🎯 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?
