Watch Ruth Bader Ginsburg Show Off Her Jaw-Dropping Gym Skills to Stephen Colbert

Supreme Court Justice Ruth Bader Ginsburg, 85, is known for more than her remarkable tenure on the bench as a progressive icon—she's also a well-known fitness advocate.

CBS Late Show host Stephen Colbert joined Ginsburg in the gym for a workout with her personal trainer, along with a conversation about her popular nickname, the "Notorious R.B.G."

“We’re both born and bred in Brooklyn, New York,” Ginsburg said about her overlap with rapper Notorious B.I.G.

After the discussion, Colbert joined Ginsburg for her "super-hard" fitness routine, which includes opera music and some impressive planking.

Ginsburg deftly worked her way through a series of compound strength and core-training exercises that would put most people half her age to shame.
