Why Can't I Do This Exercise? (Reformer and multi-apparatus) (3 NPCP CECS)

From Shari's workshop description: "You know that exercise you can’t seem to do even though you’ve been doing Pilates for a long time? What about the one your client’s can’t seem to accomplish and you can’t figure out why they can’t get it? Every exercise is accomplishable by everyone. It’s a matter of letting the exercise expose the weaknesses and imbalances and then strengthen and balance…right? Yes…but there’s more. We have to actually know what the issue is. When your legs fly up in The Roll Up, it must mean you need more abdominal strength, right? Actually, no. When your hip flexors hurt in your Teaser it must mean you need to turn off your hip flexors, right? Again, no. What myths are we working with that are still hindering our exercises…which hinders our ability to develop strength and balance of soft tissue tension and ultimately help us achieve our physical and professional goals?"
