Rotation
Rotation is a twisting movement around a central axis, such as trunk rotation during Russian twists or internal/external shoulder rotation.
Definition
Rotation turns a body segment around an axis and is commonly described in the transverse plane. Limb rotation is defined relative to the bone and anatomical position.

Context
Running and exercises include varying rotation and stabilization. Mobility and strength work should follow an assessed need; a fixed angle, frequency or split cannot diagnose limitation or guarantee prevention or performance.

FAQ
Is there one correct technique or dose?
No. It depends on the task, goal, equipment and individual response.

Does one measurement prove an outcome?
No. Acute or field measures require context and do not establish long-term adaptation.

Address thoracic rotation mobility with exercises like the open book stretch, thread-the-needle, and seated thoracic rotations. Aim for at least 40-50 degrees of rotation per side. For hip rotation, include 90/90 hip stretches and controlled hip rotation circles. Repz data showing running pace decline in later segments may indicate that rotational limitations are reducing running efficiency.
