Shoulder Isometric Extension: Strengthen the Back of Your Shoulder with Control

The Shoulder Isometric Extension is a low-impact, high-control exercise that targets the muscles in the back of the shoulder and upper arm. It’s ideal for building strength and stability—especially useful in rehabilitation or posture-focused routines.

How to Perform Shoulder Isometric Extension

What You’ll Need:

  • A wall or other sturdy surface
  • No additional equipment

Steps:

  1. Stand Tall: Position yourself with your back against a wall or sturdy surface.
  2. Arm Position: Keep your arm at your side with your elbow bent at 90 degrees.
  3. Apply Pressure: Gently press your elbow and upper arm straight back into the wall—without moving your torso.
  4. Engage Muscles: Focus on activating the muscles in the back of your shoulder and upper arm.
  5. Maintain Posture: Keep a tall stance and avoid leaning or arching your back.
  6. Hold and Release: Hold the press for about 6 seconds, then release.
  7. Repeat: Perform the hold six times with control.

Pro Tips:

  • Avoid using your back muscles—keep the movement isolated to your shoulder.
  • This exercise is perfect for early-stage rehab or as part of a shoulder warm-up.
  • Keep your breathing steady throughout the hold.

This simple yet effective isometric exercise can help build shoulder stability and prevent injury—all without any movement at the joint.
