Danica Patrick may have retired from NASCAR racing, but still trains hard to stay fit. She posted a video on Instagram recently working out with sister Brooke and wrote: "That was so fun to end the 12 days of Christmas workout with 95lb thrusters!!!! @brooke_selman is so tough! Obviously we are quite compatible, looked more like a simultaneous workout than a race. @crossfit @roguefitness @prettyintensebydanica [this workout is not in my workout program!... which starts January 7th so go get the book!]."
