Chris Hemsworth is generally known as Hollywood's #2 favorite Chris.

But there's one thing he's Hollywood's #1 Chris in — arms.

His arms are huge.
Like, the size of multiple babies huge.

He shared a picture of his ginormous arms on Instagram, and I really just had no idea they were *that* big:
Whew.

That's a very big arm!

For reference, you can fit ABOUT three of Chris Hemsworth's heads into his arm.

Many babies!

This tweet by Justin Bieber on New Year's Day in 2012 sums up my feelings best:
i love arm
