Ruth Bader Ginsburg turned 86 on Friday — here's the workout she uses to stay on top of her game

• Supreme Court Justice Ruth Bader Ginsburg turned 86 on Friday.
• Many began to speculate when Ginsburg would step down from the bench after Justice Anthony Kennedy announced his retirement last year.
• But Ginsburg is not defined by her 86 years of age. She works out with her personal trainer, Bryant Johnson, twice a week for an hour.
• Her workout is a series of full body strength exercises that target arms, chest, legs, back, shoulders, glutes, and abs.
• I decided to give Ginsburg's workout a try for two weeks — here's what happened.

Supreme Court Justice Ruth Bader Ginsburg turned 86 years old on Friday.

If you are looking for evidence that Ginsburg isn't retiring anytime soon, just try her workout.

After Justice Anthony Kennedy announced his retirement, people began speculating when the liberal bastion might step down from the bench. But Ginsburg works out with her personal trainer, Bryant Johnson, twice a week. She has called him "the most important person in her life."

Johnson and Ginsburg have been doing the one-hour workout that he details in his book, "The RBG Workout: How She Stays Strong and You Can Too" for 18 years, aside from the three years he was deployed in Kuwait.

The workout starts with a five-minute warm-up and light stretching followed by a strength training session that includes push-ups, planks, chest presses, squats, and hip abductor exercises, then another round of stretches to cool down.

Here's what happened when I tried the workout for two weeks.

I am no stranger to working out.

I have completed four half-marathons and go to fitness classes frequently, but I haven’t done much strength training recently because I was training for my races. I was expecting to be sore after the RBG workout.

I was up for the challenge of working out like Ginsburg, especially if it came with an honorary JD from Columbia University, a seat on the Supreme Court, or just great biceps.

But I didn't realize that I would want to recuse myself when I saw that pushups were followed by medicine ball pushups and two different types of planks.

If you work out from home, you'll need dumbbells, resistance bands or tubes, a door anchor, a medicine ball, a Swiss ball, and a stool or ottoman.

I worked out at my local gym, because I didn't think I'd be able to get into the Supreme Court gym where Justice Elena Kagan and Ginsburg work out.
