CARs — Controlled Articular Rotations — are slow, deliberate circular movements that take each joint through its full available range of motion. Think of them as daily maintenance for your joints: they preserve range, improve synovial fluid circulation, and give you real-time feedback on where restrictions live.

Fitness Considerations

CARs are the closest thing to a daily minimum for joint health. They take 5–10 minutes and can be done anywhere — morning routine, between meetings, before a workout. If you do nothing else from this library, do CARs.

The “controlled” in CARs is the operative word. Move as slowly as possible through the largest circle your joint allows. If you speed through them, you bypass the neurological input that makes them effective. Aim for 5–10 seconds per rotation.

To truly isolate a joint during CARs, create tension in the rest of your body — squeeze your fists, brace your core, lock your stance. This “irradiation” prevents compensation from adjacent joints, ensuring the target joint does all the work.
