Shoulder Health for Surfers: Prevention and Recovery

The shoulder is the most mobile joint in the human body — and also the most vulnerable. It sacrifices structural stability for range of motion, relying on a complex web of muscles, tendons, and ligaments to hold the ball of the upper arm bone (humerus) in the shallow socket of the shoulder blade (scapula). This design allows the enormous range of movement that makes surfing possible. It also means that the shoulder is susceptible to injury when the supporting structures are weak, imbalanced, or overworked.

Surfing places extraordinary demands on the shoulder. Every paddle stroke involves overhead arm movement under load. Every pop up requires an explosive push from the chest. Duck diving pushes the board down and forward against the force of a wave. Maintaining a deep surf stance throughout a ride demands constant shoulder engagement as your arms counterbalance. Over the course of a two-hour session, you may perform 500 to 1,000 paddle strokes — each one stressing the same muscles, tendons, and joint structures.

It is no surprise that shoulder injuries are the most common overuse injury in recreational surfing. The good news is that the vast majority of surf-related shoulder problems are preventable with a targeted strengthening and maintenance program.

Common Shoulder Issues in Surfers

Rotator Cuff Tendinitis / Tendinopathy

The four rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis) stabilise the shoulder joint during every movement. Repetitive paddling can inflame or degrade the tendons of these muscles, particularly the supraspinatus, which runs through a narrow space between bones at the top of the shoulder.

Symptoms: Aching pain on the front or top of the shoulder, especially when reaching overhead or lying on the affected side.

Shoulder Impingement

When the space between the top of the humerus and the acromion (the bony projection of the shoulder blade) narrows, soft tissues get pinched during overhead movements. This causes pain, particularly during the recovery phase of the paddle stroke when the arm lifts overhead.

Surfers with poor posture (rounded, forward shoulders from desk work or overdeveloped chest muscles) are particularly susceptible because the forward position narrows the impingement space.

Labral Injuries

The labrum is a ring of cartilage that deepens the shoulder socket. Powerful, repetitive movements — like aggressive paddling or duck diving — can tear or fray the labrum. Labral injuries often cause a catching or clicking sensation during movement.

Muscle Imbalance

Paddling primarily trains the pulling muscles (lats, rear deltoids, rhomboids). The pop up trains the pushing muscles (chest, anterior deltoids, triceps). Without conscious effort to maintain balance between these groups, surfers often develop strong pulling muscles with relatively weak pushing muscles (or vice versa), which creates unstable shoulder mechanics.

The Shoulder Health Program

This program has two components: a five-minute pre-surf warm-up and a 15-minute strengthening routine done two to three times per week.

Pre-Surf Shoulder Warm-Up (5 minutes)

Perform this before every session. It takes five minutes and dramatically reduces the stress of the first 50 paddle strokes — which is when cold, unprepared shoulders are most vulnerable.

Arm Circles (30 seconds each direction)

Extend both arms to the sides. Make slow, controlled circles, gradually increasing the size. Forward for 30 seconds, then backward.

Band Pull-Apart (15 reps)

Hold a resistance band at chest height. Pull it apart by squeezing your shoulder blades together. Control the return. This activates the scapular stabilisers.

External Rotation with Band (15 per side)

Hold a resistance band with your elbows at your sides, bent 90 degrees. Rotate your forearms outward against the band's resistance, keeping your elbows pinned to your ribcage. This activates the external rotators of the rotator cuff.

Prone Y-T-W (5 reps each position)

Lie face-down. Extend your arms into a Y shape (overhead at 45 degrees), lift them one inch off the ground, and hold for three seconds. Lower. Repeat in a T shape (arms straight to the sides) and a W shape (elbows bent, hands by your ears). This activates the lower trapezius and rotator cuff in patterns specific to paddling.

Shoulder Crossbody Stretch (20 seconds per side)

Bring one arm across your chest. Use the opposite hand to pull it gently closer. This stretches the posterior shoulder capsule, which tightens from repetitive paddling.

Shoulder Strengthening Routine (15 minutes, 2–3× per week)

Perform on non-surf days or at least four hours before a surf session.

External Rotation at 90 Degrees (3 × 12 per side)

Hold a light resistance band with one arm, elbow at shoulder height and bent 90 degrees ("high five" position). Rotate your forearm from parallel to the floor to perpendicular to the floor, keeping your elbow at shoulder height. Slowly return. This is the gold-standard rotator cuff strengthening exercise.

Internal Rotation with Band (3 × 12 per side)

Anchor a band at elbow height. Stand with the exercising arm closest to the anchor, elbow at your side, bent 90 degrees. Rotate your forearm inward against the band's resistance. Control the return. This strengthens the subscapularis, the rotator cuff muscle most involved in the pull phase of paddling.

