Ouch!

I went to this cardio class at the gym yesterday. When I went up to the instructor and told her I was new to the class, she told me what to expect for the next hour. "This is an interval training class," she said. My thought was great! we will work hard and push ourselves for a few mins. then we will take a couple min break to slow down your heart rates. WRONG!! The whole class we were jumping up and down and running across the floor. Um...I don't think she knows what interval training is!
So today i'm a sad pile of pain. I can barley walk. How sad! So let me just end by saying...OUCH!
