Supreme Court Justice Ruth Bader Ginsburg wasted no time bouncing back from a November fall that broke three of her ribs — working out the very next day.

The famously fit jurist, 85, and her former US Army personal trainer Bryant Johnson “went back immediately after the fall,” the Notorious RBG said at a sold-out Saturday event at the Museum of the City of New York, according to CNN. “[But] we could do legs only.”

“But yesterday, we did the whole routine,” said Ginsburg to thunderous applause, adding that her ribs are “almost repaired” following the scary Nov. 8 fall in her Washington, DC, office.

That hourlong routine, The Post reported last year, includes a five-minute treadmill jog, followed by a gauntlet including stretches, presses, curls, rows, squats, push-ups, planks and kicks.

“The whole routine that most 35-year-olds can’t do,” marveled the interviewer, NPR’s Nina Totenberg.
