Pauline Potter of Sacramento, California, holds the Guinness World Records title of World’s Heaviest Living Woman. She accepted the title because she “was tired of being this size,” and wanted to get help.

The then-643-pound 47-year-old got help alright, but from an unconventional source: her ex-husband Alex.

After he saw photos of her in Guinness World Records last year, Alex got back in touch and they’ve been getting down and trimming down ever since with “marathon sex sessions.”

“I can’t move much in bed, but I burn 500 calories a session-it’s great exercise just jiggling around,” Potter told Closer magazine.

Potter says their “sexercise” sessions occur multiple times a day, and she’s already lost dozens of pounds on her way to a target weight of 532. [Gawker]
