Every horse and pony is put together differently, which results in a different technique when jumping. For example, some have a very uphill canter and engaged hindleg which allows them to jump with quite a steep bascule – like a pogo stick. Others, who have more of a horizontal gait, will prefer to take off a bit further away from the jump so their bascule is longer and flatter.
I don't think you should try to change a horse's jump technique too drastically, because you're then working against their physical capacity. However, it is always worth trying to enhance their ability and develop the muscles that will allow them to jump more effortlessly.
One of my clients has a pony who tends to get long in the canter on the approach to jumps and so has a very long, flat bascule. He is tidy with his legs, so the shape his body makes isn't a problem, but when he jumps off a long stride he lands long and flat, so it is tricky for my rider to rebalance themselves, or even turn for the next fence! My aim was to improve my rider's feel for a better balanced canter and teach him to hold the canter together on the approach to fences, which will help their landing and getaway.
The last couple of lessons we've used our warm up time to get a feel for lengthening and shortening the trot and canter. The purpose of working on lengthened strides was to teach my rider the difference between balanced, lengthened gaits and rushing or running onto the forehand. After all, they will need to lengthen the canter in jump offs and on the cross country course. We focused on my rider using his seat to encourage the bigger strides, and feeling that he still had a rein contact throughout.
Next, we turned to shortening the strides, or squashing the pony together to give it a non-technical term. It wasn't all about pulling the reins, but rather a series of half halts with the outside rein and a stiller seat. Oh, and lots of tummy muscles! Over the last few weeks, my rider has really started to get a feel for a smaller striding, bouncier trot and canter.
Now we have to link the flatwork to the jumping. Half of the issue comes from my rider not holding the canter together on the approach, and half of the issue comes from the pony preferring to jump long and flat. So I built a series of three bounce fences, which will encourage the pony to jump in a steeper bascule, and to get a little closer to the fence, as well as to be a little more careful and calculating about his jumping.
We used cross poles initially, and my rider held the canter together in a much more balanced fashion until a couple of strides away from the fence, and even then he didn't fire his pony to the jump. Where the jump wasn't that big, I think my rider felt happier keeping the steadier, smaller canter until the jump.
After they'd jumped a few times we discussed how the grid felt. One time, as my rider correctly identified, they met the first fence on a long stride so had a flat jump then the pony had to really adjust his body in order to negotiate the second and third element correctly. When they had a closer take off point, the grid flowed much better and each bascule was more even.
Their getaway from the jumps was improving because my rider could just sit up and rebalance the canter, instead of having a flat, fast canter and the pony on the forehand, which is far harder to correct. The pony was also more willing to come back to his rider. We also put in a 15m circle after the grid to ensure my rider carried on riding after the jumps, and didn't collapse in a heap after. This also helped the pony rebalance and refocus.
We progressed to uprights, which are more demanding for the pony because he has to pick up his forelegs quicker, and make an even steeper bascule. The first time, they tapped each fence as the pony was a little slow in tucking up, but the second time my rider could feel his pony rounding his back more, and they jumped through soundlessly as the pony was quicker with his legs.
My next challenge is to get my rider riding courses in a steadier fashion (I am of course battling against that boy, gung-ho mentality), taking his time to rebalance his canter between jumps so that his pony approaches in a more uphill canter, which will enable them to jump bigger more successfully and effortlessly. By being more consistent in their canter on the flat and when jumping will also help the pony strengthen these muscles, which will further improve his bascule and technique.
I am really pleased with how this young rider is taking on board all the technical information I'm giving him about how horses jump, and I hope that his understanding of our reasons for doing these exercises will mean he does his homework and will be consistent in how he rides, and what he expects from his pony.
