Hi Anna,If clenching the glutes helps you stabilize and keep the movement in the upper body I think that is ok. For me, as I push the shoulder forward, the ribcage will rotate a bit with it so in that way your ribcage or chest as you say is also shimmying. I am not actually fully isolating the shoulder movement. I hope that helps. Keep up the great practice.
