I just love this video. It has HIIT and UB strength mixed every other exercise, 2 rounds. One of my very favorites. I've come back to it a few times. Probably my favorite 5/5 difficulty!! They call it "cardio" I call it HIIT. I was huffing and puffing at the end for sure!! Anybody else try this one?
