Ricki Lake shaped up during her time on Dancing With the Stars -- and so far, she's kept it off!

That's because the 43-year-old talk show host uses the Bar Method, which burns fat and elongates muscles.

Bar Method SoHo owner Kristin Kelleher recently invited Us Weekly to her New York City studio where she demonstrated a thigh exercise called the "parallel thigh."

"It is designed to elongate, narrow and tone your quads," Kelleher explained. "Because we're working a large muscle group, you will also burn a lot of fat and calories."

Advised Kelleher: "Do this method along with other bar method exercises three to five times a week to achieve fast results."
