Why am I riding crooked in the saddle what is it effecting?

Riding crooked in the saddle — sitting consistently off-center, with one seat bone weighted more heavily than the other, one hip further forward than the other, or the whole upper body rotated to one side — is one of the most common and most consequential position problems in everyday riding. The saddle, the horse's back, the horse's movement, the quality of the aids, and the horse's balance are all downstream of the rider's position, which means a crooked rider cannot produce a truly straight horse regardless of how correctly the specific aids are applied. The causes of crookedness in the saddle are almost always in the rider's body rather than in the riding itself. The body that arrives on the horse carries the accumulated asymmetries of its physical history — scoliosis that positions one hip higher, hip flexor tightness greater on one side, a leg length discrepancy that tilts the pelvis, old injuries that have created compensatory movement patterns, and the habitual postural asymmetries of dominant-hand life. A rider who sits crooked on a horse is almost always a rider whose body sits crooked in a chair. The effect on the saddle and the horse's back is immediate and physical. A rider sitting to the left loads the left panel of the saddle more heavily than the right. Over time this asymmetrical loading compresses the left panel's flocking more than the right, which makes the saddle progressively less level, which makes the rider's crookedness progressively worse in a self-reinforcing cycle. The horse's back muscles on the heavily loaded side become tighter and more developed from carrying the disproportionate weight. The effect on the horse's movement follows directly from the weight distribution. A crooked rider's weight falls to one side of the horse's center of balance, producing the consistent drift, the falling in on circles, the resistance to bending in one direction, and the uneven contact in the two reins that are the characteristic symptoms of a horse carrying a crooked rider. No amount of specific rein or leg correction of the horse's crookedness will produce lasting straightness while the weight distribution causing the crookedness remains unchanged. Video from directly behind and directly in front of the horse reveals the shoulder height, the hip position, and the overall tilt of the rider's body in a way that mirrors and ground observers can confirm. A physiotherapist or experienced instructor who evaluates the rider's movement patterns off the horse as well as on it provides the most complete picture of what is causing the crookedness and what combination of physical therapy and on-horse awareness work will address it most effectively.
