In order to keep your shoulders back while riding, you have to train your muscles to hold in that spot. If you use a brace or other artificial device, you are teaching those muscles that they don’t have to do anything because now the device is working and taking over from the small amount those lazy muscles were doing. So most likely things will get worse, not better and you’d have to wear the brace all the time.
Two things seem to help me. First is thinking of my armpits down. Second is feeling my elbows by my sides, and controling my hands via my elbows.[/QUOTE]
I do agree that being held in place can be an issue. Instead, focus on correct use of muscles for the best function matters.
At the root of everything is proper use of various muscles to best ride and move with our horses. “Shoulders back” was defined for centuries men riding, where movement within the hips/pelvis to move with the horse is typically not an issue, but the lack of core use due to hunching more often can be.
For women, thinking shoulders back can lock the back and hips and cause a sway back - putting women on their crotches instead of in a neutral seat, blocking motion, shoulders behind pelvis causing them to pull on the horse’s mouth unconsciously, and causing back pain to riders. For some with more mobility, shoulders back helps them have better posture and correct alignment rather than hunching. I’m one of the former and a device to force my shoulders back would be a very bad thing. Instead, I work on lifting my rib cage to clear space for my hips to move. At work, I put my keyboard higher than people say you should because it gets me sitting up straighter instead of hunching - the supposedly ergonomic posture really makes you slouch.
So they’re kind of light to me… my trainer made me ride with a cinderblock when I was trying to understand how to use my core to ask for uphill carriage from my horse.

I could only walk and trot in that, but it really identified the muscles I needed to keep my alignment and allow movement with my horse. He also had me walk with it off my horse. It’s not something you can do for more than a few minutes, but it helps you identify the muscles to use. After that, an equicube can be the reminder but is light enough to continue to use w/t/c through a ride.
