Swimmer's Shoulder Exercises: Prevention and Rehabilitation

Swimmer's shoulder affects up to 90% of competitive swimmers at some point. The repetitive overhead motion—combined with the unique demands of swimming—creates predictable problems. Smart dryland training prevents injury and speeds recovery when problems arise.

Understanding Swimmer's Shoulder

What Causes It

Volume: Elite swimmers perform 1-2 million shoulder rotations per year

Mechanics:

• Internal rotation dominance
• Scapular dyskinesis
• Rotator cuff fatigue
• Impingement from repetitive overhead motion

Muscle Imbalances:

• Tight: Internal rotators, pecs, lats
• Weak: External rotators, lower traps, serratus

Warning Signs

• Pain during or after swimming
• Pain reaching overhead
• Weakness with arm elevation
• Pain at night
• Clicking or catching sensations

Phase 1: Pain Management (Week 1-2)

If you're currently in pain, start here.

Rest and Modification

• Reduce training volume 50%
• Avoid painful strokes (usually butterfly, backstroke)
• Use fins and kick sets to maintain fitness
• Ice after swimming (15 minutes)

Gentle Range of Motion

Pendulum Exercises:

1. Lean over, let arm hang
2. Small circles, forward/back, side/side
3. 1-2 minutes, 2-3 times daily

Supine External Rotation:

1. Lie on back, arm at side
2. Elbow bent 90°
3. Rotate forearm out (use good arm to assist)
4. 10 reps, gentle

Scapular Setting

Scapular Clocks:

1. Arm against wall at shoulder height
2. Gently press shoulder blade in different directions
3. Think: up, down, in, out
4. Hold each 5 seconds

Phase 2: Strengthening (Week 2-6)

Rebuild the stabilizers before returning to full training.

Rotator Cuff Exercises

Side-Lying External Rotation:

1. Lie on non-painful side
2. Elbow at side, bent 90°
3. Rotate forearm toward ceiling
4. Light weight (2-5 lbs)
5. 15 reps, 3 sets

Prone External Rotation at 90°:

1. Lie face down, arm hanging off bed
2. Elbow bent 90°
3. Rotate forearm up
4. 15 reps each side

Internal Rotation with Band:

1. Band at elbow height
2. Elbow at side, bent 90°
3. Pull band across body
4. 15 reps each side

Scapular Stabilizers

Prone Y-T-W:

1. Lie face down on bench or floor
2. Y: Arms overhead, thumbs up, lift
3. T: Arms to sides, thumbs up, lift
4. W: Elbows bent, squeeze back
5. 10 reps each position

Face Pulls:

1. Band or cable at face height
2. Pull to face, elbows high
3. Squeeze shoulder blades
4. 15-20 reps

Serratus Punch:

1. Lie on back, arm straight up
2. Push hand toward ceiling (shoulder blade lifts)
3. Control back down
4. 15 reps each side

Wall Slides:

1. Back against wall
2. Arms in goalpost position
3. Slide up and down
4. Maintain wall contact
5. 15 reps

Lower Trap Strengthening

Prone T with Thumbs Up:

1. Face down, arms to sides
2. Thumbs pointing up
3. Lift arms, squeeze lower traps
4. Hold 3 seconds
5. 15 reps

Low Trap Row:

1. Band overhead, slightly behind
2. Pull down toward back pockets
3. Focus on lower trap engagement
4. 15 reps

Phase 3: Return to Swimming (Week 4-8)

Gradual return while maintaining dryland work.

Swimming Modifications

• Start with 25-50% normal volume
• Avoid butterfly initially
• Focus on technique (no fatigue swimming)
• Increase 10-15% per week

Continued Strengthening

Band Pull-Aparts:

1. Band at shoulder width
2. Pull apart, squeeze back
3. 15-20 reps

Push-Up Plus:

1. Do a push-up
2. At top, push further (protract shoulders)
3. Feel serratus engage
4. 12 reps

Single-Arm Rows:

1. One arm rows
2. Focus on scapular control
3. 12 reps each side

Prevention Program

For swimmers currently healthy—keep it that way.

Daily Routine (5-10 minutes)

Pre-Practice:

1. Arm circles: 10 each direction
2. Band pull-aparts: 15 reps
3. YTW: 5 reps each
4. Serratus punches: 10 each arm

Post-Practice:

1. Cross-body stretch: 30 sec each
2. Sleeper stretch: 30 sec each
3. Doorway stretch: 30 sec each
4. Lat stretch: 30 sec each

Strength Training (2-3x/week)

Essential Exercises:

1. Side-lying external rotation: 3x15
2. Prone YTW: 3x10 each
3. Face pulls: 3x15
4. Push-up plus: 3x12
5. Band pull-aparts: 3x15
6. Serratus punch: 3x12 each

Stroke-Specific Considerations

Freestyle

• Most rotator cuff stress at hand entry
• Focus: External rotation strength
• Prevention: Avoid crossing midline at entry

Backstroke

• Impingement at start of pull
• Focus: Scapular stability
• Prevention: Don't hyperextend entry

Butterfly

• Most demanding stroke for shoulders
• Focus: Everything—rotator cuff, scaps, thoracic mobility
• Prevention: Limit volume when fatigued

Breaststroke

• Usually easier on shoulders
• Use as recovery stroke
• Watch for neck/low back issues instead

Stretching and Mobility

Essential Stretches

Cross-Body Stretch:

1. Arm across body at shoulder height
2. Pull gently with other arm
3. Hold 30-60 seconds

Sleeper Stretch:

1. Lie on affected side
2. Shoulder and elbow at 90°
3. Push forearm toward floor
4. Hold 30-60 seconds

Doorway Stretch:

1. Forearm on door frame
2. Step through doorway
3. Different elbow heights
4. Hold 30 seconds each position

Lat Stretch:

1. Arm on wall or doorframe
2. Lean away
3. Feel stretch along side
4. Hold 30-60 seconds

Thoracic Mobility

Foam Roller Extension:

1. Roller under mid-back
2. Hands behind head
3. Extend over roller
4. 2 minutes

Quadruped Rotation:

1. On hands and knees
2. Hand behind head
3. Rotate elbow up toward ceiling
4. 10 reps each side

Common Mistakes

Training Errors

• Too much volume too soon
• Swimming through pain
• Neglecting dryland work
• Poor technique when fatigued

Dryland Errors

• Heavy bench press (internal rotation bias)
• Overhead pressing with poor form
• Neglecting external rotation work
• Skipping scapular exercises

When to See a Professional

Get evaluated if:

• Pain persists >2 weeks despite rest
• Weakness with arm elevation
• Pain at night disrupting sleep
• Numbness or tingling
• Previous shoulder surgery

Summary

Swimmer's shoulder is preventable and treatable:

1. Balance the shoulder - Strengthen external rotators and scapular stabilizers
2. Maintain mobility - Stretch internal rotators and pecs
3. Don't swim through pain - Early intervention prevents chronic problems
4. Technique matters - Poor form + high volume = injury
5. Dryland is essential - Not optional for serious swimmers

5-10 minutes of daily shoulder work protects your shoulders for thousands of pool hours.
