Here is a video where I tell about the importance of being able to get the horse mentally relaxed.
It is important that during our training lessons, we can alternate between getting the horse "a little up on the marks" and then getting it down in a relaxed state again.
But many forget the relaxation phase !! This causes the horse to learn more slowly. It causes the horse to keep holding some tension in its body. The horse will lose muscles and it will lose its trust in us.
So remember the breaks during training !!
