You're in SCORELAND to see busty chicks walking and jogging in tight tops. At the same time, their big boobs should fall out of their shirts and go flying in all directions or the exercise class is a waste of time. We instructed Katarina to work-out her tits and include nipple fitness exercises, which stimulate the release of the brain chemical oxytocin, a pleasure hormone that's also released during orgasm as well as pregnancy. For a closing training routine, Katarina was handed this thing called a battery operated muscle stimulator. She asked our photographer if he had any extra batteries on him, just in case she wanted to keep exercising after he stopped taking pictures. You have to wake up pretty early in the morning to keep up with Katarina. Running Time: 18:41.
