I think it’s fair to say that Hugh Jackman has definitely made the Wolverine character his own, having appeared in eight installments of the X-Men series since his first appearance back in 2000.
However what I find interesting is that Jackman is required to work hard in the gym before each movie in order to bulk up and develop a lot more muscle so that he has the same kind of physique as the actual comic character.
This obviously requires a lot of effort and dedication over the course of several months, and if you watch the video below, you will be able to see what this training involves and the kind of exercises that he most focuses on:
So you will see that he did bodyweight exercises such as clapping push-ups and pull-ups (which are a lot harder than regular push-ups and pull-ups) to strengthen the upper body, as well as squat thrusts and lunges to strengthen the legs.
However he seemed to concentrate mainly on squats and deadlifts, which is understandable because these are two of the most effective mass building exercises that you can do, and will strengthen your whole body.
The only observation I would make is that his form is not very good for either of these two exercises, despite being under the guidance of some professional trainers. So in many ways he was lucky not to sustain a serious injury during his training.
For example, you will see he is really straining at some points during his deadlifts and not using the correct muscles to lift the weight off the floor, which at his age could easily have resulted in a herniated disc.
Furthermore his squat form is even worse because he is not going down far enough on some of his squats, and his knees appear to be in front of his feet at one point, which could potentially have resulted in a knee injury.
Plus he is also cheating on some of his deadlifts because he is bouncing the weight off the floor, and at one point is being assisted by two of his trainers.
Despite all this, however, Hugh Jackman still has to be applauded for his efforts because he managed to get himself in tremendous shape for each of his movies, which is not easy for anyone to do once they are in their 40s.
