Anyone have experience with training up on barrels? anything helps

Start slow. Start with a single barrel and teach your hrose to turn that at the walk, trot, and lope. Be sure have consistent pockets (space between your horse and the barrel). Your horse shiuld also keep his space from the barrel consistent through the turn to keep his hindquarters engaged. If you come in wide and then cut close on the backside some horses will loose engagement in their hindquarters and not be able to push off to the next barrel. When you move up to the while pattern start slow again until horse is comfortable with it. Don't mive on until your horse is 100% comfortable with what your doing.
