Biomechanically, when the bar tilts:
- One shoulder often experiences higher torque,
- Scapular mechanics may diverge side-to-side,
- Trunk rotation increases,
- Stabilisers must resist rotational collapse.
Over time, this may contribute to
- AC joint irritation,
- Pec/triceps imbalance,
- Rotator cuff overload,
- Elbow irritation,
- Spinal rotation compensation,
- Chronic asymmetrical movement patterns.
