This is potentially a silly question, but here goes: When it comes to corrective exercises (exercises to improve posture, pre-hab or re-hab injury and/or address strength imbalances) is hypertrophy necessary? If so, does this mean the effectiveness of such methods will be decreased if one is shedding bodyweight? Intuitively it would seem to be context dependent. You can improve the way that your glutes activate without necessarily needing to make them bigger. I am speaking specifically, for my case, of needing to improve my VMO strength/size to assist in patellar tracking. Upper back work (e.g. facepulls, rotations) for shoulder health seems like something that would benefit from hypertrophy, also.
