A successful sitting trot requires an understanding of the contributions of both horse and rider.
(1) the rider must understand the sitting trot: NECESSARY reading http://www.rogerguevremont.com/pdfFile/LearningTrot.pdf
(2) rider must maintain firm upper body, no flexibility
(3) DO NOT PUSH foot onto stirrup
(4) some flex in hips to move with the horse
Sitting trot is not for beginners The rider should no longer tilt forward or back when horse starts or stops. If possible learn the sitting trot without stirrups.
