How do people get there horses to free jump. I see people online all the time with there horses free jumping and it seems really fun to do but I have a small arena, a lot bigger than a roundpen so I don't think that I can teach my mare to do it. She loves to jump but everytime I try to free lounge her or something sh goes to the other side of the arena.nd she never stays at the edge or the fence.ow do you get them to free lounge in a space that big? My arena is big enough to do barrels in.
