Opening up about his training routine

In a recent interview with On Demand Entertainment, Pattinson said he learned to embrace the process of getting in superhero shape for his comic book film debut, and said he started to enjoy training once he passed “over the six week mark”.

He previously criticised Hollywood for expecting male action stars to transform their body for roles

“It’s all about pushing boundaries and building up to a point where you know you can do justice to the physicality required,” Pattinson said. “Taking on a full physical transformation as well feels even more exciting.”

His training routine included body weight workouts, weight training and boxing drills

He previously said his gym training focused on cardio, body weight and weightlifting circuits, according to Healthy For Men.

His circuit training included:

• Five minutes of cardio to start.

• Bicycle crunches – a core workout where you lie on your side with your knees bent at a right angle, and curl your upper body, lifting shoulders a few inches off the floor.

• Dumbbell side bends – a full body workout where you slowly lower a dumbbell along your leg towards your knee, then lift the dumbbell and bend your upper body in the other direction.

• Double crunches – a core workout where you lie on your back with bent knees and bring your knees towards your chest as you crunch your torso up to meet them.

• Superman holds – a core and back workout where you lie on your back with bent knees and bring your knees toward your chest as you crunch your torso up to meet them.

He did a lot of boxing when he was not in the gym

Pattinson said he also did a lot of boxing when he was not doing his typical gym workout, which can improve cardio and build upper-body strength. Pattinson’s outdoor workouts involved long-distance running and military sandbag workouts. Pattinson previously told Healthy For Men that he went on five to 10 km (three to six mile) runs four times per week to build up his cardio and endurance.

Pattinson also said he did a military-style sandbag workout on the beach. The workout involves doing motions like lunges, squats and sprints while holding a heavy bag of sand for added resistance.

He also had to follow a strict diet to get the perfect body

Pattinson previously said he cut back on alcohol, processed meat and fried food to build a superhero physique. In a recent interview, he shared that his diet included so much fish he got tired of eating it.

“I never want to see a piece of white fish with just lemon on it ever again,” he told On Demand Entertainment.

Fish is a common staple on muscle-building diets because it’s a great source of healthy fats and packs a ton of protein. However, it can get tedious – Dwayne “The Rock” Johnson said he’s been eating salmon for years despite being tired of it because of the health benefits.

“I hate salmon, I have salmon out of my ears. But it’s a great fish in terms of health and fitness,” Johnson told Delish.

Previously, Pattinson also shared he was eating foods like oatmeal with protein powder and canned tuna, which are high-protein and convenient, but bland, Insider’s previously reported.

Pattinson also previously said he wasn’t working out for the role of Batman – which he later revealed was a joke. Between his diet, intense training and filming schedule, the star said he was completely exhausted by the film’s completion.
