My trainer has always had me post trot with no stirrups in order to stregthen my groin muscles. However, I never use my groin muscles when I canter or any other gait (im only sore after no stirrup posting trots). She said that when she canters that she engages her groin muscles and the back of her legs to keep her seat when cantering, I do not do this. Should I lower my stirrups lower so I have to engage my groin mucles?
I have read about sliding back and forth in the saddle when cantering which I am starting to do. Am I using my groin muscles to aid in this movement, as in using them to forcefully push me back and forth in the saddle?
Thank you so much!
