Judge Judy works out harder than you — the wellness regimen that keeps her looking and feeling sharp at 81

Judge Judith Sheindlin has found the beauty in being fit for more than just swinging her gavel.

“I have a responsibility to keep the vessel in shape and looking good,” the Daytime Emmy winner told The Post of her twice-daily exercise regimen.

Both in and out of the courtroom, the 81-year-old legal luminary is a powerhouse who refuses to allow age to limit her reach. Working out every day, for a total of 10 hours a week, has become second nature to her.

Rather than relying on a personal trainer, Judge Judy does her own thing, at her own pace and in her home gym space.

She and her husband of four decades, former New York Supreme Court Judge Jerry Sheindlin, 90, get their heart rates pumping for at least 60 to 90 minutes each morning.

She enjoys getting a good sweat in on either the treadmill or through resistance strength training. But for Sheindlin, her exercise regimen is less about vanity and more about mental fitness.
