So I was watching some high-level showjumping on Youtube tonight.
This video in particular haha. Anyway, I noticed that the riders sit to the fences and then throw themselves over at the last moment. In fact, at 2 min 30 seconds in the video, I think the lady announcer expresses surprise that the rider hand-gallops to the fence. Now, me only jumping 2 feet, I am obviously am missing something because my trainer has me hand-gallop to every fence. She says that if I sit to the fence, I'll make a big drastic motion and could get left behind.
So my question to you all is: why do showjumpers sit (or at least, it looks a lot like sitting or crotch-sitting) to the fences? Do hunters do this as well?
