disappoint. 5 is just like PS4 regarding intensity. By the end I'm totally sweaty, but I'm not really out of breath. It is a great solid workout, especially when you want cardio, but not the "gasping for air" kind of cardio.
And as usual from her dvds, I have a nice soreness in my back abs and upper arms. Although some of the arm soreness could be from doing Muscle Endurance on Monday.
I really appreciate her attention to good form and her combos were actually quite different than usual, it was nice to have some new punching combos.
If you like PS4 and or like kickboxing in general, this is a great dvd to add to your collection.
