The two former NBA stars and current TNT employees hit the gym together in Cleveland ... where Shaq decided to show off a little bit.
Check out the clip ... Shaq says he's going to lift C-Webb "instead of take shots" -- which could be a reference to the drama involving Webber and his old Fab Five teammates.
FYI -- Webber has been going back and forth with Jalen Rose stemming from a rift over a documentary about their legendary college hoops days at Michigan. Maybe Shaq was suggesting they worked it out already.
And if not ... it's still a pretty incredible feat of strength -- Chris reportedly weighs about 245 pounds.
