Stretching for Swimmers: Before, During, and After Training
Quick summary: Before swimming: dynamic stretches (with movement) for 3-5 minutes. After swimming: static stretches (hold 20-30 seconds) for 10-15 minutes. Never do static stretches before training: they reduce muscular force by up to 8%.
Stretching in swimming is fundamental for injury prevention, recovery, and flexibility improvement — especially for shoulders, ankles, and thoracic spine. But WHEN matters as much as HOW: stretching wrong or at the wrong time can hurt your performance.
Dynamic vs static: when to use each
| Type | When | Duration | Effect |
|---|---|---|---|
| Dynamic (with movement) | BEFORE swimming | 3-5 min | Activate muscles, increase range of motion, prepare for effort |
| Static (hold position) | AFTER swimming | 10-15 min | Improve flexibility, accelerate recovery, reduce muscle tension |
Dynamic stretches before swimming
These exercises are part of the dryland warmup:
- Arm windmills: Rotate arms like a windmill, alternating forward and back. 20 reps per arm.
- Chest openers: Arms in cross, bring them forward crossing and open again. 15 reps.
- Leg swings: Support on wall, swing leg forward-backward without forcing. 10 each leg.
- Trunk rotations: Arms extended, rotate torso side to side. 15 each side.
- Lunges with twist: Take a long step and rotate trunk toward the forward leg. 8 each side.
Static stretches after swimming
Hold each position 20-30 seconds without bouncing. Breathe deeply.
Upper body
| Stretch | Muscle | How | Time |
|---|---|---|---|
| Cross-body arm | Posterior deltoid | Bring straight arm across chest with other hand | 30 sec/side |
| Hands clasped behind | Pectoral, biceps | Interlace hands behind and raise arms | 30 sec |
| Triceps stretch | Triceps, lat | Arm behind head, press elbow | 30 sec/side |
| Doorframe opener | Pectoral, anterior deltoid | Arm on doorframe, rotate body away | 30 sec/side |
Lower body and core
| Stretch | Muscle | How | Time |
|---|---|---|---|
| Quad stretch | Quadriceps | Standing, pull heel to glute | 30 sec/side |
| Hip flexor (low lunge) | Hip flexor | Knee on ground, advance other leg | 30 sec/side |
| Butterfly (seated) | Adductors | Soles together, press knees | 30 sec |
| Ankle stretch | Tibialis anterior | Kneeling, sit on heels | 30 sec |
Key swimming flexibility: ankles
Ankle flexibility is one of the most limiting factors in the swimming kick. A rigid ankle generates water resistance instead of propulsion. Daily exercises:
- Sitting on heels: 2 × 30 seconds daily.
- Writing the alphabet with your foot: Full ankle mobility.
- Swimming with short fins: Naturally forces plantar extension.

Paso a paso
- Pre-workout: dynamic stretches (5 min) — Perform arm swings, shoulder circles, hip rotations, and leg pendulums. 10-15 reps per exercise. Always with continuous movement, never holding position.
- Shoulders and rotator cuff — Post-workout static: arm crossed in front of chest, hold 25 seconds per side. Then hand behind back with towel for internal rotation, 25 seconds. 2 repetitions.
- Lats and pectorals — Rest hands on pool edge or wall, lean trunk forward and let chest drop. Hold 25 seconds. Feel the opening in lats and pectorals.
- Ankles and calves — Seated with legs extended, point toes forward (plantar flexion) hold 20 seconds. Then pull toward you (dorsiflexion) 20 seconds. Improves kick.
- Thoracic spine — Lying face up with foam roller under mid-back, extend arms overhead. Roll slowly up and down for 30 seconds. Improves body roll and rotation.
Preguntas frecuentes
Should I stretch before or after swimming?
Before swimming: dynamic stretches (with movement) for 3-5 minutes to activate muscles. After swimming: static stretches (hold position 20-30 seconds) for 10-15 minutes. Never do static stretches before training: they reduce muscular force by up to 8%.
How long should I hold each stretch?
Post-workout static stretches should be held 20-30 seconds per position, performing 2-3 repetitions per muscle group. Pre-workout dynamic stretches are continuous movements of 10-15 reps each. Don't bounce or force range of motion.
What muscles are most important to stretch for swimmers?
Priority groups: shoulders and rotator cuff (injury prevention), lats and pectorals (stroke amplitude), ankles (flexibility for efficient kick), and thoracic spine (rotation and body roll). Shoulders are the most critical due to stroke repetitiveness.
