Who needs weights when you've got an NBA Hall of Famer sitting around!?!
Shaquille O'Neal proved he's still the "Big Aristotle" at 50 years old ... 'cause the legend just curled Reggie Miller -- with ease!!
A video of The Diesel's recent swole sesh was posted to the 'NBA on TNT's Twitter this week ... and for someone who's been retired from the NBA since 2010, Shaq looks to be in great shape.
In the clip, you see the legendary Pacers guard jump into Shaq's arms -- O'Neal didn't budge a bit -- and the former Lakers big man completes 4 full curls!
