eek advice for a friend?

My friend and I take hunter jumper lessons together, and she had a quetion for me that I didn't know exactly what to tell her. We both ride thoroughbreds, me on speckles and her on doodles. When doodles jumps, he does so with all four feet, either that or he just flies through them not even paying attention to his form, etc. our instrutor tells her she needs to get him to roll back, but everything she's tried doesnt work. Does anyone have any tips I could give her?

Thanks

hmm I would just say tell her to take things at a slower pace with him. I can't exactly help you much considering I don't jump myself but I do love it and wish to jump one day so I read up on it alot. Well that's the best advice I can give you at the moment I hope everything works out well.

Thanks :) i'll let her know

Anyone else have any advice?

Try doing some grid work.
