"He’s too big to fit in frame," one remarked in the comments section.
"That arm is bigger than my future," mused another.
When it comes to his intense diet and exercise regime, Chris doesn't do things by halves.
During filming for his Marvel movies, the actor spilled on his protein-rich diet and how he'd eat six times a day.
“With the months leading up to the shoot and during filming, I’m basically overfeeding myself on protein and endless amounts of chicken breast, eggs, steak, fish, vegetables, tuna, avocado, cottage cheese, and brown rice,” he said.
“That said, we’ve tried to cut down a bit on animal protein and introduce more legumes and certain grains, as a result of being more mindful about the environment. But to be honest, it’s still mostly animal proteins.”
As for his workouts, Chris revealed: “It’s very easy to go for the showy muscle but for Thor, I don’t want cosmetic muscle."
“You can really tell when someone has functionality – they move differently, and for me, I found it so much better with injuries and general well-being when I upped my functional and core workouts.”
He added: “I now have a far greater range of motion and stronger core. I do a lot more pull-ups and things like that, more high-intensity stuff and extra bodyweight moves.”
It seems good looks certainly run in the family. When Chris shared a series of stunning photos of his mum Leonie celebrating her 60th birthday in November, fans were in awe of her age-defying looks.
'Your mum is 60?!! 😲 wow she looks great! 🙌🏽🙌🏽" one remarked.
"Are u kidding me??... She is 60! No way... She seems to be younger sis..... Omg," another stated.
"Wait what?! She 60?? She look so damn young!!" a third exclaimed.
