20 Things You Probably Didn't Know About Logan

20. Working Up A Thirst

It goes without saying that Hugh Jackman’s workout routines got more and more intense as the X-Men saga pushed on. He arguably reached his peak in the Wolverine and Days of Future Past, but that does not mean his physique in Logan was anything to scoff at.

However, the means with which he achieved his imposing build were a tad extreme. Before shooting shirtless scenes as the character, Jackman went a full 36-48 hours without drinking water in order to lose water weight and achieve Logan’s strapping but unsettling appearance.

Take into account that this dehydration technique was done alongside the usual strict diet, intensive workouts and long filming days. While the effect was successful, the actor understandably discouraged rookie fitness enthusiasts from trying out the temporarily effective but ultimately harmful workout hack.
