When you think about muscular bodies in movies and pop culture, there are a few standouts that immediately come to mind. Brad Pitt in Fight Club, Gerard Butler in 300, Hugh Jackman as Wolverine in the X-Men series, and of course, The Rock in anything. Then there's the rare non-action movie role that prized muscles for straight-up sex appeal: Channing Tatum as Magic Mike.<br /><br />Unlike other films that take actors from all types of backgrounds and force them to play outside of their comfort zones, casting Tatum in Magic Mike was an authentic move. <br /><br />By the time the first movie came out in 2012, however, Tatum was already a successful actor. He might have had the moves to play a young stud dancer, but the body to match was going to take some work. Tatum linked up with trainer Arin Babian, who knew he was in for a challenge when he met with Tatum to train for the first time.
