I'm still trying to figure out to ride Gadget up and not lock up his neck in certain movements. Our nemesis is the shoulder-in currently, particularly to the left. So hard for me to remember how to not screw up everything about the shoulder-in. What seems to work: Do not pull back! Position lightly and keep hands up (like puppeteer). Move shoulders first, but do not let him lean on your hands Remember to keep legs wrapped around to keep him stepping Keep seat moving - think of bouncing and actually pushing with the seat a little more. This also keep my hands/elbows a bit looser
