Key ideas in Western Saddle Fitting: The Balanced Tree
- The rib cage provides the rigid lateral support for the saddle bars
- The spine is a suspension bridge not designed for direct vertical pressure
- Western bars distribute weight across the ribs to protect the spinal cord
- Identify the primary weight-bearing structure for a Western saddle
- The lumbar vertebrae lack the support of the rib cage and are highly sensitive
- Weight on the 'No-Go' zone causes the horse to hollow its back and feel pain
- The 18th rib marks the absolute rear boundary for any saddle tree pressure
- Identify the rear limit of the weight-bearing surface
- The scapula slides back under the front of the saddle during a stride
- The gullet must be wide and high enough to never touch the horse's spine
- Placing the tree over the scapula's arc causes 'bridging' and restricted movement
- Pressure on the spinal processes can cause permanent ligament damage
- The 'shoulder blade' needs 2-3 inches of clearance from the front of the bars
- Muscle wasting (atrophy) indicates chronic restricted blood flow from tight bars
- White hairs are a sign of historical friction or extreme pressure points
- Uneven muscle development often mirrors a saddle that doesn't sit square
