Hinge vs. Squat - ER for Movement - IR for Force - BillHartmanPT.com Q&A for The 16%

https://billhartmanpt.com/ https://ifastuniversity.com/ Today’s Q&A is a discussion that started in talking about “hinging” activities and evolved into how the hip and pelvis may be constrained or allow relative movement to occur or not. We move in spaces and not in straight planes. IR is superimposed ER. Where the space for movement exists is determined by shape and the ability to change shape. #hiphinge #squatvshinge #BillHartmanPT
