Workout kicked my butt

I was emailed this website and I did the beginner and man I guess I'm way out of shape!! heres the page you can choose 3 different levels just thought I'd share http://health.discovery.com/beyond/player.html?playerId=2194 75126&categoryId=219564258&lineupId=293829516

Stacy, any workout that whoops your butt, and pushes you beyond what you think you are capable of is a great workout!  As long as it doesn't push you off of a cliff.   I love, love, love, Dr. Oz!  I just wish I could lose weight on a low fat diet, but that doesn't work with my metabolism. I hope you make it up to the third level and end up kicking level three's Butt! Mary
