This reminded me of the Spanish Riding School (lots of photos and info. to come), where in some of their schooling jumps they have to ride the horses with no stirrups! It was amazing to watch, the horses were beautiful and so well trained!
I will talk more about the 3 different types of movements the horses do in this video in later posts. I particularly liked how calm the horses were when performing these movements and they just got them to sit more onto the hindlegs to prepare for it.
I find trotting hard enough with no stirrups, when I canter I try and walk as little trot as possible in between! I used to like jumping with no stirrups and bareback but don't think I would like it as much these days!
