Shoulder-in…a.k.a “Abdominal Therapy”

Believing that I was offering some insightful coaching, I nearly assaulted my student with picky corrections about her leg-yield. Make him straighter, I urged. No, now get him bent more. He needs more energy. Wait, not too much—now LESS energy. She rode a few more attempts and I kept picking them apart.

Finally Kay stopped, put down her reins, and gave me a wise smile. “You need to realize that I am happy just to be going sideways at all,” she admitted. Sure, all those other details sounded like worthy goals, but for now the plain act of getting her horse to move sideways when she asked seemed pretty great.

What a good reminder. Exercises like lateral work can be so complicated and nuanced to master that for many learners it feels good to be doing any semblance of them. I remember that stage of tackling the complexities of shoulder-in. Heck, some days, I feel like I am still IN that stage. Like my student, I remember being grateful to have my horse sort of bent, mostly trotting, and kind of moving laterally up the track. Whether or not it was anywhere near exquisite mattered much less.

Today of course I am fixated on nuances and standards of shoulder-in. As I have learned to appreciate its gymnastic effect on the horse, I am grateful for these high standards. Often called ‘abdominal therapy’ by therapists, shoulder-in is not just a classical dressage tool whereby a horse’s balance is elevated and tested. It also served to equalize muscle tonicity on both sides of his body, engages his abdominals, and strengthens adduction muscles in the fore- and hindquarters.

A few days ago, I found myself bouncing through my checklist while riding shoulder-in. It went like this: angle of horse’s body, rhythm, my own posture, poll flexion, line of travel, my position again, frame of horse, angle of his body again. This all happened in about 7 seconds and even though I mostly passed the checklist sufficiently, I broke out in laughter. I could feel my forehead very pinched in concentration, my lips squeezed in a tight line. I was on quality control overload.

I wished momentarily that I could return to that feeling of raw bliss when my horse was doing what felt to me like something unfamiliar and therefore probably a shoulder-in but my instructor was barking: not quite it, not quite it! After indulging in the recollection of that learning curve, I recalibrated my present schooling. I relaxed my forehead and mouth, remembered to be less uptight.

Wherever you fall in the journey of mastering shoulder-in, here are some of my best tips:

  1. Shoulder-in can be equally effective for your horse when schooled in-hand from the ground and ridden under saddle.
  2. When riding, keep your hips parallel with the horse’s hips and your shoulders parallel with his shoulders.
  3. Nine times out of ten, you need to refresh your horse’s energy immediately following a shoulder-in. Think about stepping on the accelerator as you ride forward from the shoulder-in.
  4. Some horses’ improve their lateral movement and freedom when the rider posts the trot as opposed to sitting it. Try both to find out.
  5. Do not over-school shoulder-in with a young or unfit horse. It taxes the stifle, which then strains the lumbar region.
