Refining Shoulder In

In giving the aids for shoulder in, make sure that your inside leg is rhythmically squeezing to engage the horse's inside hind. First bring the horse's shoulders in, then maintaining a lively impulsion, squeeze rhythmically with your inside leg and keep pulsing down into the inside stirrup. Be careful not to "tap" or "stomp" with your leg, as that can be misinterpreted as the cue for canter. You can reinforce your squeezing leg aid for with the whip to maintain the hind leg crossing over and to maintain the tempo.
