Old thread but a good one.
I’m not a bareback rider type. It’s just not something I enjoy and I often think it worsens position faults like a chair seat or collapsing the core for some riders. However, a friend lovingly forced me to hop on her pony over the weekend just to do walk work.
I’ve been struggling with weighting my seatbones evenly. On a standard-sized horse I hadn’t felt what was going on but riding a very petite pony, the difference was something that needed to be addressed. My friend has a wildly round pony and I spent about a half hour doing a ton of squares and teardrops at the walk. Any tension in my legs would clothespin me in a precarious way and dropping a hip going into a turn was instantly dicey. I found it to be very helpful and a great reminder for the dangers of letting my inside seatbone get “stuck in the hole” when a green horse falls into a turn.
