Let’s talk seat.
These are three common pelvic positions in riding.
There are many others we won’t discuss here today, like lateral roation or pelvic obliquity, they are far more complex than we can cover in a short post.
Let’s start with A.
Anterior pelvic tilt. This rider sits with most of their balance on the front of their pelvis/p***c bone. This causes the back to arch too much. This can be misconceived as a rider sitting up nice at pretty, but…. The riders spine cannot perform much shock obsorbtion and the riders pelvis forces most of the momentum down through the horses shoulder area (the arrow indicates direction of pelvic motion). This restricts the horses front end motion in both elevation and stride length. The horse then begins to pull with its front end and cannot maintain cadence or balance.
B. A balanced pelvis.
The rider is balanced on both seat (sits bones if we use official terminology) bones and the apex of the p***c bone. The arrow indicates the energy flow through our hips as forward and slightly upward. Lifting the horses shoulder and freeing their stride. This allows the back to swing freely and the hind legs to drive up through the movement. This horse can also use its back correctly and this riders seat, once the rider develops feel, will recognize how the horses back is working (or not) and make corrections as needed.
C. Posterior pelvic tilt.
This is VERY common in western riders. In english riding it is referred to as the “chair seat”. Again, the arrow shows us where the pelvic motion goes. It drives straight down into or slightly in front of the horses lumbar area. This causes the horse to drop its back, restricts movement through the back and hinders impulsion from the hind legs. Also, you can just see the compromised, unstable leg position of the rider at the bottom of the photo.
