Let me say that doing warm up exercise is never going to do harm. There is no reason to believe that it is a bad thing. But for most of us, it probably does not offer many advantages.
It seems a willingness, if lacking when a horse is first handled and trained, can be taught, encouraged, and nurtured by the human. Is work ethic similar…
I have been thinking, if I were Santa, what is the one training skill I would want to give every horse person for Christmas? Many things come to mind - feel, patience, kindness, a questioning mind, etc.
