It's like the class calls me to get over there! It works every part of my body without the kind of impact that feels damaging. The teacher Richard seems to have eyes all around his head. He takes great care in the students. He notices form and I'm amazed how he doesn't miss anything no matter how large the class is and everyone is being looked after by him to secure good form. CARDIO BARRE® is great for cardio, great for stretching, great for sculpting, and great for what feels like, to me, ... every inch of my body. I have seen changes already and I look forward to the next class!
