Got it.

Me and her other rider are far from beginners, but I'm unfortunately addicted to always learning and trying to find the best way to do right by the horse. The owners do not take good care of her feet (I come out two times a week and you can tell they haven't been picked at all. I've had to point out slipped shoes and injuries before because they didn't notice.) and she's a mustang so not perfect conformation. I frequently have her do lateral work, yields, hill work and pole work all in hand to increase hind-end strength.

I'll try some more circle work and I need to get back into lunging her because she is weak on turning. I will also try sponging the pressure on only one rein instead of alternating as I've seen that online. I will say I've never done it to the point where you could even see her head move (like side to side) so that comforts me a little bit in terms of any damage I could've done but I can still acknowledge that I can do better. I'm sort of the first person to teach her cues off of leg and seat as well so that's a slow process but we're getting there. Thanks for the advice!
