The president is furious over media speculation following his sudden trip to a government hospital outside Washington last Saturday and the startling tweet was his latest attempt to put talk of ill health to rest.

In the picture, Trump's head is superimposed on the hulking body of a boxer — an image taken from the publicity poster for the Sylvester Stallone movie "Rocky III."

The montage, in which a distinctly airbrushed version of the 73-year-old president's face is used, comes without comment.

But the Internet went berserk over the photo and came up with comments.

Netizens have shared their own version of photo-shopped images of Trump.

Not that the Republican real estate tycoon is shy on the subject. He rarely misses a chance to talk up his own physical prowess and often makes unscripted comments -- flattering or derogatory -- about the physique of other men, often to their face during official events.

On Tuesday, while giving a reelection campaign speech in Florida, Trump fumed at length in a bizarre rant about his recent hospital visit.

And another one...

He claimed, wrongly, that major media outlets were reporting he'd had a "massive" heart attack when he was taken, without prior notice, to the Walter Reed military hospital.

In fact, most media questioned the unusual circumstances of the visit, which would usually have been flagged in advance. The White House said afterward that Trump had simply decided to do part of his annual physical exam early, in order to save time later.

Some even included Melania in to the Twitter war.

According to his last medical exam, in February, Trump is technically obese but in good health. He rarely exercises, other than playing golf -- as he did at his Mar-a-Lago resort in Florida on Wednesday.

At the campaign rally, Trump told supporters that false media reports of a heart attack sparked worry among staff back in the White House.

But in the hospital, he claimed, doctors had only had one overriding concern -- to witness his spectacular physique.

The Obama comparison has to come…

"The first thing they do is say, 'Take off your shirt, sir, and show us that gorgeous chest. We've never seen a chest quite like it,'" he said.

Aside from praising his own chest, Trump launched into a description of the muscles of Republican Florida Governor Ron DeSantis -- a man Trump explained he previously thought had been fat.

The reality...

"One day I am with him and I pat him on the shoulder and I go, whoa! That's strong," Trump recalled to the crowd of thousands.

"That's a lot of muscle there. My hand didn't sink in like it does with a lot of people. And then I see him without a shirt one day, and this guy is strong. He's not fat. That's all power. That's all muscle. I want to tell you that."
