Antonio Brown and Josh Norman are droppin' sweat in South Beach with Miami's version of Gunnery Sergeant Hartman ... smashing beach drills while their trainer unleashes hell -- and it's awesome!!
Seems like AB and Josh are goin' 100 -- and you would be too with this dude barking orders at ya ... not to mention smoking elite athletes on the sand.
At one point, he hits Antonio with a speech that's equal parts motivating and demoralizing ... before making the Steelers star pray for divine intervention at the Super Bowl.
