While I am not a trainer, and I've never even hinted that I could be, I am in essence training my own horses. Poor things. Little do they how good their lives could have been.
With that said, I have to rely on the help that I do get. And while it isn't weekly, I know in my heart of hearts that the training I get is good training. It's correct training. My scores on Speedy offer proof. We've finished each level (Intro, Training, and First) with scores in the high 60s and 70s.
So what is Rollkur exactly? Basically, it is the practice of forcefully pulling a horse's head into an extreme low, deep and round position, often for an extended period of time. That's not what I am doing. And anyone who has ever seen me ride in person knows that.
Instead, what my trainer suggested I do was create a situation where Izzy wants to stretch down. When I flex him to the inside, there is no force. He flexes easily. What he doesn't know how to do is to lengthen his neck. By over-flexing him to the inside, and then flexing him vertically, it is showing him that there is a more comfortable position that he can choose.
Within moments of putting him in this "hyper-flexed" frame, he immediately lowers his head and asks to stretch down. I am NOT holding him in hyper flexion. I let him stretch down, and if he'll take it, I'll give him all the rein.
When I rode him on Friday afternoon, I "felt" how the exercise can do even more for him. As I over-flexed him to the inside and then half halted to flex him vertically, I realized that this straightened him so that I could then push my hands forward and ask for a longer stride.
In no time at all, he started snorting and swinging over his back. I don't think that's what rollkur does.
