Take your time with him. Don’t try to hurry. Spend a lot of time with him/her in the stall or on the pasture. Make him/her feel safe next to you. I have a on a meat truck horse and there’s nothing better than realising how much progress you made. It’s all about the time you take. Best tip is to take it slow, don’t rush with all the technical stuff. Obtain the trust and confidence in that horse
Good luck and lots of love ❤️
Take it slow and build a partnership with the horse! I find that when the horse and rider have a bond and work together they can then go on to more training and succeed. I think that a mistake that people make is starting groundwork and establishing “leadership” before they do anything else... the problem with that is that you are often just scaring the horse and with what they’ve been through they need a friend and partner, not a leader.
A lot of flat work do build up muscle in the horse and not a lot of jumping.
