🎯 Theme
Durable movement isn’t built from one quality.
It’s built from three.
Range.
Control.
Force.
This lesson introduces the framework that connects them.
📌 Teaching Objectives
By the end of this lesson you will understand:
• The three pillars that create durable movement
• The most common imbalance patterns seen in clients
• How the Durability Triangle explains movement breakdowns
• How to use the triangle as a simple diagnostic tool
💡 Key Insights
• Most clients become dominant in one movement quality over time
• Common patterns include strong but restricted, mobile but unstable, and strong but lacking control
• Durable movement requires range, control and force working together
• When one pillar dominates, another pillar is usually underdeveloped
• The Durability Triangle gives coaches a simple way to identify movement imbalances
🧠 Coaching Takeaways
• Look at clients through the lens of range, control and force
• When one quality is dominant, test the others
• Strength without range creates restriction
• Range without control creates instability
• Force without control creates vulnerability
📜 Lesson Doctrine
Durability comes from balancing the triangle: range, control and force.
If one side dominates, another side is usually weak.
🔍 Reflection
Think about three clients you currently work with.
Which pillar of the triangle appears strongest for each client?
Which pillar might be underdeveloped?
