I was schooling a horse recently who has very correct and established paces, but isn’t the biggest mover so often has average marks in a dressage test as he lacks the “wow” factor. So I had a play at building some expression into his work.
Once I’d warmed him up long and low, stretching over his back, and had done some lateral work, I opened him up into some medium trot. He lengthened nicely from behind, but he could have given more.
I was riding in a large arena, and you need to have one which is more that 20m wide in order to ride this exercise.
In trot, establish shoulder in at the beginning of the long side. Halfway along, ride out of the shoulder in onto a 45 degree turn, so you effectively cut the corner off, and ask some medium trot. When you reach the short side, approximately halfway along, stay on the same rein in working trot.
The shoulder in collects the horse, gets their inside hind leg underneath them and taking their weight. Which means it’s in a better position to push forwards to medium trot. The turn onto the diagonal line ensures they don’t fall out of the outside shoulder as you ride out of shoulder in and ask for medium trot. Staying on the same rein after the medium trot makes the exercise simpler as they don’t need to change bend, so keep their balance easier and maintain the impulsion into working trot.
The result is a more extravagant and powerful medium trot and an expressive working trot, which is still rhythmical and balanced, yet would earn more marks in a dressage test.
It’s a fun exercise, so try putting it together next time you ride and see if you can feel the improvement in their general way of going as a result.
