As an actor, producer, and screenwriter, Justin Theroux is undoubtedly one of Hollywood’s most talented triple threats. He’s also one of the most ripped, and has become almost as well known for his shirtless magazine covers as he has his recent filmwork.
Anyone inspired by Theroux’s muscle tone will be happy to know that the actor doesn’t take his workout routine too seriously. Rather, he prefers to work smarter, not harder, and most of his time exercising is spent boxing, an activity he genuinely enjoys.
In this article, we take a closer look atThe Girl on the Train actor’s favorite exercises, typical workout routines, and preferred diet plan.
Justin Theroux is a rarity in Hollywood. Known for his smoldering good looks and subtly powerful presence, he has been working consistently for more than two decades. He appeared early on in films likeCharlie’s Angels: Full Throttle,Mulholland Drive, andZoolander, in the latter of which he is credited simply as “Evil DJ.”
Theroux is also the rare actor who has found success as a producer and screenwriter, too. He is credited as a co-writer on films likeTropic Thunder andIron Man 2.
However, Theroux shot to fame when he was cast as the lead in HBO’s post-rapture drama,The Leftovers. He became a household name in August 2015 when he married A-lister Jennifer Aniston. Though Justin and Jen divorced in September 2017, the two remain friends.
At 50 years old, Theroux stats are:
Height: 5’9” (176 cm)
Weight: 159 lbs (72 kg)
Chest: 43 inches (109 cm)
Biceps: 15.5 inches (39.5 cm)
Waist: 32 inches (81 cm)
Justin Theroux doesn’t obsess about working out. Rather, it is an activity he genuinely enjoys, but limits to just about an hour per day, five days a week. Forty minutes of those hours are spent boxing at his favorite gym, while just about 20 minutes are spent circuit training.
“We stick to the basics,” says Theroux’s trainer about the actor’s workouts.
These “basics” mostly include:
A core exercise that can be done anywhere, without any equipment.
Known also as Kneeling Cable Crunches, Cable Crunches are a weighted variation of crunches that target your abdominal muscles.
The Decline Sit Up is a very effective exercise that targets your core. It requires the use of a Decline Sit Up bench.
To make this exercise more challenging, do as Theroux does and complete the Sit Ups holding a weighted plate over your chest. Though the actor uses a 25- or 45-pound plate, those new to the exercise can begin with a 10-pound weight. As you rise for the Sit Up, simultaneously raise the plate over your head, then lower it as you lower your body.
The Dumbbell Bicep Curl is a great arms exercise that requires the use of two dumbbells.
The Hanging Leg Raise is a challenging exercise that targets the abdominal muscles and the hip flexors. You will need a high bar, like a Pull Up bar, to complete this exercise.
To further challenge yourself, hold your raised position for a few seconds before lowering your legs again.
The Shoulder Lateral Raise is a simple shoulder exercise that uses weights.
Doing squats is an effective way to strength train, especially since they don’t require any equipment and can be done anywhere.
To make this beginner’s exercise more challenging, you can hold a weighted ball above your head as you squat.
The Triceps Press Down is a go-to exercise for those wanting to work on their upper arms. You will need a Cable Machine.
Justin also incorporates push-ups and pull-ups into his workout routine.
According to an interview withMen’s Health, Justin Theroux has stuck to the same workout routine for years. He works out for about one hour a day, five days a week.
Unlike most other actors, Theroux doesn’t do a ton of weight training. Rather, the majority of his hour-long workout is spent boxing. In fact, Theroux calls boxing “essential” to his bodily and mental health, and has made it his primary workout.
After about 40 minutes of boxing with his trainer at Gotham Gym in New York City, Theroux spends just 20 minutes circuit training with timeless, go-to weight-room exercises. Throughout his work-out week, Theroux switches between two circuit routines.
Theroux’s first routine focuses on his core. He completes three sets of about 30 to 40 seconds, and tries to rest the least amount of time as possible between exercises.
Theroux’s second routine focuses on strength and weight training, and is effective for maintaining muscle tone. He completes two to three rounds of the following exercises, with as little rest between exercises as he can manage.
If you are just beginning, then take a rest between exercises if you need to. Just try to keep your rests as short as possible.When Theroux is out of New York City on location, or otherwise can’t make it to the gym, he still works out with the following exercises, all easy to do at home.
Says Theroux, “The beauty of workouts now is that you really just need some rubber bands and a kettle ball and you can set up anywhere.”
Justin Theroux loves boxing -- and according to his trainers, he is very good! The actor chooses to make boxing the core of his workouts, and works with a trainer at the New York-based Gotham Gym.
As Theroux knows, fitness boxing is incredibly beneficial health-wise. It is a great aerobic exercise that blends both cardio and strength training. It’s also an ideal workout for staying lean and maintaining your weight.
Some other benefits of boxing as a workout:
The good news is you don’t need access to Gotham Gym in New York City in order to incorporate boxing into your own workouts.
Simply find a free space in your basement, garage, or bonus room, and gather the following:
If you have access to a training partner, then having punching mitts will make it easy to transport your boxing workout anywhere.
Things to remember when you incorporate boxing into your exercise routine:
Though his ripped body may suggest otherwise, Justin Theroux doesn’t worry too terribly much about sticking to any kind of diet plan.
Rather, Theroux follows a few simple rules for eating as healthy as possible:
Another big key to Theroux’s diet is intermittent fasting.
Lauded by a number of Hollywood stars ranging from Benedict Cumberbatch to Chris Hemsworth, intermittent fasting allows you to eat fewer calories while boosting your metabolism. It’s most frequently used as a tool for weight loss and losing visceral fat, though fasters also report increases in muscle tone and energy levels.
Though there are a number of ways to fast intermittently, Theroux prefers to fast 12 hours of the day. He rarely eats past 7 P.M.Theroux alsoprioritizes quality sleep, which keeps his mind sharp and his body in constant rest and recovery mode.
Actor Justin Theroux is best known for films likeCharlie’s Angels,Mulholland Drive,andZoolander, plus his hit HBO television showThe Leftovers. He is also well regarded for his good looks and ripped body. For the latter, Theroux credits a five-day-a-week workout routine that consists mostly of boxing at his favorite gym in NYC.
To maintain his muscle tone and keep the weight off, Theroux spends just 20 minutes a day on circuit training classic exercises like deadlifts, bicycle crunches, and hanging leg lifts.
