When I want my horse to have a cruisy ride, it is tempting to just wander around and not ask anything of him. But my horse knows when I am pleased with him. If I want my horse to have an easy period, I try to come up with simple challenges for him. This way he can still feel a sense of achievement. The flip side of this is of course not asking the horse too much, or over challenging him. If it felt good to you, chances are it felt good to the horse. A series of simple challenges for a horse will do more to rejuvenate his mind than just wondering around.
