Horse Training Success

This video is titled 'Really bad jumping from a lazy horse' (warning - loud music), but it looks to me as though the trainer here has got the cavaletti spaced out wrong for the horse. Why? Well he always trips on pole 3. The distances between poles 1 and 2, and then 2 and 3 are different. Not to mention that the horse has no room to land and prepare for the next jump (pole 3). Here's a tip - if your horse ALWAYS mucks up a pole, look closely, it may be that you made a mistake laying them out. And don't do what this trainer does and leave the hit and scattered poles lying about and keep working the horse over them. Tidy them up then get going again.
