Shoulder 6-Way Isometric Series: A Simple Routine to Strengthen and Stabilize Your Shoulder

Isometric exercises are a powerful way to build strength without moving your joints—perfect for injury recovery, stability training, or everyday shoulder maintenance. The Shoulder 6-Way Isometric Series is a quick and effective routine that targets key muscles around your shoulder joint to enhance strength, mobility, and control.

Each position is held for 6 seconds, and each hold is repeated 6 times. Here’s how to do it:


Step 1: Internal Rotation

  • Place a towel between your elbow and torso.
  • Rotate your wrist inward, pressing it against a solid surface.
  • Keep your elbow steady and close to your body.
  • Hold for 6 seconds, then release. Repeat 6 times.

Step 2: External Rotation

  • Keep the towel between your elbow and torso.
  • Rotate your wrist outward, pressing against a fixed object.
  • Engage your external rotators while keeping your elbow tucked.
  • Hold for 6 seconds, then release. Repeat 6 times.

Step 3: Adduction (Arm Press Inward)

  • Place a towel or small pillow between your upper arm and torso.
  • Gently press your arm inward into the support.
  • Engage your shoulder and chest muscles.
  • Hold for 6 seconds, then release. Repeat 6 times.

Step 4: Abduction (Arm Press Outward)

  • Move your arm about 15° away from your body.
  • Push outward into resistance to activate the deltoid.
  • Keep your shoulder relaxed—no shrugging!
  • Hold for 6 seconds, then release. Repeat 6 times.

Step 5: Shoulder Extension (Arm Press Back)

  • Stand with your back against a wall.
  • Keep your arm at your side with your elbow bent at 90°.
  • Press your elbow and upper arm straight back into the wall.
  • Maintain posture and avoid leaning.
  • Hold for 6 seconds, then release. Repeat 6 times.

Step 6: Shoulder Flexion (Arm Press Forward)

  • Stand tall with a towel or cushion between your arm and torso.
  • With your arm bent at 90°, push your hand forward into a wall or resistance band.
  • Keep your shoulder blades pulled back and your arm still.
  • Hold for 6 seconds, then release. Repeat 6 times.

This series is a great addition to any rehab or warm-up routine. It targets internal and external rotators, deltoids, and scapular stabilizers—all crucial for pain-free, functional shoulders.
