Any horse can be taught to stand. You just need a reliable method for teaching him that skill. Once you’ve trained this skill, every other skill you are working on will become much easier to teach (even the ones that don’t involve being still.)
The online class includes over 3 hours of class video plus more than $60 of downloadable materials.
This training can be used with horses of any temperament in any discipline. I've never met a horse, no matter how well behaved or rank that hasn't benefited from this lesson.
