This is a pole layout I did a few weeks ago now with clients, which had numerous exercises within it to benefit a wide range of horses and riders. Lay out a triangle of poles, then place a pole four foot away from each pole. Then build another triangle with outer poles next to it, so that there are three trotting poles in the centre.
The first exercise I used with my riders was in their warm up, getting them to trot and canter between a pair of poles. This really helped identify any crookedness in the horse, and encouraged the riders to minimise their inside rein aids. Initially, I only had them riding through one pair of poles but towards the end of the warm up I got some riders to ride an arc through the two tramlines on one side of the formation, a bit like a shallow loop. This started to get the horses stepping under with the inside hind and using it correctly because they couldn’t drift through their outside shoulder due to the second pair of poles.
Just by using these poles in the warm up I found both horse and rider were more focused and their way of going improved by making them straighter.
The next exercise I utilised was getting my combinations to trot over the tramlines and then over the apex of the triangle. The tramlines were set as trot poles, and both horse and rider had to be accurate to the apex. I had my riders ride across the pole layout from various points, integrating the poles into their flatwork circles and shapes. This means the horses are less likely to anticipate the exercise and the rider can then take the benefit of the polework onto their flatwork and feel the improvement immediately.
If a horse persistently drifts one way or the other over the poles it tells you which hind leg is stronger, which leads me to developing some exercises to improve them. Likewise, it can help to identify any asymmetry in the rider’s seat or aids.
You can also ride from the apex to the trot poles, which is a harder accuracy question because the poles draw the horse away from the point, rather then funnelling them towards the apex.
With my more balanced horses and riders I rolled the tramlines out so they were nine foot apart, which meant they could canter over the poles and apexes.
To add a layer of difficulty to this route, some riders rode curves through the triangles, entering over the trot poles of one triangle, trotting the three trot poles in the centre before either trotting out over the apex, or left or right over another pair of poles.
The final route I had my riders take was along the length of the pole formation; trotting over an apex, over three trot poles and then over the other apex. This was a good test of their straightness, and by removing the middle pole of the trio it could be cantered.
Basically, have a play around with these pole triangles, taking as many different routes as you can, focusing on riding rhythmically, accurately, aiming to the centre of each pole, and straight. You should feel your horse’s cadence and balance improve as they start to lift their feet higher over the poles, lift through their abdominals, lighten the forehand, improve their proprioception and become more interested in their work.
