Okay, so I have been trying to learn how to canter properly for a while now without bouncing around like an idiot and it's the most frustrating thing for me. I am having real difficulty trying to figure out how I should move so that I am moving with the horse and not getting catapulted out of the saddle every stride.
I have the pleasure of riding school horses with extremely difficult canters to sit to (according to the instructors) and I'd just like to be able to ride with it so I'm not banging down on the poor horse's back all the time.
Here's a short YouTube video of my riding. I can see I do have a bit of a chair seat as well, could fixing or improving that also help?
