Got 7 minutes? Try this.

My sister put me on to this several months back. It's a great little workout that will really work your core strength. So if it's pouring cats & dogs outside and you don't wanna go out and run (gee, that sounds kind of familiar) try this. And who doesn't love Dr. Oz?

I am wondering if Joel Harper is related to Bob (of Biggest Loser fame)? I love Bob's Inside Out series workouts.
