What muscles does side lying external rotation work?
The external rotation exercise targets the infraspinatus muscle which is a very important muscle of the rotator cuff. The rotator cuff muscles help to provide some stability for the shoulder joint.
What is an example of external rotation?
Examples of external rotation include: With the elbows at 90 degrees of flexion, externally rotating the shoulder brings the forearm and hand away from the body (Figure 21) Rotating the lower limb at the hip joint to point the feet towards each other (Figure 22)

- Gently swing your arm forward and back. Repeat the exercise moving your arm side-to-side, and repeat again in a circular motion.
- Repeat the entire sequence with the other arm.
Why is shoulder external rotation important?
The rotator cuff muscles – including the external rotators – will provide the shoulder with stability during resistance training exercises. If the rotator cuff muscles are weak, the shoulder will be less stable when lifting weights with heavy resistance.
