In that video yes, she was asking me to turn him left instead of right like we had been doing because we weren't sure if it was me that was causing him to dip out to the right or him.
Other than fixing my wonky arms, is there anything else you could recommend me doing to let me hips become mobile?
This may sound a little coarse but if you thought sex with your hips I bet you would have no trouble at all. To ride well you need to feel that motion so instead of riding on top of your hips try to push them forward with the motion of the horse ( thus being "sexy"). Having your arms too straight forces the shoulders forward and that results in you placing all your weight over your hips ( and locking).
I tell my students to put their elbows so they brush their side and the minute they can't feel them there take a look for they will have traveled too far forward ( unless you intentionally move them forward to release the reins).
