How do I master the turn on the forehand with leg yields?

Mastering the turn on the forehand and the leg yield as connected exercises requires understanding not just how to execute each movement individually but how they relate to each other in the development of the horse's lateral education — because they are not separate skills so much as two expressions of the same fundamental concept applied in different ways. The turn on the forehand teaches the horse to move his hindquarters away from a single leg in a relatively stationary context. The leg yield takes that same response and channels it forward, asking the horse to move away from the leg while maintaining impulsion and rhythm. The turn on the forehand comes first in the sequence because it isolates the response. At the halt, apply one leg behind the girth with a clear, steady pressure and wait for the horse to step his inside hind leg away from that pressure. Your outside rein needs to be soft and allowing — a tight outside rein prevents the hindquarters from swinging around and creates a confused, bracey response. Your inside rein asks for just a slight flexion toward the direction of movement. Build gradually until the horse will complete a full half-circle of the hindquarters around the front end in response to a light, consistent leg aid with no resistance, no rushing, and no bracing. The transition from turn on the forehand to leg yield is where many riders lose the connection between the two exercises. The leg yield takes the same lateral response — hindquarters moving away from the leg — and adds forward motion so that both ends of the horse are traveling simultaneously. Think of it as a turn on the forehand that is also going somewhere — the same leg behind the girth, the same slight inside flexion, but now your inside leg at the girth is also maintaining forward impulsion and your outside rein is shaping the direction of travel. The most common failure points are losing the front feet in the turn — the horse drifts forward rather than pivoting — and losing either the forward motion or the lateral component in the leg yield. Rhythm is the barometer of correctness. A leg yield with good rhythm is a horse that is truly through, balanced, and responding correctly. When the rhythm breaks, ride forward on a straight line, re-establish the tempo, and ask again with a slightly reduced demand.
