Recommended Exercises for the Unstable Shoulder

Shoulder instability can feel like carrying a heavy burden, limiting your ability to perform everyday tasks or enjoy your favorite activities. From reaching for something on a high shelf to playing sports, an unstable shoulder can disrupt your life—and it’s more common than you may think. Fortunately, with the right exercises and proper guidance, strengthening your shoulder is within reach.

If you're struggling with shoulder instability, this blog will provide key insights into why it happens and recommend effective exercises you can incorporate into your routine. Plus, we’ll explain how physiotherapy in Winter Springs, FL, can further support your recovery.
 

What Causes Shoulder Instability?

The shoulder is one of the most mobile joints in the human body, but that mobility comes with its trade-offs—it’s also one of the least stable joints. Shoulder instability occurs when the structures that support the shoulder joint, like the ligaments, muscles, or capsule, are injured or weakened. This can lead to the joint slipping out of place (subluxation) or even dislocating entirely.

Common causes of unstable shoulders include:

• Trauma or Injury (e.g., falls, sports injuries, or accidents causing a dislocation or weakening of the joint).
• Repetitive Overuse in activities like swimming, tennis, or lifting weights. These movements can stretch or weaken the stabilizing structures over time.
• Genetic Factors (e.g., hypermobility or naturally loose ligaments which make the joint less stable).

For many people, addressing shoulder instability begins with movement-focused rehabilitation.
 

Benefits of Exercise for Shoulder Stability

Exercise tailored for shoulder instability serves several essential functions, such as:

• Strengthening the rotator cuff muscles, which play a huge role in stabilizing the joint.
• Improving flexibility and range of motion without compromising stability.
• Rebuilding neuromuscular control, helping your body “remember” how to keep the joint secure during movement.
• Increasing overall strength in supportive muscles around the shoulder blade, such as the traps and serratus anterior.

Think of targeted exercise as a way to rebuild trust in your shoulder—you’re giving it the tools it needs to perform safely and efficiently.

Now, let's look at specific exercises you can try.
 

Recommended Shoulder Stabilization Exercises

Before we begin, remember to consult a physical therapist or medical professional, especially if you're dealing with acute pain or recovering from recent shoulder dislocation. For those in Winter Springs, FL, we at B Physical Therapy are happy to provide personalized guidance.

1. Shoulder Blade Squeezes

This exercise targets the scapular stabilizers, key players in shoulder control.

1. Sit or stand with your back straight.
2. Squeeze your shoulder blades together as if you're trying to pinch a pencil between them.
3. Hold for 5 seconds, then release.
4. Repeat 10-12 times.

2. External Rotations with Resistance Bands

Your rotator cuff muscles, responsible for much of the shoulder's stability, will get a great workout here.

1. Attach a resistance band to a steady surface.
2. Stand with one side facing the anchor point and hold the band in your hand (elbow bent at 90 degrees).
3. While keeping your elbow tucked to your side, pull the band away from your body, rotating outward.
4. Slowly return to the starting position.
5. Perform 2 sets of 10-15 repetitions for each arm.

3. Wall Slides

This exercise not only strengthens your shoulder but also improves range of motion.

1. Stand facing a wall with your forearms placed on it.
2. Slowly slide your arms up the wall, keeping slight pressure against it.
3. Pause once your arms can’t comfortably rise any higher and return to the starting position.
4. Repeat 8-10 times for 2 sets.

4. Bear Plank Shoulder Taps

Great for both shoulder stability and core activation.

1. Begin in a plank position with your shoulders aligned over your wrists.
2. Without twisting your hips, lift one hand and tap the opposite shoulder.
3. Alternate sides for 10-15 taps per shoulder.
4. Perform 2 sets.

5. Sidelying Internal Rotations

This focuses on strengthening the often-neglected subscapularis muscle.

1. Lie on your side with your bottom arm bent at 90 degrees, holding a light weight.
2. Slowly rotate your hand toward your stomach.
3. Return to the starting position.
4. Perform 10-15 reps for 2 sets for each arm.

6. Serratus Punches

This exercise activates the serratus anterior, important for shoulder blade stability.

1. Lie on your back with a light weight in one hand.
2. With your arm extended toward the ceiling, “punch” upward by lifting your shoulder blade off the floor.
3. Slowly lower back down.
4. Do 2 sets of 15 repetitions for each arm.

7. Isometric Shoulder Holds

This low-risk exercise builds basic muscle endurance.

1. Hold a small weight in one hand, with your arm extended outward to shoulder height.
2. Hold for 10-15 seconds before lowering the weight back down.
3. Repeat for 8-10 reps each side, working up to longer holds as you progress.
    

When to Seek Physiotherapy

While home exercises are a great starting point, working with a physiotherapist can take your recovery to the next level. A skilled professional will not only tailor a program specifically to your needs but will also help identify and address any underlying biomechanics issues or muscle imbalances.

Staying Ahead of Shoulder Injuries

The best medicine is often prevention. If you're an athlete or perform repetitive shoulder movements for work, incorporate warm-ups, body alignment checks, and strength-training exercises like the ones above into your routine.

And remember, ignoring shoulder instability or relying solely on rest without strengthening can worsen the issue over time. Stay proactive, and don’t hesitate to consult a professional when needed.
