Levi Johnston’s ‘Playgirl’ Workout

Levi Johnston is back in Alaska after seven days traveling around the lower 48 states, including a visit to the ET studio, and despite his war of words with Sarah Palin, the 19-year-old says that there is no drama with Bristol Palin about spending time with their ten-month-old son, Tripp. Now, let the Playgirl workout begin!

Levi is prepping for a nude layout photo shoot in Playgirl, and he's got a tough personal trainer to get him in tip-top shape. Sorry, Levi – no bacon cheeseburgers!

"The more you come to the gym, the more you see results," says Levi.
