10. Hugh Jackman: The X-Men Movies
Source: moviecricket
In order for him to get in the berserker mindset of Wolverine in the X-Men movies, Hugh Jackman used to take cold-as-hell showers before he could go on set. However, his body seems as if he has been bulking up with every new movie that he features in. For The movie Wolverine, this jacked actor hooked up with David Kingsbury and they worked for long days, at times only getting less than 5 hours of sleep. Workouts started first thing in the morning and included a strict, clean diet. Carb-cycling was extremely important to achieve maximum results for this instense, muscle building project in addition to a well-timed eating plan.
