Jeremy Allen White has sent the internet wild with his new ad campaign, leaving fans wondering how he got so big.
According to a recent interview, he used ancient Greek training to get him in shape.
The Bear star, 32, has committed to his role in The Iron Claw, which tells the story of wrestling legends the Von Erich brothers.
He showed off his new physique in a campaign for Calvin Klein underwear, in which he gradually sheds his clothes and trains in just a pair of jockey shorts.
To get into fighting shape, he told GQ he ran, jumped rope and practiced gymnastics.

Calisthenics dates back to the ancient Greek era and comes from the word 'kalos', meaning beauty, and 'stenos', meaning strength.
It is a type of resistance training that uses your body weight and gravity to strengthen your muscles, increase endurance and improve mobility.
It is similar to pilates and involves simple movements such as pull-ups, burpees, push-ups, lunges, squats and crunches.
“Calisthenics is a form of fitness that uses gravity and body weight to challenge your fitness,” said Kenneth Gallarzo, founder of Systematic Calisthenics. Men's health.
The exercise was originally intended to promote beauty in strength among Greek schoolchildren, who began training at an early age, but is now most commonly used by gymnasts.
Some practitioners even consider gymnastics a more advanced form of training.
Because it offers a wide range of movements, calisthenics can fit into both beginner and more advanced workout routines.

Most calisthenics moves don't require equipment or a fancy gym membership. “All you need is your body and some open space to get a great workout,” Tayo Awoderu, a gymnastics trainer for Steel Warriors, told Men's Health.
The exercises also target a wide variety of muscle groups, including arms, legs and glutes. Push-ups, squats and planks are examples of beginner-friendly gymnastics moves.
There is some evidence that gymnastics can make you stronger. a small study of 28 men, for example, found that calisthenics can improve strength within eight weeks.
After that period, the participants were able to do more push-ups and pull-ups than before, even though their gym routines did not specifically include these exercises.
Additionally, a 2022 study published in the journal Frontiers in Psychology found that fast-paced calisthenics—think burpees or mountain climbers—improved cardiovascular health and increased endurance.
The participants increased their oxygen consumption, which improves heart function.
