I have a new client who needs to avoid hip flexion exercises because of low cartilage. (She is young and otherwise fit.) I’m trying to compile a list of lower-body exercises. She’s allowed to do body-weight squats. She’s not allowed to do lunges or anything that brings her hip up more than 90 degrees. I’d imagine things like reverse hypers or hamstring curls or bridges are okay. What about romanian deadlifts? Hip thrusts?
