30 Min Focus: Seat & Abs

If your studio is offering this class this month and you like a challenge - take this class! I thought 30 minutes would be quick and easy. After 3 minutes in I looked over at other people with a WTF did I sign up for look on my face. Even instructors taking the class looked like they were dying. I take classes 3-4 times a week and my god I am sore everywhere. If you take it, tell me what you thought!
