Cable Shoulder 90 degrees Internal Rotation

Description

How to Do Cable Shoulder 90 degrees Internal Rotation

1. 1
   Setup

   Set the cable pulley to shoulder height. Select an appropriate weight that allows for controlled movement.

2. 2
   Setup

   Stand perpendicular to the cable machine with your working arm farthest from the pulley. Abduct your working arm to 90 degrees, so your elbow is at shoulder height and bent to 90 degrees, forming an 'L' shape.

3. 3
   Setup

   Grab the single-grip handle with your working hand, ensuring your palm faces forward and the cable has slight tension at the start.

4. 4

   Keeping your elbow fixed at 90 degrees and your upper arm abducted at 90 degrees, rotate your forearm inward across your body.

5. 5

   Continue rotating until your hand is in front of your chest or as far as your mobility allows. Slowly and with control, return to the starting position, resisting the pull of the cable.

Tips

• Maintain a stable torso and avoid any compensatory movements from your back or hips throughout the exercise to isolate the shoulder rotators.
• Emphasize a slow and controlled return to the starting position (the eccentric phase) to maximize muscle engagement and build strength.
• Ensure your elbow remains at 90 degrees and at shoulder height; avoid letting it drop or extend, which shifts tension away from the target muscles.
• Exhale as you rotate your arm inward and inhale as you slowly return to the starting position.

Common Mistakes

• ×Allowing the elbow to drop or move forward during rotation shifts tension away from the shoulder; keep the elbow fixed at shoulder height directly in line with your shoulder joint.
• ×Swinging the weight with momentum reduces muscle activation; use a controlled tempo to ensure the target muscles are doing the work, not gravity or inertia.
• ×Over-rotating past your natural shoulder mobility can strain the joint; only rotate as far as comfortable without pain or compensatory movements.
