I've recently began jumping and so far it hasn't been going too well. I just can't seem to keep my balance as my horse goes over the jump. I've been trying really hard to keep my lower leg solid but it seems to fail me more than help me. I've never jumped any higher than 2 feet so far. My horse seems to sense my hesitation when we approach a jump and now likes to stop right before it then do a little bunny hop over it or she stops completely/ runs out. Any help on what I can do to correct myself?
