I have been training horses for about 3 years now (small town, but I want it to be my profession, I am about to start taking some online college courses) & I am always reading & trying to learn as much as possible to become better at it. But I am not very good at teaching yielding to leg pressure (I'm 5'3 & have the SHORTEST legs ever). I try hard but have not been very successful at it, but have gotten a couple to do it right. I just got through starting a 2 yr old stud under saddle, & when I turned his head one way his body would go the other way. I would use my outside leg lightly at first then increase the pressure until I was making him grunt front nudging him & I would open the inside leg so there would be no pressure there. I don't have a round pen yet but hopefully will be able to get one in the next 6 months or so, but I do all my groundwork on a lunge line in the pastures. I use a mixture of natural horsemanship & my own ways. Its just so frustrating...Am I doing it right? Is there any books or DVDs that could help? There are no really good trainers around here & I can't afford one right now, anyway.

*Sorry Its So Long, But I Needed To Vent To Someone*
Any Help Would Be Greatly Appreciated
