Dwayne "The Rock" Johnson has been a celebrity and an actor for so long, it's hard to remember his roots as an actual athlete. A recent photo to Instagram serves as a great reminder.

The Rock played football at the University of Miami and was a superstar in the WWE. He's trained with Seal Team 6 and thrilled us at Wrestlemania.

On Tuesday he shared a selfie of himself working out at the gym, and good lord are his legs gigantic. The Rock could kill any of us even if he was born with no arms.

Rock also provided clues about his next movie role in the pic's caption.

 2 weeks away from shooting CENTRAL INTELLIGENCE - big action comedy with Kevin Hart and director Rawson Thurber (We Are The Millers). My character was relentlessly bullied in high school just because he was "different" than the rest of the students and never ran with the "cool crowd". He was chubby, eccentric and enjoyed singing chick songs. He quit high school, changed his name and years later became the CIA's most dangerous contract killer... and also the weirdest. I'm pushing all chips in - 100% committed to this character & story to bring y'all something good. He's dangerous, loyal, lovable, kinda f*cked up in the head and wears a beautiful fanny pack. #HelloMyNameIsBob #AndNoOneBulliesMeAnymore #CentralIntelligence #BOSTON
