Anthony Joshua and Francis Ngannou have both put their thunderous power to the test for fun in recent years.
When a boxer appears on mainstream TV to measure their strength, they are usually not allowed to leave until they have used the famous ‘punch machine challenge’, especially when they’re a heavyweight champion.
AJ did not disappoint during an appearance on the Graham Norton show in 2017.
As soon as he saw the machine, he took his suit jacket off and strolled over to have a turn.
He graciously let fellow guests – actors Rachel Weisz, Martin Freeman and Greg Davies – go first.

They scored 182, 594 and 632 respectively before Joshua turned up and smashed it with his right hand.
He scored 848 – breaking the existing record of 787.
Ngannou took his turn on Gym Shark’s punch machine in London while carrying out his pre-fight media duties for the AJ clash.
This was on a separate machine and so their results are not directly comparable.
However, Ngannou barely threw his weight behind the shot and yet when he connected he effortlessly hit a maximum score of 999.
Ngannou uploaded a video to social media of his earth-shattering punch with the caption: “Who can beat my score?”
“Francis Ngannou has the world record for the most powerful punch, his punch is the equivalent to 96 horsepower which is equal to getting hit by a Ford Escort going as fast as it can,” UFC president Dana White said at the time.
“And it’s more powerful than a 12-pound sledgehammer swung full force from overhead. Holy sh*t!”
However, his record has since been broken by UFC middleweight Joe Pyfer, who landed a thudding shot that registered at 170,218 units – 31.7 per cent harder than Ngannou’s.
Meanwhile, the record on the punch machine at talkSPORT Towers was recently broken by an up-and-coming cruiserweight star.
