The Torso & the Half Halt Concept The upper body, when properly connected, is a balancing rod that shifts the horse off the forehand and onto the hindquarters. When you "brace your back" to half halt, you make your torso firmer still with the abdominals and back muscles working together. Creating the pulse of a good rhythm with your torso keeps the horse from rushing and getting the hind legs too far out behind. When the upper body comes back, the horse feels the weight shift and brings the hind legs more underneath to hold up the rider. This may necessitate coming behind the ver- The half-halting torso tical momentarily in order to use the torso effectively in transferring the horse’s weight back onto the hindquarters. As the horse becomes more supple and learns the language of the torso, the aids become more subtle. But if you start subtle and get no effect, the half halting aid (engaging your torso) needs to be stronger. Advanced riders make these half halting corrections with the torso all the time and very quickly. The correct rider response time is measured in fractions of a second to keep the horse from moving on the forehand or disrupting the rhythm. Like dancers, advanced riders reinitiate their own balance in the torso before the horse has a chance to make an out-of-balance mistake. Self-carriage in horses is achieved when the horse and rider balance together and only minor rider adjustments through the torso, arms and legs are required. A rider with a correct torso self-carries, allowing the horse to move more freely. The horse can then develop strong abdominals and lifts its back. required of him in terms of collection, extension, halting, half halting, etc. The rein and leg aids are secondary to this. Anatomically speaking, the pelvis is influenced by the rest of the torso from above and by the thighs and legs from below. For horses to move fluidly under us, we must lift OUR torsos in a dynamic way, allowing motion to flow through their backs. Even the smallest rider on a big horse can, with sloppy posture, very effectively keep the horse’s back from moving well. The slight tipping forward or backward of such a position also puts additional weight on the horse’s shoulders and the base of the neck. If this occurs, the back of the horse, especially behind the saddle, moves less and less. If the lower back of the horse isn’t mobile and swinging, the hind legs cannot take a long enough step underneath the rider’s center of gravity. The Structure of the Torso Imagine the spine as a set of building blocks (vertebrae) arising vertically out of the pelvis with a bowling ball (the head) perched on top. Now think of the lumbar spine as the bottom five of the blocks. This represents the most flexible part of the spine because it has no rib cage for stability. The lumbar spine must try to support both rib cage and head while counteracting the natural SOFTNESS of your abdominal region and stomach. Flexibility of the lumbar spine is great if you want to bend over to pet a small dog. Flexibility is not good if you want to balance a bowling ball (your head) on top of wobbly blocks (your spine) on top of a bowl (your pelvis) sitting on top of a bouncing object (your horse). Here come your muscles to the rescue. It is muscle power that generates stability in the lumbar and abdominal area and in the torso as a whole. The human postural muscles are arranged in layers that crisscross the abdomen and run parallel to the spine. They even reach under the shoulder blades and up to the head. All these muscles arise out of the upper rim of the pelvis. Additionally the spine itself is interwoven with smaller muscles that refine postural balance, movement and torque. Layered over all these are the latissimus dorsi muscles (lats) that rise out of the low back, fan out on each side of the spine and swoop up under the armpit to attach very close to the shoulder on the FRONT of the upper arm. These two muscles aid in the postural stability of the spine but also secure the upper arms down by your side. 27
