picked this up from the library today. it's a little yellow, hardcover book. the size almost reminds me of those Beatrix Potter books i used to read when i was in elementary school!
the pictures are hand drawn by Patrick Welsh, including RBG who is demonstrating each move. when you open up to a page, it has a drawing of RBG doing the move on one of the pages, with explanations/tips on the opposite page. the last page of the book has a photo of Bryant Johnson, her trainer, and when you turn that page, there's a picture of them together in sweats, where RBG has the words "Super Diva" ironed onto the front of her shirt.
the workout looks very doable - easy moves illustrated with weights, bands, stability ball, aerobic bench for step-ups; some moves are done with machines with a non-machine alternative shown. there are several moves done with just body weight (planks, push ups, and floorwork).
her trainer has several justices, attorneys and clerks as clients, plus military personnel and civilians.
