I’ve said it before and I’ll say it again - your pelvis needs to MOVE when you are in the saddle.
True “neutral pelvis” is a snapshot in time - it refers to when two bony points on your pelvis line up on the horizontal plane. So when you can draw a straight line on the horizontal between your posterior superior iliac spine (PSIS) and your anterior superior iliac spine (ASIS). And it doesn’t take into account the normal variations in pelvis and hip anatomy of individuals…
When we are walking, our pelvis moves through all three planes of movement: forward and back, side to side, and rotation. During riding when the horse moves under us, our pelvis needs to move through all three planes of movement as well. The type and speed of the horse’s gait, as well as the individual anatomy of our pelvis, will influence the exact pelvic biomechanics during riding.
You don’t want your pelvis to be tipped into anterior or posterior tilt, but neither do you want it to be fixed in a neutral position. All of these positions mean you can’t move your pelvis and hips fully, you can’t access your diaphragm effectively, and you can’t rotate your thoracic spine easily. And that means you can’t move with your horse and you will limit his movement.
So yes, ideally you want to start in a “neutral pelvis” position - but you need to be able to move through range, and have control of that range. You need to be able to access anterior and posterior tilt, and control when you need them. Yesterday I posted a test you can use to assess your pelvis movement, control, and symmetry.
In order to allow that pelvis movement you need suppleness, control, and endurance through your psoas and gluteals. This allows you to move with your horse and absorb his movement.
That’s why I designed the Activate Your Seat exercise programme against the resistance of the bungi. All the exercises target psoas and gluteals through range in all three planes of movement, improving symmetry, strength, suppleness, and balance in the saddle.
