This picture is of me and my first jumper gelding. I've been jumping for years, and my horse came from huge jumping bloodlines and training. Unfortunately, he'd never jumped the open water before. So I got a bath out of the deal! So even when you think you know what you're doing, sometimes they surprise us and that's when injuries can happen. I, like the rest of the folks above, believe you need to start at a training barn. Even if you take a few lessons on the lesson ponies. It's the best way to get the body mechanics down on a horse that knows the job and will pack your butt around.
