My question is, how long have you been jumping? Have you done a full course?
All 3 videos:
Pick up your hands please! You cannot be functional what-so-ever as a rider, when your hands are that low. You have no where to give, take. No where to ask, be asked. You have no where to go if you need to. Pick them up, close your elbow angle.
When you ride with your hands that low, you cause a domino effect of flat and forward riding. Your hands drop, your shoulders follow. Your shoulders drop, your chest follows. Your chest drops, your seat follows.
You are now, unfunctional.
Also, you are not aiding your horse to be lifted up into your aids - instead, your horse is flat and on his forehand. Which is what happened thorughout all 3 vids. Your horse jumped flat and heavy.
I understand how Coaches want their students to stay in 2 point to the fence, after the fence and between the fence - to teach their students to stay quiet and out of their horses way, but you aren't learning how to be functional as a rider while you are doing this.
While yes, it is a great learing tool to remain put, and remain where you should be while over the fence so that you can learn as to how that feels and should feel - on the other hand, you are not learning how to be functional.
I understand that it will come over time, and you have a great horse who knows how to do his job and does it well, and for that he should be praised, but you also are not learning how to ride effectively on approach, after and between the fences.
So - yes, your form is solid over the fence, but you are not functional what-so-ever between the fences.
Can you see how forward your upper body is? When you are told to remain in 2 point, all of your bodies weight is pushed onto your horses forehand *shoulders*. This not only makes his job that much harder to get over the fence, because he not only is lifting his bodies weight onto his hind end, but he is lifting yours as well - this also encourages a flat and heavy on the front end horse.
This horse, deserves ALOT of praise for getting you over those fences without stopping and veering out. If you were on my guy, he'd of stopped at the base of the fence, and his rider would of kept going.
Eventually, you should beable to sit on all 3 points of your seat *Both seat bones and crotch* with a tall upper body, carried hands, open chest to the base of the fence, while yet, allowing your horse to close the angle for you and lift you out of your tack.
When between the fences - you should sit down and sit up tall instead of remaining in your forward seat.
On a positive note, I am glad that you are on a trust worthy, stead fast horse who does his job properly regardless of what you are not doing in your tack. I am glad that you are learning as to what solid form should be over the fence - now, you need to be learning how to approach the fence and how to ride between the fences through functional form.