Prone I-Y-T Raises (3 × 8 each position)

Lie face-down on a bench or the floor. Perform raises in three positions: I (arms straight overhead), Y (arms at 45 degrees), T (arms straight to the sides). Lift one to two inches, hold for two seconds, lower. These build lower trap and rotator cuff endurance in the exact positions used during paddling.

Serratus Push-Up (3 × 12)

Start in a push-up position. Without bending your elbows, protract your shoulder blades (push them apart, rounding your upper back slightly), then retract them (pinch them together). This targets the serratus anterior, which stabilises the shoulder blade against the ribcage — essential for healthy overhead movement.

Face Pull with Band (3 × 15)

Anchor a band at face height. Pull toward your face, spreading your hands wide. Elbows high and wide. This strengthens the rear deltoids and external rotators in a functional pattern.

Push-Up Plus (3 × 10)

Perform a standard push-up. At the top, push further so your shoulder blades protract fully (your upper back rounds slightly). This extra push at the top strengthens the serratus anterior through its full range.

Side-Lying External Rotation (3 × 12 per side)

Lie on your side with a light dumbbell (or water bottle) in the top hand. Elbow at your side, bent 90 degrees. Rotate the weight upward, keeping your elbow pinned. Lower slowly. This isolates the infraspinatus and teres minor.

Posture and Its Impact on Shoulder Health

Forward shoulder posture — where the shoulders round forward and the chest collapses — is epidemic among desk workers, smartphone users, and (ironically) surfers. This posture narrows the space through which the rotator cuff tendons pass, increasing impingement risk.

Combat forward posture with:

• Thoracic extension exercises — Foam roller extensions, open book rotations, and the thoracic mobility drills in our pop-up mobility lesson
• Chest stretches — Doorway stretches (stand in a doorway with your arm on the frame, lean through) open the pectorals and anterior deltoids
• Scapular retraction habits — Throughout the day, consciously squeeze your shoulder blades together for five seconds. Do this 10 times per hour when sitting at a desk.

When to Rest and When to Seek Help

Not all shoulder discomfort requires professional intervention, but all of it requires attention.

Rest when:

• You feel mild aching after a long session that resolves within 24 hours
• A new exercise causes minor soreness (delayed onset muscle soreness, or DOMS)
• You are fatigued from a week of heavy surf and your shoulders feel overworked

Seek professional assessment when:

• Pain persists for more than a week despite rest
• You feel sharp pain during specific movements (especially overhead rotation)
• You experience clicking, catching, or locking in the joint
• Pain wakes you up at night or prevents you from sleeping on the affected side
• Strength is noticeably reduced in one arm compared to the other

Shoulder injuries can affect your ability to handle ocean safety situations that require strong paddling. A physiotherapist or sports medicine professional can identify the specific issue and provide a rehab plan that gets you back in the water safely.

Integrating Shoulder Health Into Your Surf Routine

Shoulder care is not a separate activity — it is woven into your surf life:

• Before every session: The five-minute warm-up
• Two to three times per week: The 15-minute strengthening routine
• Daily: Posture awareness and occasional stretch breaks
• After heavy sessions: Gentle stretching and ice if any aching

Long-Term Shoulder Maintenance for Career Surfers

Surfing is a lifetime sport, and your shoulders need to last a lifetime. Surfers who train shoulder health proactively in their twenties and thirties avoid the chronic issues that force many surfers to reduce their water time in their forties and fifties.

The principles are simple:

• Pre-surf warm-up every session. No exceptions. Five minutes of activation saves months of rehabilitation.
• Balanced training year-round. For every pulling exercise (paddling, rows), include a pushing exercise (push-ups, overhead press). For every internal rotation movement (the pull phase of paddling), include an external rotation exercise (band rotations). Balance prevents the imbalances that cause impingement and tendinopathy.
• Regular mobility work. Thoracic spine extension and chest opening prevent the forward shoulder posture that narrows the impingement space. Include these in your daily mobility routine.
• Listen to early warning signs. Mild aching after a session is normal. Persistent aching, sharp pain during movement, or weakness in one arm is not normal. Address issues early — a week of rest now prevents a month of rehabilitation later.
• Annual check-in with a physiotherapist. Even if nothing hurts, a professional assessment of your shoulder mechanics can identify developing imbalances before they become injuries. Think of it as servicing the engine that powers your surfing.

Your shoulders are the engine of your paddle and the pivot of your pop up. Take care of them proactively and they will carry you through decades of surfing.
