Extension is an important function and movement available in each joint of your body. It is the opposite of flexion. Fundamentally, it means a movement that increases the angle between two body parts or moves a joint in the direction of straightening. While we won't cover how all joints move into extension this month, we will inspire you to learn more about some of the muscles that move your upper body into extension, give you a sweet short series for your home practice and help you understand the difference between flexion and extension in your spine!

Outside of your body, extension can also mean:

expansion, increase, enlargement, widening, broadening, deepening; augmentation, enhancement, development, growth, continuation.
