Hey guys This was both myself and Claire’s first go at the box strict hinge. She suffers from low back pain which she attributes to sitting all day! After her latest episode I offered to help her solve it. This is the first time she has felt her glutes working hard which is something she has never be able to do….so thanks for this one Ash. The video doesn’t do it much justice but she had some serious shakes going on. We worked on it for a few sets and when we finished she could feel a numbness across her low back which isn’t unusual for her. Any ideas as to why this might be? Any feedback/help at all is greatly appreciated.
