You can say what you like about the role of genetics, personal trainers and top quality equipment, but the fact of the matter it is that nobody on this planet has got themselves in tip top physical condition without putting in some hard graft.
Dwayne 'The Rock' Johnson is revered among gym goers for his incredible henchness. At 47 years old, his 21-inch biceps are as beastly and impressive as ever, and in a video shared on his Instagram, it's plain to see it takes a hell of a lot of elbow/arm grease to maintain those monsters.
In the video, Johnson can be seen executing his '21s finisher', which is quite different to his in-ring finisher, The People's Elbow... there's a lot less prancing about, basically.
The routine is comprised of seven reps from the top, going halfway down, followed by seven reps from the bottom, going halfway up, and then closing with seven full reps. After a full workout, you can only imagine how painful/impossible those last seven reps must be.
The Rock shared the video - which has been viewed more than four-and-a-half million times - with the caption: "21 inch Gun salute. Hellish bicep :muscle: finisher I love called 21's.
"7 reps from the top going only half way down. 7 reps from the bottom going only halfway up. 7 full reps.
"And pushing past your pain threshold to squeeze out a few more extra reps is where success and magic happens."

We shouldn't really be too stunned by this latest vid, though. Anybody who has come across his Instagram before will be well aware that 'The Most Electrifying Man In Sports Entertainment' often shares pics and videos exhibiting his enviable bod.
Last October, he shared a picture of himself looking particularly superhuman after '18 weeks of disciplined diet and intense training' in preparation for shooting Hobbs and Shaw.
In the post he modestly said: "Always room for improvements, but not too bad for a scarred up surgically repaired Brahma Bull whose injuries always tell the story."
Seriously, where the hell is the room for improvement here? Credit: Instagram/The Rock
It's tough to know how to take that, really. On the one hand, it should really inspire us all that a man in such impeccable condition strives to better himself, but then on the other hand, you can't help but feel a bit like telling him to fuck off, cos if he thinks that temple needs improving, what the hell is he gonna make of our flabby figures?
Obviously, no matter how you feel, you ain't gonna tell The Rock to fuck off - know your place, and shut your mouth.
