I am riding again after a break for several months so I am a bit out of shape at the moment. My muscles are tight so I do a lot of warm up without my stirrups and I noticed that my seat feels more balanced, it is much easier for me to give leg aids, and I feel more “connected” with the horse. As soon as I pick up my stirrups, I lose all of it… if I try to give a leg aid I can’t feel my calf against the horse as much so I use my heel, which causes me to lose my stirrups.
Other than “keep your heels down”, what else could be a potential cause for riding better without stirrups? Ideally, I am mostly interested in understanding any biomechanical explanation (ie: what muscles or joint play a role in this).
Granted, in my case, my saddle puts me a little bit of a chair position. But finding any used saddles in my size is extremely hard to do, so until I can afford a new one or want to continue the dreaded saga of saddle shopping for more months, there isn’t much I can do about my saddle.
