Here is a good list for you:
-back up (shaking the rope and asking him to back, once he takes a step back, release the pressure, keep doing this until you just have to wiggle it very gently)
-yielding the hind quarters (moving his hind quarters by using your body language or lunge whip to ask him to move around)
-moving forehand (opposite of quarters)
-leg yield across wall (sending him out perpendicular to the wall, you start by following and asking to yield over, once you are more experienced you stay in place and ask them to yield away without you following their every step, and let the rope out)
-any sort of sketchy looking obstacle is great for confidence, letting them be rewarded for just engaging with it, then rest, then come back and use it as their rest spot until they feel like they are safe to be curious, until they desire to do it themselves without assistance
-spiraling in and out on a circle lungeing
-yielding forehand to you while walking in a small circle
-you can teach liberty follow as well, or target train with a clicker or just your mouth
