You can help your horse stay in good balance by sitting evenly on your seatbones.
Here’s a cool image to help you make sure you’re part of the solution instead of part of the problem.
Imagine you're sitting on top of a basketball.
If you lean forward, the basketball shoots out the back.
If you lean back, the basketball shoots out in front of you.
If you lean to the right, the basketball pops out to the left.
If you lean to the left, the basketball pops out to the right.
If you're sitting straight and evenly on your seatbones, you can keep the basketball directly on top of your horse's back.
