Main muscles working (thicker lines)
Anchor a band to a post at elbow height and stand with the working side toward it, elbow bent 90 degrees and tucked against your side, hand out toward the anchor.
Keep the elbow fixed against your ribs; a rolled towel between them helps.
Rotate the forearm in across your stomach, like closing a door.
Stop when the hand reaches your belly without the elbow moving.
Return slowly to the start, then switch sides.
Breathing: Exhale as you rotate in, inhale as you return.
Elbow glued to your side
Rotate, don't pull
Slow on the way back
Letting the elbow drift forward or away from the body
Twisting the torso to move the band
Using a band so strong the range shrinks
Use light tension and a pain-free range.
