Chris Hemsworth leaves fans in shock after he shows off bulge in workout video

Marvel star Chris Hemsworth has left his fans speechless after sharing an unintentionally NSFW workout routine.

In honour of the actor's 41st birthday this weekend (11 August) we’ve decided to revisit the time he left fans with their jaws on the ground after posting a workout video which left very little to the imagination.

You’re all welcome, by the way.

Taking to Instagram, the actor decided to get his followers motivated by giving them a glimpse into his workout routine, captioning the video: "Good little session. Finishing it strong with some core.”

However Hemsworth's routine of pull-ups, crunches, and boxing drills was the last thing on anyone’s mind as they were all way too busy staring at the sizeable bulge in his trousers.

Check out the, ahem, eye-opening clip below:

"Good little session. Finishing it strong with some core," he captioned the video.

Now Hemsworth is best known for playing Thor aka the God of Thunder in the MCU. But if this clip is anything to go by, it seems like he's got a Mjölnir war-hammer of his own.

For the most part it wasn't too obvious, but when it came to the Thor: Love and Thunder actor's last exercise, fans just couldn't look away.

"Thank you both for the performance," commented one awe-struck fan.

"So they let you keep the hammer?" joked a second.

A third cracked: "The last exercise, wasn't it supposed to be one leg at a time?"

And a fourth added: "That um… um last exercise... respectfully DAYUM."

And let's just say Instagram's feature that allows users to leave GIFs in the comments was being put to use, too.

Chris was also cheered on by his health and fitness company Centr, who left a much more civil message in the comments.

"Our fearless founder leading by example," they wrote.

Centr, according to its website, provides users with personalised tools and workouts so you can train like Chris.

"What started as Chris Hemsworth’s personal wellness journey has evolved to inspire millions to unlock total well-being,” they say in their mission statement.

"Always deeply passionate about health, it wasn’t until he needed to train like a superhero that Chris connected with world-class wellness experts to achieve his goals."

But it isn't just exercise that helped Chris get that Thor physique. Food has been a key part of the actor's training journey.

According to his personal chef Dan Churchill, Chris would consume 4,500 calories per day while training to play Thor.

Those 4,500 calories are broken down into 10 meals per day, and the more I think about it, it's a wonder that Chris has time to do anything besides eat and train all day.

As well as helping out Chris with his superhero diet, Churchill creates recipes for Centr users to help them get the right nutrition to match their training - though the rest of us probably don't need the full 4,500 calories...
