Simon Cowell has been voted the 'most punchable celebrity', according to a recent poll conducted by Gymbox.
Gymbox has launched the world's first 'human punchbag' with real people inside to provoke the fitness fans to throw jabs and hooks at someone inside the custom designed bag.
Andy Monk, a look-a-like of the famous media mogul, from Harrow, has become the world's first professional human punchbag by taking on the role.
The concept initiated by the gym in Holborn aims to help fitness fans burn more calories by egging them on with a series of taunts and insults.
The science behind the idea, dubbed 'Goad-tivation', is inspired by the concept of vengeance, one of the 16 identified motivational desires that drives that human psyche.
The other top 10 punchable celebrities include Piers Morgan, Katie Price, David Cameron, Cher Lloyd, Cher Cole, Kerry Katona, Jedward, Justin Bieber and Alex Reid
The gym hopes to recruit more fearless members of the public via Facebook to be its human punchbags.
"Our members expect us to bring them the latest in extreme workouts but they also have to work from an exercise point-of-view," the Daily Mail quoted Richard Hilton, of Gymbox saying.
"It's not every day you get the opportunity to punch someone without ending up in hot water so we think this will be a big hit with members."
"It's no surprise Simon Cowell was ranked most punchable celebrity after his unceremonious dumping of national sweetheart Cheryl Cole from American X Factor earlier this year," he added.
