I'm wanting to work with one, maybe two of the horses at our stables, and teach them how to jump. Only one of the horses knows how, so I might learn (myself) how to jump on her, but then I'd like to teach a few of the others how. It'll make them more desirable for people who want to ride or own them.
How would I go about it? Do I use rails on the ground to begin? What are some exercizes I can do (with me or with the horse) to help?
