'Guardians of the Galaxy Vol. 3' star Will Poulter says his training regimen is 'so rigid' that he wouldn't recommend it to anyone

• Will Poulter will star as the Marvel character Adam Warlock in "Guardians of the Galaxy Vol. 3."
• Poulter told The Independent that he's used "different diets over the last few months."

"Guardians of the Galaxy Vol. 3" star Will Poulter said that his training routine for the upcoming Marvel movie is so intense that he wouldn't recommend it to anyone.

"It's been a lot of gym work and a very, very specific diet," Poulter told The Independent.

The 29-year-old actor will make his Marvel Cinematic Universe (MCU) debut in James Gunn's third "Guardians" movie, currently set for release on May 5, 2023.

Poulter will be portraying a popular character from the comics known as Adam Warlock. In the source material, the character is genetically created to be a perfect being.

He has blonde hair, golden skin, and glowing eyes, and his superpowers include telepathy, superhuman agility, superhuman stamina, and the ability to manipulate energy.

The introduction of the character was first teased in an end-credits scene in 2017's "Guardians of the Galaxy Vol. 2."

Since his casting, Poulter has remained generally tight-lipped about his role in the new "Guardians" movie.

In his interview with The Independent, he spoke about the unpleasantness involved in getting jacked for the Marvel role.

Poulter said that his diet has involved consuming "quantities of food you wouldn't necessarily want to ingest" and not eating "enough food" at other times.

"I've gone through a series of different diets over the last few months," he said, explaining that now he's in a stage in which he's maintaining his weight.

"I've gone through periods of looking at food and feeling like I can't face it, and then you blink and the next minute you're ready to eat furniture because you're so hungry," he said.

Poulter said that his social life has also been impacted by his role, and he's "in a routine that is so rigid that being able to go out for dinner with friends is not something I've been able to do."

The "Dopesick" star said that prioritizing mental and physical health is the main purpose and "the aesthetic goals have to be secondary."

"Otherwise you end up promoting something that is unhealthy and unrealistic if you don't have the financial backing of a studio paying for your meals and training," he said.

"I'm in a very privileged position in that respect, and I wouldn't recommend anyone do what I did to get ready for that job," Poulter added.
