I have seen many people jumping that have their legs far back against the horse's sides, mostly these people who jump high jumps. I have two pictures that demonstrate this, the first and second picture below.
Then I have seen a handful that jump with their legs either right at the girth or just behind the girth like the third picture below.
Now which of these are correct? I have always been told to keep my legs near to the girth, not to slide back against the horses side. But I see most people jumping with their legs far back.
What does everyone else think?
