You definatly have to rise out of the saddle going over the realy big jumps. even for just two point position. What does she mean by dont come out of the saddle?
Really ?! Look at some of the top SJers and see how close to the saddle they are over the top of the jump ! Or the eventers. Of course if we're talking Puissance, then the movement is more extreme and bums may be out of saddles. But then we're talking REALLY big jumps and I don't think you're jumping that kind of height
When you go over the jump, your centre of gravity
does need to move (a) to help the horse move up and forward and (b) so it stays over the horse's centre of gravity, which moves up and foward. But actually the movement is quite small and most of it can come from folding your upper body forward.
So what shes means by "don't come out of the saddle" is pretty much exactly that ! Most of us are not supple enough to fully fold and keep our bums in contact with the seat, but you should only need a very small hover, not a fully blown "stand up".
2 point position as I was taught it (bearing in mind there seem to be some differences across the oceans) is a small hover, not standing in your stirrups. If I was more out of the saddle, I would still need to be in balance with the horse and over the centre of gravity, so you would still see some alignment going on, even if it was tilted forward slightly to stay over the horse's centre of gravity in a flat out gallop.
edit: just went to have a quick look at that piccie again. Tho' its not scientific, I think if you make a guess where your centre of gravity is, you will see it is quite a way forward. Then think where the horse's centre of gravity is, and I think you will find your c.of.g is ahead of the horses c.of.g. If you closed the angle in your knees a bit more, I think it would bring your c.of.g back over the horses. Have a look and see if you agree or not.....
end of edit:
Often if you
think bum in the saddle you will close the gap enough.
The other way to think of it is that as you jump your lower leg should really not move and should be giving your position stability. If you try, you'll find its actually quite tough to keep your lower leg still AND stand up like that. The two are linked and you find you get a "virtuous circle" (opposite of a vicious circle
) where as your position improves and becomes more stable, you will feel less tense and more confident, and as you are more relaxed, your position will improve some more !
