Eddie Hall embarrasses Anthony Joshua and Deontay Wilder by breaking a punch machine in warning to Hafthor Björnsson.
Hall, 33, will take on his strong 32-year-old rival in a super-heavyweight boxing grudge match next year.
And Britain demonstrated its punching prowess by smashing a machine that professional fighters AJ and Wilder failed to conquer.
Hall tried his luck on the Bio-Synergy bag at the Arnold Sports Festival over the weekend, just months after the infamous ‘Power Cube’ attempt.
The 2017 World’s Strongest Person winner took a big hit on the machine.
But as soon as the power gauge number started climbing, it suddenly stopped.
Bio-Synergy tweeted: “Think Eddie Hall broke our machine, Facebook, Instagram & WhatsApp with that punch.”
Boxing fans will be hoping to see some similar punches between Hall and Björnsson when they finally meet in the ring.

And Hall is confident he’ll be better than the Icelandic legend, who demolished arm wrestler Devon Larrat last month with a first-round KO.
Hall told Luke Fullbrook: “I’m very confident. You know how seriously I take things. I’ve shown absolutely zero material in terms of how good or bad I am.
“I’ll just let my fist do the talking. He can say or do whatever he wants, but at the end of the day I’m going to outsmart him.

“All that matters to me is that he is getting knocked out.
“I haven’t even started the mental game with Thor and he’s already calling me a bully. Better catch him himself, because it’s going to get a lot worse.
“Those press conferences are going to be very stressful for them.”
