After your warm up, move into glute bridges. I do one set of 10 (I’m all about the minimum effective dose). A glute bridge is a great way to mitigate the effects of the large amounts of sitting you’re about to do at work, on the bus, in the car, or on the couch. Being at the top of a glute bridge is essentially the opposite position of sitting in a chair. Your hips aren’t flexed, your chest is open, your shoulders are back. It’s a great way to open up your body.
