This is a funny topic that seems to be wildly polarizing. I've ridden with a lot of different trainers. Some of them are like "OMG MOVE THE BIT IN THE HORSE'S MOUTH SO IT'S NOT DEAD" and others are like "OMFG STOP MOVING THE BIT BC OBVIOUSLY YOU ARE A FAILURE"
Or something. Those possibly aren't direct quotes, but I tried to capture the essence.
Now I assume that we're all of the school of thought that we do in the moment what works at the time for the horse that we're riding, but what does that look like for you? Hands still? Fingers moving? Hands moving? Eff it and loopy reins?
