How To Get Karina's Flat Tummy Six-Pack With One Cheap Exercise Device

Dancing with the Stars' Karina Smirnoff has an incredible body. And she has worked very hard on staying slim and sexy through hours and hours of dancing. Most recently, she showed it all off inside the pages of Playboy magazine.

What fascinated us, is this little beauty tidbit by the very talented DWTS pro:

Karina Smirnoff has a little exercise tip that will help you flatten your tummy and build toward an envious six-pack. And she does this with one, cheap and simple exercise device:

The Dual Ab Wheel by Valeo ($11.56, on SALE at amazon.com). That's right---for less than $12, you are getting a solid piece of gym equipment that really works. Karina recently told OK magazine that she uses her Ab Wheel first thing in the A.M. to help wake her up.

"It's really, really hard!" she admits. "The first time, I could only do 5 or 10, but it's a pretty awesome wokrout. It feels a little like torture but then after, when you see the results, you're like, 'Oh, hello!"

So, how exactly does this thing work?

You are rolling out away from your chest. To use it, simply get on all fours, grab hold of the handles, and glide the wheels back and forth across the floor.

But, not as easy as it sounds.

This little gizmo requires patience and effort.

The Dual Ab Wheel by Valeo features two sturdy and durable plastic handles. It has a comfortable grip for easy rolling. And it's cushioned with rubber foam for easy handling. There are two non-skid wheels for stability. And it's super for toning abs, shoulders, arms and back.

The way we see it, if it's good enough for a professional dancer like Karina Smirnoff, then it's a well-made product that really works.
