Description

This exercise targets the rotator cuff muscles, specifically the supraspinatus and infraspinatus. The user stands erect with one end of the band secured at waist height. Holding the other end, they rotate their arm 90 degrees outwards.

How to Do Resistance Band Standing 90 degrees Shoulder Extrernal Rotation

  1. 1
    Setup

    Anchor a resistance band securely at waist height to a sturdy object or doorframe. Stand perpendicular to the anchor point, holding the free end of the band with the arm closest to the anchor.

  2. 2
    Setup

    Bend your elbow to 90 degrees, keeping your upper arm tucked against your side and your forearm parallel to the floor, pointing directly forward.

  3. 3

    Keeping your elbow at your side and bent at 90 degrees, slowly rotate your forearm outwards, pulling the band away from your body until it's perpendicular to your torso.

  4. 4

    Briefly squeeze your shoulder blade, feeling the contraction in your rotator cuff, then slowly and with control return your forearm to the starting position.

  5. 5

    Exhale as you rotate your forearm outwards against the resistance, and inhale as you slowly return to the starting position.

Tips

  • Maintain a strict 90-degree bend in your elbow and keep your upper arm glued to your side throughout the movement to isolate the rotator cuff muscles effectively.
  • Focus on the controlled eccentric phase (returning to the start), resisting the band's pull to maximize muscle engagement and strengthen the rotator cuff.
  • Choose a resistance band that allows you to perform the exercise with good form for the prescribed duration without compensating with larger shoulder or back muscles.
  • Lightly brace your core to maintain a stable torso and prevent any unwanted twisting or leaning, ensuring the movement is isolated to the shoulder.

Common Mistakes

  • ×Lifting your elbow away from your side during the rotation shifts the work from the rotator cuff to larger shoulder muscles; keep your elbow tucked in to target the intended muscles.
  • ×Rushing the movement and using momentum reduces muscle engagement; perform each repetition slowly and with deliberate control to maximize rotator cuff activation.
  • ×Twisting your torso to generate momentum indicates the band is too heavy or you're not isolating the movement; maintain a stable, upright posture and initiate movement solely from the shoulder.
