As the Nation’s premier amphibious force, Marines must be prepared to survive and thrive in any environment—including the water. That’s why Marine Corps Water Survival Training goes beyond checking a box; it builds the strength, endurance, and confidence needed to operate in aquatic environments with full combat gear.
While meeting minimum swim qualifications is mandatory, commanders are encouraged to go further. Comprehensive aquatic training enhances mission readiness and reduces injury risk—both in the pool and on land.
The Strategic Benefits of Aquatic Strength and Conditioning
1. Build Full-body Strength and Power
Water provides 12-14 percent more resistance than air, allowing Marines to combine cardiovascular training and resistance workouts into one session.
- Aquatic training improves muscle strength, size, and power.
- Resistance in every direction challenges multiple muscle groups.
2. Reduce Joint Stress & Prevent Injury
Water’s natural buoyancy supports up to 90 percent of body weight. That means:
- Lower impact on joints, bones, and connective tissues.
- Reduced risk of overuse injuries during high-tempo training cycles.
- Less soreness with aquatic plyometrics, but similar strength gains to land-based plyo.
3. Improve Mobility & Functional Fitness
The depth and support of water encourage greater flexibility and functional movement.
- Multi-directional exercises build balance, agility, and coordination.
- These are essential for tactical performance in unpredictable environments.
4. Accelerate Recovery & Rehabilitation
An aquatic environment is clinically proven to:
- Decrease pain, inflammation, and joint stiffness.
- Promote faster healing post-injury or surgery.
- Enhance blood flow when performed in warm water, speeding up muscle recovery after strenuous training.
Swim Skills Survival Training (S3T) & Water Survival Qualification
The Marine Corps Water Survival Program offers progressive training, from basic skills to advanced survival techniques. This training develops the aquatic competence Marines need to respond confidently in water-based scenarios—whether during operations or emergencies.
