Kelly Ripa And Jimmy Fallon Get Fit With Orange Sauna Shorts On 'Late Night' (VIDEO)

When Kelly Ripa dropped by "Late Night," Jimmy Fallon couldn't help but bring up how incredibly in shape the "Live" host is. In fact, he found a fitness tool he wanted to try out with her: sauna shorts. Of course, Ripa was game, and it was only a moment before the two of them looked absolutely ridiculous with the shorts pulled up over their clothing.

“We should order pizza and wear these," Ripa suggested. "One will, like, take away the effects of the other.”

“It’s almost like you can’t even tell we’re wearing them," Jimmy said of the bright orange shorts. But the two stayed in the shorts for the rest of the time Ripa was on the show, including during the game of Pictionary they played afterward. Perhaps it was the shorts, but Ripa became obsessed with one specific part of the human body, drawing them pretty much every time.

“Kelly, stop drawing butts! Stop drawing that on the show!” Fallon chastised her. He transformed her butt into a face, to keep things family-friendly. Maybe she was getting too hot in those shorts!

The sauna shorts retail for around $30, and are designed to increase perspiration to help the wearer lose excess water weight in the target areas of the abdomen, waist, back and hips. Ripa's trainer has an even cheaper holiday tip for losing weight. Anna Kaiser told Glamour magazine that the secret to Ripa's fit fame is the number four. "Work out four times a week throughout the holiday season and you'll be able to enjoy those holiday goodies (within reason!) without gaining weight," the magazine reports.
