I know this is a REALLY late response, but I really wanted to say something. First of all, I love how quiet you are in the seat (looks very pretty and soft). It looks like you have a good foundation and lots of experience. However, it seems we have the same problem... pulling on the reins. I ride a young gelding (4 years) and he can be super forward. As a response, I clench and constantly pull. I imagine you do the same thing. I’m not trying to say you’re scared, you’re just trying to prepare for what your horse it going to do next. My solution is RELAX. If you loosen your reins and move your hands out of your lap, your horse won’t stiffen up because of that constant pressure. It will also help your horse put their head down and start to work over their back. If you expect something to happen, IT WILL HAPPEN because you’re thinking about it and not focusing on what’s ahead. This will make riding a better experience for both you and the horse. This tip has helped me and my pony so much. Again, I know this is late and I’m sorry.
