Shoulder-in is the aspirin of dressage – Nuno Oliveira.
In his book, School of Horsemanship, published in 1733, François de la Guérinière describes shoulder-in as the alpha and omega of all exercises for developing suppleness and agility in horses. An exercise used by classical dressage trainers for centuries, unchanged and instantly recognisable, it is one of the earliest lateral movements taught to horses.
Well ridden, shoulder-in provides major benefits in the schooling of horses, essentially the suppling of the horse’s shoulders, preparation for the horse to be placed into their haunches and it trains the horse to move away from the rider’s leg.
The basic principle of shoulder-in is that the horse brings their shoulder away from the line of travel, with the hind legs remaining on the line of travel, and then the horse proceeds stepping slightly sideways in the original direction. The angle may vary from horse to horse, depending on their conformation, suppleness and level of training, but all shoulder in shoulder exhibit the same qualities.
Common faults are;
Have a look at the pictures below, the horses are in the same stride in shoulder-in, but the pictures look quite different. Both horses show a good degree of suppleness but the horse on the right has disengaged his haunches, hollowed his back and is dropping towards his outside shoulder.
