You sound like my instructor
She is always saying 'let the horse come up to YOU' when going over the jump. Most times there is a trot rail in front of the jump but this particular lesson there wasn't. I hope I can get some practice in and get better at this...it seems so natural to me now to canter over a cross rail it seems silly that I'm having so much trouble at the trot. I am thinking about leasing the horse I take lessons on but you are not allowed to jump a leased horse unless you're in a lesson so I guess I will have to practice over poles on the ground? Maybe a cavalletti?
