I like combining Zcut cardio workouts with Turbo Fire. I do TF first, then add on one or two workouts from Zcut.
I like the strength one too, but seem to reach for the cardio ones more. They have a lot of body weight stuff, so you still get some strength work.
I have only done the yoga one (or several chapters of) I think twice?
I need to get back to that one. I would have liked a play all option though. Or a remix or longer chapters or something.
