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.
It was important to me to get into character in the name of journalism, so I took fashion tips from the book's illustrations of Ginsburg and, of course, her Supreme Court style.
No one at the gym stared at me when I changed into my robe and my faux jabot (that's the name of the ruffle!), but people came by to chat when they saw me toting the book from machine to machine and studying it diligently before starting a set.
The workout starts with a 5-minute cardio warm-up followed by rotational exercises and stretches. I worked out for a little more than an hour.
Then you move into a series of strength exercises targeting your chest, legs, back, triceps, legs, arms, shoulders, glutes, and abs. It's an efficient full-body workout.
You do multiple interval sets and repetitions for each exercise.
When you are choosing a weight, pick one that allows you to do eight reps without much difficulty, but causes you to struggle a bit for the last two to four reps, Johnson wrote.
He adds that you shouldn’t focus too much on the numbers. "It’s not about how much RBG can bench … it's about making sure she feels good enough to stay on the Supreme Court bench," Johnson wrote in the book.
I did the push-ups on my knees and took short breaks when my arms got sore, which is OK because the workout leaves room for building strength.
"Remember, it took Justice Ginsburg years to perfect this routine — even some young ThunderCats can't complete this workout on their first try. As you first attempt this workout, don’t expect to complete it quickly, easily, or even at all," Johnson wrote in the book.
The workouts were tough, and I was consistently sore the next day.
As an equipment novice, I now feel confident using the equipment in the book because of the detailed steps and pictures of the "Super Diva" herself. (Now I just need to find her "Super Diva" shirt.)
The verdict is still out on how fit I'll get from the workout.
Two weeks and four workouts isn't enough to see major changes. But I plan to continue, so I can impress the justices when I get my invitation to work out at The Supreme Court.
