Method
Body and movement: flexion; extension; rotation; separation; balance
GLOSSARY
This overview connects the basic body movements used in snowboarding — flexion, extension, rotation, separation and balance — and explains how they are observed. For example, a whole-body spin, counterrotation and the board turning under the body are three different things.
Context and distinction
Each movement has its own entry. Describing what the body does is different from naming a trick.

Body and movement: flexion; extension; rotation; separation; balance
Flexion. Reducing a joint angle, such as bending the knees. In riding, identify which joint moves and when; flexion is not automatically the same as leaning forward.
Preparation and setting
A terminology reference: use an existing matching technique for a reproduction lesson.
Execution / application
- Identify the term in one existing movement.
- State its feature and travel context.
- Compare the observable property with its nearest confusion pair.
- Link the exact established lesson.
- Keep disputed source conventions alongside the definition.
Learning and practice
Explain the term in plain English using a source-matched example. This is terminology application, not a new drill for every word.
Errors, limits and corrections
Do not substitute a body pose for a board-mechanics definition or derive movement from a name alone.
Observable checks
The reader can define each listed term and identify what it does not establish.
Extension
Increasing a joint angle. Extension can contribute to a supported departure or terrain response, but its effect depends on support and timing.
Rotation
Turning a body segment or the board about an axis. Record the segment, direction, amount and whether contact with snow or a feature is present.
Separation
A difference in orientation or motion between body segments, commonly shoulders/hips and board. It is not a requirement to force a large twist.
Balance
Organizing the rider relative to current support so the intended movement and recovery remain available. Useful balance changes with slope, acceleration and task.
