From there it was leg curls and leg presses, chest flies and lat pull-downs, all on machines, while stretching the muscle groups being exercised in between sets." "RBG’s routine has progressed from sit-ups to planks (though she reportedly isn’t a huge fan of the change). Then onto strength workouts for the arms/shoulders followed by leg/hip flexibility moves." Unlike that Scalia slob who looked less healthy than John Belushi, RBG takes care of herself.
