Step-by-Step Instructions

  1. Begin at the working sitting trot, tracking right along the long side of the arena.
  2. As you come out of the corner, maintain the bend you had in the corner but continue straight down the long side.
  3. Your horse should be on three tracks: the inside hind leg stepping toward the line of the outside front leg.
  4. Keep your inside leg at the girth to maintain impulsion and bend. Your outside leg behind the girth prevents the haunches from swinging out.
  5. Your inside rein maintains flexion while the outside rein controls the degree of angle. Aim for about 30 degrees from the rail.
  6. Ride shoulder-in for the length of the long side, then ride straight into the corner.
  7. Repeat on the other rein. Most horses find shoulder-in easier on one side than the other.

Common Mistakes to Avoid

  • Too much neck bend without enough body angle, creating neck-in instead of shoulder-in.
  • Losing impulsion because the rider over-uses the reins to create the angle.
  • The angle varying along the long side instead of remaining consistent.
  • The horse drifting off the rail, turning instead of moving laterally.

Variations & Progressions

  • Ride shoulder-in at the walk first to establish the feel before adding trot.
  • Progress to shoulder-in at the collected trot for increased engagement.
  • Use shoulder-in as a preparation for half-pass: shoulder-in to half-pass mid-arena.
Tip: Think of riding the horse's shoulders around your inside leg like wrapping a scarf. The bend comes from the body, not just the neck.
