This!!! I could not agree more. Great read.
Still lunging as a primary form of exercise?
This movement research helps explain why repetitive circling is strongly associated with strain patterns in the equine spine.
The horse’s vertebral column is regionally specialized:
• The cervical spine is the most mobile region and absorbs a large proportion of flexion, extension, lateral bending, and rotation.
• The thoracic spine is comparatively restricted due to rib attachments and its role in trunk stability and force transmission.
• The lumbar spine functions primarily in load transfer and propulsion rather than large segmental motion.
When a horse is worked repeatedly on small circles, the majority of available motion is forced into the cervical region while the more stable thoracic and lumbar regions contribute less.
Over time, this concentration of movement can increase mechanical stress on cervical joints and surrounding soft tissues, which helps explain the high prevalence of neck pain and arthritic change observed clinically.
Although this biomechanical research is not new, it is still frequently overlooked in conventional training systems.
The key takeaway is simple:
The horse is anatomically designed for forward locomotion and large, variable curves across terrain, not continuous tight circling.
If we want soundness and longevity, exercise selection must reflect biology, not tradition.
