I would definitely keep your leg on and drive them forward. But also make sure you have enough impulsion coming to the jump, and keep your keep your back and shoulders straight.
Thanks everyone I’ll definitl Try when I next jump her. No she doesn’t have any issues concerning her health, she was off training for a few months because she was lame but the vet did a full examination and said she was ready to be worked again. I was told she could just be really lazy and not wanting to ridden due to being out of work for so long, been trying to fix that
Keep your leg on and You might try sitting back and keeping your shoulders back as weight on the horses shoulders makes it hard to take off. This may not be the cause of riding and could be something wrong and would recommend a chiropractor ect.
Oh oh! Check her feet bcos I know there is a disease or something that causes horses refusing to jump bcos it hurts them
Have you checked to make sure nothings wrong body/muscle wise? Sometimes they might be sore somewhere which can affect the way they jump or perform :)
check your distances & your body movements. make sure you're confident as well. keep your leg on and drive with your hips
Agree with Elliott also before Amy jumping do some exercises to encourage your horse to use their hind-quarters more like direct transitions and so on to get her legs working more intensively and has more power in the jump
Use placement poles up to the fence(not just 1! Do at least 3 single stride poles) and grid work to keep the rhythm to the jump and so the horse is always travelling correctly to the jump! This will also help you make sure the horse is in the correct spot for take off if you miss!
Maybe because she as built a tolerance to the whip over time and ignoring it. So I would suggest more hugging your legs and trying clicking to get her over
