I bought this because I love CArdio Coach. I have every volume except Vol 1. I was really apprehensive before doing this one because Vol 4 is so difficult for me. I LOVED it!!! The first challage has FOUR MINUTE intervals. I did a standing climb for this and really felt it in the glutes. The seconf challenge has short challenges. Each set of challenges is different and I liked that a lot. The music is great and the cooldown music had vocals, which is unusual for CC music. This is my favorite CC workout so far. I will buy anything Sean puts out. He rocks.

Instructor Comments:
Sean is awesome.
