Two-track, also written as two track or travers (depending on the specific movement), refers to a category of lateral ridden work in which the horse moves with its body at an angle to the line of travel, so that its fore and hindquarters follow two separate, parallel tracks through the arena. The result is a horse moving diagonally forward rather than straight ahead, with each leg placing on a distinct line — hence the name.
Two-track work sits at the heart of classical equitation and is central to dressage training. It develops suppleness, collection, and the horse’s ability to step under and across with its hindlegs, which ultimately leads to the engagement and carrying power that separates a trained horse from an unschooled one.
The Core Two-Track Movements
Several lateral movements fall under the two-track umbrella, each placing different demands on the horse’s bending and engagement:
Leg yield. The introductory lateral movement. The horse travels forward and sideways simultaneously, keeping its body relatively straight (with a very slight bend away from the direction of travel). The hindquarters follow directly behind the forehand. Leg yield is the first two-track exercise most horses encounter and is used to test and improve the horse’s responsiveness to the rider’s inside leg pushing it away. It appears in British Dressage tests from Preliminary level upward.
Shoulder-in. The first true collected lateral movement, developed by classical master François Robichon de la Guérinière in the 18th century. The horse bends uniformly through its body away from the direction of travel, with the forelegs on an inner track and the hindlegs continuing on the original track. The inside hindleg steps under the horse’s mass, developing engagement and collection. Shoulder-in is sometimes described as the aspirin of equitation — it is used to supple a stiff horse, re-engage a horse that is running, and improve nearly any other movement through preparatory schooling.
Travers (haunches-in). The horse travels along the track with its hindquarters brought in off the wall, bending through the body towards the direction of travel. This is the first movement where the horse looks into the direction it is going while performing lateral work — a significant step up in collection from shoulder-in. Travers requires the horse to step well under with the inside hind, carrying more weight on the hindquarters.
Renvers (haunches-out). The mirror image of travers — the shoulders travel along the wall while the hindquarters remain outside. Less commonly seen in lower-level tests, it develops suppleness in the opposite direction and is a useful correction for horses that habitually fall onto one shoulder.
Half-pass. The most refined two-track movement in regular competition. The horse moves diagonally across the arena, bent towards the direction of travel, with fore and hindquarters on a single diagonal line and the outside legs crossing in front of the inside legs. Half-pass appears from Medium level in dressage tests and, at Grand Prix level, is performed at the canter in spectacular zig-zag sequences across the diagonal. The quality of a horse’s half-pass — the degree of bend, the engagement, the crossing of the limbs — is one of the clearest indicators of its training level.
Why Two-Track Work Matters
Beyond the arena, the benefits of two-track training translate directly into a safer, more rideable horse in any discipline. A horse that has been schooled through lateral work is more adjustable in its stride, more responsive to the leg, and far better able to straighten when needed — for example, on the approach to a fence or when negotiating uneven ground. Even event riders and showjumpers whose horses will never compete in a dressage arena use lateral work in their flatwork programmes for exactly these reasons.
Frequently Asked Questions
What is the difference between leg yield and half-pass?
Both move the horse forward and sideways, but they differ fundamentally in collection and bend. In leg yield, the horse is relatively straight (or bent slightly away from the direction of travel) and is not required to collect — it can be ridden from relatively early in training. In half-pass, the horse bends towards the direction of travel, must cross its outside legs over the inside legs clearly, and carries significantly more weight on its hindquarters. Half-pass requires collection that only becomes available through progressive training; leg yield is a developmental step towards it.
How do I teach a horse to leg yield?
Start on a circle, using your inside leg just behind the girth to push the hindquarters out onto a slightly larger circle — this is leg yielding in its simplest form. Once the horse responds to that pressure, take it onto a straight line along the three-quarter line and use the inside leg to ask the horse to move towards the wall. Keep the pace forward and rhythmic; a horse that slows or shuffles when pushed sideways is not yet forward enough. Build gradually — a few steps is a success at the start.
Can lateral work cause injury if done incorrectly?
Any work done incorrectly or excessively carries risk, and lateral movements are no exception. Forced lateral work on a stiff or unbalanced horse can create tension through the back and hips, and asking for too much bend too soon risks uneven loading on joints that are not yet conditioned for it. The BHS recommends introducing lateral movements progressively under the guidance of a qualified instructor and ensuring the horse is adequately warmed up before beginning any collected or lateral work.
