People/clinicians often stretch the lats to improve overhead mobility. If something feels tight, and you stretch against it, the muscle has to actually fatigue in order to relax against the perception of stretch. It's much more comfortable and faster to slack a muscle that is limiting motion. In this case, I slack the latissimus dorsi on a PT with limited overhead mobility and trunk rotation. Both improved afterward so that now she can groove and load the new motion threat free. Are you a patien
