Im stuggling with my canter still. Im finding if im cantering up a hill or if its slightly up hill I can do a great canter but if im on the flat, slightly down hill or down hill I bounce about like a sack of potatos. This is really getting me down as its hurting my seat bone and it rather uncomfortable. Do I lean slightly back or forward, how do I rock my hips, can you think about what exactly you do when your cantering and how your body moves with the horse in order for your to stay in the saddle and not bounce about then let me know. Im not after being a great rider but I do enjoy cantering and I was hoping to treat myself to a beach ride next month for my birthday but wanted to perfect my canter before so I can really enjoy it. Please advice me.
