I am a horse trainer. I always take it slow. Lots of praise. You don't want to push them to hard or it can break their trust in you. If you sense it start to go badly do something the horse knows how to do and end it on a good note and just pick up the next day, just a little slower.
Well I have a horse and when you get bucked off get back on so he knows your the boss and your not just going to give up. Or you could try the easy way of bonding and he might just let you on without fuss.
