Query: Karen sweats and so will you!

A tough workout not for beginners. Cueing is quick. I found I had to do it about four times before I started getting some of the steps down. I like that the workout seems to go fast because of Karen's "get down to business" attitude. The longest cardio segment is in the beginning, 9:15 minutes, so you know you got the longest one out of the way after it is over. By then, I am very warm and in the zone. The moves are not dancy but I do find this tick-tock move she does a bit difficult. The aerobics alternating with the weights and then abs and butt really makes me feel like I have had a workout from head to toe.
