How do you make a reining spin faster?

Speed in the spin comes after correctness is confirmed, and attempting to add speed before the horse understands the footwork, body shape, pivot foot, and cue produces a faster version of the wrong thing rather than a correct spin at higher velocity. The horse should first demonstrate consistent body alignment, a reliable pivot foot, correct crossover motion in the front feet, and responsiveness to the start and stop cues at a slow and moderate pace before speed is introduced as a variable. When the foundation is solid, speed is added by increasing the horse's energy level — more leg, more forward drive directed into the rotation — while preserving the cadence and form that were established at the slower pace. A single additional revolution added with correct form and then stopped and rewarded teaches the horse that more energy in the spin produces something the rider wants, rather than producing a correction for losing form. Common mistakes in building spin speed include pulling harder on the inside rein to turn the horse faster, which drives the nose around without moving the shoulder and creates a neck-bending spin without true rotation; adding leg without maintaining the other aids, which breaks down form; and drilling many revolutions at once when fatigue begins to erode the quality. Short sets of correct spins — three or four revolutions with correct form, stopped cleanly, rewarded — build speed more effectively than long sets that start correctly and deteriorate. The horse that develops speed through energy and correct form will spin faster and score higher than a horse whose speed was forced before its correctness was established.
