In this entry, I will discuss how you can use this principle to help improve your reining spin.
The most common problem I see beginners have with the reining spin is that they can't get their horse to spin autonomously. They can get a turn around, but they have to micromanage every step to keep the horse on the pivot foot, not walking forward, not backing up, etc. Their real issue is that their horse doesn't want to be in the spin in the first place! Every time the horse is spinning, the rider is pulling the reins and bumping with the leg. Then when they finish the spin, the pressure finally goes off. The issue with this is that the only release the horse can find is at a standstill. This makes the horse want to finish the spin rather than continue to spin. Instead, we can create desire in the horse by moving that release to when the horse is in the spin.
When I ask for a spin, I'll put my leg on, pick up my reins and the second my horse starts spinning, I put my reins down and take my leg off. If my horse stops or walks off, I'll put him directly back into the spin. Again, when he starts to spin, I release. Pretty soon, he starts to recognize that the only release is in the spin. When he locates this release, he will start to spin on his own until I ask him to stop.
Horses should keep doing what they're doing until we ask them to do something different. How does a horse know that he should keep trotting when we ask him to trot? Because he has made the connection that the release is in the trot and he should keep trotting until we ask him to change gait. This same principle applies for the spin. Keep spinning until I ask you to stop spinning. Soon you'll have a horse that wants to spin and stay spinning. Anyone can make a horse perform, but a true horseman can create willingness and desire in the mind of the horse.
