Shoulder Circles and CARs
Coaching cues
- Stand with the arm at the side; make the largest possible circle with the arm
- Controlled Articular Rotations — go slowly through every degree of motion
- Feel where the range is limited; breathe into the restriction
- Perform both directions; daily practice improves shoulder mobility significantly
Common faults 2
Moving too fast — not a controlled rotation
Speed bypasses the positions of limitation; slow is the entire point.
