'Girls Next Door' twins pick up pole dancing for new workout (VIDEO)

The Girls Next Door twins Karissa and Kristina Shannon were asked to take to pole dancing in Sunday's new episode.

For  the part the girls are playing in a Sofia Coppola movie, the twins were asked to hop on the pole and put together a routine. Easy? Not so much.

Even the twins were stunned with the workout it takes to whittle their bodies around the pole.

"We decided to take pole dancing classes so we could research our role," Karissa said on the show before heading to Evolve Dance Studios to work with pole dancing instructor Jamayca.

After watching the instructor model three of her favorite pole moves, the girls were shocked with the moves.

"Learning how to use the pole was tougher than we though," Kristina said. Adding, "It's like all upper body strength so it was definitely hard for us."

While the twins managed to impress Sophia with their dancing, they aren't the first ones to bring pole dancing to the TV masses.

In a previous season of Girls Next Door when Hef was with girlfriends Holly Madison,Kendra Wilkinson and Bridget Marquardt, Bridget took the cameras on a visit to Crunch gym, where the blondie scored some sweet pole dancing moves in more of a fitness setting.

"It's just another fun way to exercise and get out of the gym and off the treadmill," Bridget said in the on-show interview. Both Bridget and Kendra were instructed by male pole dancing (and speedo wearing) instructor Jeff Costa.

And while Bridget and Kenda have both moved on from the Playboy mansion, they've taken their zany workouts into their new homesteads. Bridget, who installed a trapeze swing in her new house, has said the "trapeze is a great workout" while providing a "vintage style" element to her house.

Playgirl Kendra Wilkinson took the pole from her house to yours when she invented a buy-in-the-box pole to sell online and in studios across America. She told her blog fans, "it is seriously the best workout ever and its so much fun."
