Robert Pattinson’s jawline is one of the most recognizable and discussed features of his face. Whether he’s flashing a smile or keeping a menacing expression, the 27-year-old actor’s prominent cheekbones and strong jawline have drawn countless memes, comparisons, and (of course) Twitter fights.

But how exactly does Pattinson work out his jawline? Is there a specific routine he follows to shape and define it?

As it turns out, the actor has an extensive exercise routine that he follows to shape and define his jawline. And it’s not your usual everyday exercise regimen. (But then again, not everything about Pattinson is usual.)

Let’s take a closer look at his workout routine so you can get the most out of your exercises whether you’re trying to define yours or just want to be able to better understand Pattinson’s exercises.

Explosive Punching And Weight Training

The starting point of Pattinson’s workout regimen is his boxing. The actor’s trainer, John Watson, confirmed to Women’s Health that the Twilight Saga (specifically, the third movie in the series, Dark Shadows) was the beginning of his love for boxing. (In the movie, Pattinson’s character, Edward Cullen, teaches the art of self-defense to a group of young women.)

“He started boxing because he wanted to be able to defend himself. He did a lot of research and found that a lot of the techniques and moves are the same in real life as in the movies,” Watson told Women’s Health. “So he decided to try it out. He did it for about a year and then went back to doing martial arts, which he felt was more useful in real life.”

While boxing is a great choice for developing upper body strength, it’s also a full-body workout, which means you’re using many muscles. So not only will you be working your jaw, but you’ll be strengthening your entire body, especially your arms, legs, and core. (Not to mention the fact that hitting another human being with a punch full of force actually feels good.)

But the benefits of joining a boxing gym don’t stop there. Another great thing about punching is that it gets your muscles moving and switching roles, which helps with cardio as well. (You’re not constantly just standing or sitting still. Instead, you’re constantly moving around while participating in a sport that requires your full attention.)

Pattinson takes this idea one step further by incorporating weight training into his workout regimen. The actor has a series of brutal squat workouts where he squats with very heavy weights. (Not surprisingly, these squats are also a great way to tighten and define your quads, as well as strengthen your legs.)

The intensity of these workouts is such that you’re not going to feel like you’re easing into any sort of routine. In fact, I’d call them more brutal than anything else. In one workout, he did an overhead squat with a weight that was almost as heavy as he was. (Try doing an overhead squat with a 50-pound weight if you have an average build. This exercise is not for the faint of heart.) These workouts are so effective because they work all of the muscles in your body, from your quads and hamstrings to your arms and core. In addition, all of this activity also gets your cardio pumping as well.

Granville Deathrays Workout

Pattinson also does a lot of running. A large part of his workout routine is fueled by his love for fast cars and driving. (The actor has a garage full of exotic cars, from which he occasionally drives at high speeds.) He does this not only for the fun of it but because he feels that running helps him clear his head and think more straight.)

So instead of doing his regular gym workouts after a tough day at work, he often goes for a drive or sits in his garage working out.

One of the best things about this routine is that it forces you to leave your comfort zone. A lot of times, when you get bored of your regular gym routine, you don’t have the motivation to go outside and run. Doing this workout helps build that motivation. (And for those of you who are not into cars or driving, there’s always the option of putting the pedal to the metal on a bike or walking briskly to work.)

The other great thing about this workout is that it gets you moving outdoors, which is great for your health. (The fresh air is good for you. It clears your head and gets your lungs working hard.) By doing this workout outdoors, you’re also avoiding the overheating that often happens in the summertime when you work out indoors. (Try swimming outdoors instead of in the pool if you’re not used to the heat.)

How To Properly Perform A Chin-up

If you’re looking to define your upper arms, you can’t go wrong with a chin-up. This is one of the kingpins of arm workouts. (It’s also one of the most effective ways to build your mental toughness and discipline.)

To do a proper chin-up, you must first tie the belt of your bathing suit properly. (It should be snug but not uncomfortable.) You should also do regular stretches before starting any workout program, especially your arms. (This will help prevent strain and discomfort.)

Once you’ve got everything set up, it’s time to plank. Place one hand on top of a weight bench and push your body off of the ground. (Your body should be in a straight line from head to foot.) When you plank, you’re working your arms and shoulders hard. (This is one of the most effective ways to build up arm strength.)

Once you’ve got your arms warmed up, it’s time to move on to the actual workout. Start by doing arm curls, working your biceps and triceps. (These are the muscles that you flex when you raise your arm in front of your face. So it’s a great way to work them.)

Once you’ve got your arms worked out, it’s time for the legs. Start by doing squats with your hands behind your back, like a zombie. (These are a great way to strengthen your legs and build up your thigh muscle. Practice these squats with little weights if you’re starting out, and make sure to wipe down your equipment after every use so that it doesn’t get creaky and noisy.)

Moving on from the legs, it’s time for the final muscle of the day: the traps. Start by sitting down with your legs in front of you. (This is a great way to get the blood flowing to your arms and chest.) Extend your arms in front of you and take a deep breath. (As you do this, your traps will be fully engaged.)

While this may seem like a lot of effort to define your jawline, the truth is that it’s a very effective workout routine. Not only does it help build overall body strength, but it also forces you to work out in a way that feels challenging but don’t give you enough incentive to quit. (He may call it quits after the first set, but you know he’ll be back for more.) This is why you should consider trying this workout out, whether you’re interested in defining your jawline or just want to get into shape.
