Great Workout . This is a very fast paced workout. It took a couple of times through to learn the routine. Denise doesn't cue all that well. She's very upbeat and energetic and constantly gives words of encouragement. Most people don't like that about her, but I think she is motivating. You definitely work all muscle groups and you'll be sweating with this workout. I'm tired, but invigorated by the end. I enjoyed this workout a lot
POS
