Fifty-five per cent of Americans polled said they could beat the president in a fight.
Just 19 per cent backed the president over themselves. The rest were undecided.
But people backing themselves over the president were far more likely to be Democrats than Republicans.
Just four per cent of Democratic men thought they would lose a physical fight to Trump, with 82 per cent thinking they would triumph.
Democratic women were almost as bullish, backing themselves over Trump 71-7.
They were substantially more confident than Republican men, who only thought they themselves would prevail by a 46-25 margin.
Only Republican women thought they would lose in a fight to the president, by a 19-55 margin.
Perhaps most embarrassingly for the president, people were asked who would win in a fight between him and an eight-year-old boy.
Trump was backed by 45 per cent of those polled, with 31 per cent tipping the eight-year-old.
Just 10 per cent of those polled thought Trump could beat the average American in a fight. Sixty-six per cent said the average American would prevail.
The poll was inspired by an exchange between Trump and a young child in the Oval Office this week.
“You think you could take me in a fight?” the president asked the boy.
The poll comes as Trump prepares to host a UFC event on the White House lawn.
The event is being held to mark the 250th anniversary of the United States.
“This will be the greatest show on Earth,” Trump said.
“Some people can take a punch and some people can’t. And in life, it’s always good to be able to do that.”
While YouGov is a well-regarded pollster when it comes to forecasting election results, it has been known to ask kooky questions in their surveys.
A 2023 poll asked Americans how confident they would be in landing a passenger plane in an emergency situation.
And a 2021 poll asked people what animals would win in head-to-head fights.
Elephants were deemed the most likely winners while geese were the least backed option.
