Move over, Schwarzenegger: New book uses Ruth Bader Ginsburg as a workout inspiration

If you want to get in shape, you’re going to have to feel the Ginsburn.

That’s according to a Washington, D.C., personal trainer who has written a workout book based on the exercise routine of one of his most famous clients: 84-year-old Supreme Court Justice Ruth Bader Ginsburg.

Trainer Bryant Johnson’s book, “The RBG Workout: How She Stays Strong… and You Can Too!� is scheduled for release Oct. 3 from publisher Houghton Mifflin Harcourt, the Associated Press reports.

The book will contain illustrations of Ginsburg, clad in her judge’s robe and “trusty sneakers,� doing the exercises that Johnson has prescribed for her.

Johnson trains Ginsburg twice a week, and her typical routine includes push-ups and “the core-strengthening plank,� according to AP.

A description of the book on the publisher’s website describes it as “kitschy� and promises that it will help readers perform a “supremely good workout.�

“Be warned, this workout will not be a breeze,� the description reads. “From planks to squats to (full) push-ups, this workout will have you fit in no time!�

Johnson has trained Ginsburg, a cancer survivor more than 30 years his senior, for almost 20 years, Yahoo reports.

At one point, the justice left a dinner with then-President Obama early in order to make it to one of her training sessions.

“I said, ‘You left the president for me?’ � Johnson remembers telling Ginsburg. “’Oh man, extra push-ups for you.’�

A Washington Post profile of Johnson, who also trains Justices Elena Kagan and Stephen Breyer, describes Ginsburg’s motivation for first seeking the help of a personal trainer.

“When I started, I looked like a survivor of Auschwitz,� Ginsburg said. “Now I’m up to 20 push-ups.�

Readers who aspire to Ginsburg-level swoleness should be careful: The justice’s workouts are intense, according to Politico writer Ben Schreckinger.

In an article titled “I Did Ruth Bader Ginsburg’s Workout. It Nearly Broke Me,� the journalist wrote, “Ginsburg’s personal trainer, it turns out, is no joke. ... As for Ginsburg’s continued vitality, after going through one of her workouts I can confirm she could not be in better hands. Sore, disoriented and cranky, I didn’t feel a day over 65.�
