Healthy vs Harmful Golf Side Bend

Overview

• Topic: Understanding side bend in the golf swing and distinguishing true lateral bending from hip flexion and spinal rotation.
• Goal: Explain healthy vs. harmful side bend, how movement location in the spine matters, and coaching cues to reduce harmful lumbar side bend.

Key Concepts

• Side Bend Definition

• Healthy vs. Harmful Locations

• Movement Drivers

• Side bend refers to lateral bending seen from a lateral perspective, distinct from flexion/extension.

• Harmful side bend occurs in the lumbar (L) spine when pelvis shifts laterally and the lower spine bends to “rescue” the club.

• Healthy lateral shaping is allowed in the cervical (C) and thoracic (T) spine; those regions tolerate more lateral motion.

• Hip flexion (maintained trail hip flexion) can create the appearance of side bend but often reduces true lumbar lateral bend.

• Upper spiral drive (thoracic/cervical rotation) can create lateral/rotational shape up high while keeping lumbar spine safe.

Observations / Demonstrations

• Neutral lateral posture: sacrum and S1 stacked; minimal lateral bend.
• Poor pattern example: pelvis shoots laterally while rotating, forcing L-spine lateral bend to slot the club.
• Safer pattern example: maintain trail hip flexion through transition; use upper spiral drive to rotate and slot without L-spine lateral bend.
• Visual cues: head remains more centered when upper thoracic/cervical lateral bend handles rotation rather than lumbar.

Practical Cues and Drills

• Maintain hip flexion on the trail side through transition and impact phases.
• Drive upper spiral (chest/T-spine/C-spine rotation) to slot the club rather than shifting pelvis laterally.
• Back-chain dominance (rotate through the chain) keeps head centered and reduces lumbar bending.
• Practice chippy shots while intentionally keeping trail hip flexed to feel reduced lumbar side bend.

Action Items

• Monitor pelvis lateral movement during rotation; reduce any substantial lateral shoot of the pelvis.
• Emphasize trail hip flexion in drills to decrease lumbar lateral bending.
• Develop upper spiral strength/motor pattern to control rotation higher in the spine.
• Use simple chipping drills maintaining hip flexion to ingrain safer movement.

Decisions

• Prioritize zero or minimal lumbar side bend for spinal health.
• Allow lateral/rotation in C/T spine within tolerances, but avoid transferring lateral bending into the L-spine.
