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.
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!
