James, good effort getting started straight away, mate 💪 Bending your knees to keep your feet off the ground is absolutely fine. For scapular pull-ups, keep your elbows straight and pull your shoulders down away from your ears. Your body only rises a few centimetres, then lower slowly, without swinging. With that setup, though, I can’t confirm from the photo that the red bar is suitable for hanging your bodyweight from. If the yellow bar obstructs you or forces you into an awkward position, find a clearer spot. You also may need a solid bar, this looks like foam. The video bellow shows the movement you’re aiming for. If you can post a short clip of yourself doing it, we can give you much more useful feedback on your technique. 🛡️ https://youtu.be/QEOHnH7Wpsg?is=Siy2ita3ECJDgKn-
