Whatever your politics, you can’t deny that Supreme Court Justice Ruth Bader Ginsburg is one strong woman. Not only is the 85-year-old one of just three women presiding over the Supreme Court, she’s also a pancreatic and colon cancer survivor—and, oh, she can do 20 pushups.

Yep, in addition to regularly making monumental contributions to women’s rights and law in the U.S., RBG works out for an hour twice a week with her trainer Bryant Johnson, C.P.T.

In the past two decades of working out with Johnson, the Justice has perfected bodyweight strength moves like one-legged planks and assisted pistol squats. The legend of her fitness prowess has spread so far and wide that Johnson even wrote a book—aptly named The RBG Workout—about it.

In the foreword of the book, Ginsburg writes that she hopes her workout will “help others to experience, as I have, renewed energy to carry on with their work and days.” (And trust me, I know firsthand that this workout is no joke. I tried it for myself live on Facebook and sweat buckets.)

So, want to be like RBG? Johnson, who’s also a member of The Vitamin Shoppe’s Wellness Council, shared a sample gym session with us so you can put your fitness to the test. After warming up with a few minutes of cardio and a quick full-body stretch, you’ll be ready to jump right into RBG’s full-body routine.

It’s all about having strength, stability, and mobility for life—and it’ll kick your butt! Think you’re ready for it?
