How to perform the Banded External Rotation
- Anchor a light band at elbow height and stand side-on to it with the working arm nearest the anchor, that elbow pinned against your ribs.
- Tuck a rolled towel between elbow and torso if the elbow tends to wander; the upper arm stays put while only the forearm travels.
- Rotate the forearm away from your belly and out to the side, stopping short of where the shoulder would shrug or the trunk begin to twist.
- Return to the start over three to four slow seconds, resisting the band the whole way: the lengthening phase is what this movement is prescribed for.
- Work the prescribed 12 to 20 reps with a band light enough that the final rep still looks like the first one.
Suggested working range: 12–20 reps. Default progression: double progression.
Common mistakes
- •Picking a band heavy enough that the torso swings to help, which hides the work the rotator cuff is meant to do.
- •Allowing the elbow to slide off the ribs so the rep becomes an abduction rather than a rotation.
- •Snapping back to the start rather than resisting the band through a slow three-to-four second return.
- •Adding reps to chase a burn when the stage calls for a specific low-load dose.
Variations & alternatives
