Bend to the inside and bring your outside leg behind the girth and ask
Practice lead changes in a figure 8. You'll want to make sure that your weight is on your outside hip, then at the center of the figure 8, shift your weight to your other foot (sit back!) and curve your horse the other direction. It's kind of hard to explain, but one you do it, it just clicks! 🐴😊
Change your bend and use the outside leg (of the direction you want to go in, for example, if you're doing a change to the left, use right leg and left bend). But first ask your trainer if you're horse knows how to do them, I'm not sure how you'd teach him/her if he doesn't. :) good luck!!
