$5! What a deal! The Sculpt tape is a pretty good total body weight workout (I assume you have dumbbells at home?), so you don't need to do the circuit training at all. It wears me out; there is no way I could do both! If you've been lifting, you'll probably find that after learning the moves you can go right to 3/4 for more intensity. I did. If you want to continue circuits, you could just substitute Sculpt for one or more of the days.
