Talk about the ultimate flex ... Giancarlo Stanton showed off ALL of his muscles in front of smokin' hot model Adriana Lima -- BY BENCH PRESSING HER!!!
The video of the Yankees superstar in the gym is insane ... he laid down on his back, grabbed Lima by the legs and the armpit -- and benched her AT LEAST 4 times!!!
It's unclear why a normal barbell and plates weren't enough for the outfielder ... but Lima sure seemed to dig it -- the supermodel was smiling the whole time!!
Of course, the feat ain't exactly tough for Stanton ... he's known as the strongest guy in the league -- so benchin' a former Victoria's Secret model was clearly NBD.
But, just to prove the guy could still lift some serious weights ... he showed off his skills with a hammer and a tire -- and yeah, dude's got the muscles!!
Seems clear all the injuries that bothered Stanton during the 2019 season are now behind him ... which means, heads up, Red Sox.
