I tend to carry my right shoulder lower than the left, probably as a result of carrying heavy bookbags in highschool. I don't do things like that anymore, but the aftereffects are still there. It's nothing extreme, maybe an inch or so, but I'd like to do something about it. For some of the sports I do, straightness and balance are very important. It never bothered me for cycling, but it does for equestrian pursuits. If I'm not sitting straight it adversely affects the way the horse moves, at least for the type of precision riding I'm doing.
I have no idea how to even approach this. My riding coach helps me learn how to compensate for this when I'm actually in the saddle but he thinks it would be good for me to work on the underlying issue out of the saddle. Is there some type of physical therapy that you can do to work on this? Or am I doomed? lol
