Thanks to Jimmy Kimmel, there may be a new fitness craze taking Hollywood by storm: Hottie Body Hump Club.

"You don't get a body like this from sitting behind a desk with your pants undone," Kimmel, 43, jokes. "Here in Hollywood, being in shape is more important than being alive."

The ABC late night host enlisted the help of super-fit starlets Scarlett Johansson, 26, Jessica Biel, 28, Sofia Vergara, 38, Lindsay Lohan, 24, Jessica Alba, 29, Eva Longoria, 35, Emily Blunt, 28, Minka Kelly, 30, and Kelly Ripa, 40, to promote his faux workout routine (watch above).

"The Jimmy K program is so affordable it's practically a steal," Kimmel promises.

"Allegedly," Lohan adds.
