No hips? No problem. She’s a nearly-80-year-old sweetheart and doing some of her physical therapy exercises after her 4th hip replacement (got both replacements replaced).
Prior to the therapy she’d done no real strength or corrective work (hence the replacements); but I gotta give her credit that she’s taking it seriously now. AND, therefore, I’d add that here’s proof positive you can always make progress. I made only minor input with regard to placing her center of gravity over mid-foot and utilizing the hip extensors some. However, what I want people to take away from this is prior to that cue (video here: https://www.instagram.com/p/B5XqoxTjGmn/), she could not stand up without holding onto something. A lot of what we think of as strength is skill. A lot of older people’s bad movement is mostly due to being under or unpracticed.
