BUDS, or Basic Underwater Demolition SEAL training, is twenty six weeks determing who wants and has the mental and physical abilities to become a Navy SEAL. BUDS is broken down in three phases. First phase is physical training and is when the greatest number of recruits drop out. An average BUDS class may have up to 75% dropouts. This first phase ends with Hell Week consisting five and half days of about four hours sleep experiencing war time effects while physical demands are nonstop. Second Phase is combat diving and the final third phase is land warfare.
BUDS training is a place that strips you down to your core to see what's really there. We're going to walk through what that punishing journey looks like, from the first day to the last. This is what it takes to even have a chance at completing BUDS.

What is BUDS Exactly?
BUDS is the foundational training program for all Navy SEALs. Twenty six weeks of pure misery. Its one and only purpose is to find and develop men with the strongest character. These are individuals who will give absolutely everything to finish a mission and support their teammates.
It's a six-month marathon of suffering built to test physical conditioning, mental strength, and water competency. The training pushes you far past any limit you thought you had. Only the most dedicated and resilient will make it through.
This all happens under the watchful eyes of seasoned SEAL instructors or like L.C. Fowler calls them, Coronado gods. They are not there to be your friends, but they are master observers of human behavior. They are there to find the next generation of operators who can perform under the most extreme pressure imaginable.
The Gauntlet Starts Before You Think: BUD/S Prep
The road to a Trident doesn't start on the sunny beaches of California. It starts much earlier, at the Naval Special Warfare Preparatory School in Great Lakes, Illinois. You could think of this as the training before the training.
This two-month program is all about getting candidates ready for the intense physical grind of BUDS. The curriculum starts with a Physical Screening Test (PST) just to see where you stand. From there, the intensity only ramps up every single day, building a foundation of durability.
The entire school ends with another, much harder PST. If you fail this final exam, your dream is over before it even really started. You'll be reclassified and sent to another job in the Navy.

Becoming A Navy SEAL Begins At BUD/S: Not For The Faint At Heart
The Final Prep School Test
This is not your average gym workout. The minimum scores here are serious business. To move on to Coronado, you must pass this test.
While the Navy provides minimum standards, the reality is that you are competing against other highly motivated individuals. The goal is to be in the top percentile, not just to pass. The instructors are looking for dominant performance, not just scraping by.
Below is a look at the minimums versus what is generally considered a competitive score.
| Event | Minimum Standard | Competitive Score |
|---|---|---|
| 1000-meter swim with fins | Under 20:00 | Under 17:00 |
| Push-ups (2-minute limit) | 70 reps | 100+ reps |
| Pull-ups (no time limit) | 10 reps | 20+ reps |
| Sit-ups (2-minute limit) | 60 reps | 100+ reps |
| Four-mile run (boots and pants) | Under 31:00 | Under 28:00 |
These are just the minimums, as noted. According to official Navy SEAL + SWCC standards, most candidates who succeed blow these numbers out of the water. You're not just competing against a standard; you're competing against every other determined candidate there.
Welcome to Coronado: Basic Orientation
If you pass the prep school, you get a ticket to Coronado, California. This is home to the Naval Special Warfare Center. Here, you'll start a three-week course called Basic Orientation.
This period introduces you to the base and the BUD/S lifestyle. Instructors show you the obstacle course, known as the "O-course," and get you used to constant physical training. It's a methodical introduction to the pain that's coming.
You are introduced to surf torture, log PT, and the constant feeling of being wet and sandy. It prepares your mind and body for the official start of First Phase. This is your last chance to acclimate before the real test begins.
First Phase: The Ultimate Test of Willpower
First Phase is seven weeks long, and for most, it's the hardest thing they have ever done. This is the basic conditioning phase. Its whole purpose is to test your physical limits, your comfort in the water, and your mental toughness.
Every week, the physical demands grow. The runs get longer and faster, the swims become more challenging, and the calisthenics sessions feel endless. The only thing a candidate might want to hear is his own heartbeat, a far cry from blocking out the world.
Your performance is constantly measured against the clock on four-mile runs, the obstacle course, and two-mile ocean swims. During this phase, you'll also learn skills like conducting hydrographic surveys. But the main event is the constant physical and mental stress.
Hell Week: Forging Steel
The fourth week of First Phase has a special name: Hell Week. It is a defining event in every SEAL's career and the ultimate gut check. It's five and a half days of continuous training that pushes a man to his absolute breaking point.
Let the numbers sink in for a moment. Over the entire week, you will get about four hours of sleep total. You will run over 200 miles, mostly in wet boots carrying a heavy pack, and you'll do more than 20 hours of physical training per day.
This week is not about being a stud athlete. It is a test of your will and your ability to function as a team when you have nothing left. The instructors are looking for who steps up to lead when everyone is exhausted and miserable.
Successfully finishing Hell Week is proof that you have the commitment and dedication needed to continue on the path. It proves you will not quit on yourself or your teammates, no matter how bad things get. It is an experience that bonds a class together for life.

BUD/S Training First Phase All About Physical Misery
Second Phase: Becoming Comfortable with Being Uncomfortable
Once you survive First Phase, you move on to Second Phase. This seven-week portion of training focuses on combat diving. This is where you learn the underwater skills that are a hallmark of the Navy SEALs.
Are you truly comfortable in the water? This phase is designed to test your confidence in some of the most stressful underwater situations imaginable. You will become a basic combat swimmer, learning both open-circuit (SCUBA) and closed-circuit diving with the Draeger LAR V rebreather.
The phase includes "pool comp," a series of tests in the training pool designed to simulate catastrophic equipment failures. Instructors are looking for a high level of comfort in the water.
If you have any deep-seated fears of being underwater or in tight spaces, this phase will expose them. A candidate who panics or struggles with the water will likely not make it through. Remaining calm and thinking through problems underwater is the core competency being tested.
The Final Stretch in buds Training: Third Phase – Land Warfare
The last part of the initial training is Third Phase, focused on land warfare. This seven-week block covers the fundamentals of operating on the ground. You have made it this far, which shows an incredible amount of dedication.
The curriculum covers a wide range of essential skills. You'll learn about basic weapons handling, demolitions, and land navigation. You will also get extensive instruction in patrolling, rappelling, marksmanship, and small-unit tactics.
To put these new skills into practice, the class moves to San Clemente Island for the second half of this phase. Located about 60 miles from Coronado, this rugged island becomes your classroom.
It's here that you apply everything you've learned about operating as a cohesive fighting unit. Graduating BUD/S makes you a Special Warfare Operator, but you still have a long way to go to earn your Trident.
The Mindset That Gets You Through
It's easy to focus on the jaw-dropping physical standards. But talk to any SEAL, and they'll tell you that BUDS is mostly a mental game. Physical strength gets you to the starting line, but mental toughness gets you to graduation.
Research from experts like Angela Duckworth has shown that "grit" is a powerful predictor of success in these types of challenging environments. You can learn more about her findings on grit and perseverance. The ability to persevere despite setbacks is what separates those who make it from those who do not.

The Only Easy Day Was Yesterday: BUD/S Class 89
The candidates who make it are the ones who decide, long before they get cold and tired, that quitting is not an option. It's an internal commitment they make to themselves and their boat crew. The thought of ringing the bell, which allows a man to quit, does not even enter their minds.
They also learn to break down overwhelming challenges. No one thinks about getting through all of Hell Week at the start. They just focus on getting to the next meal, then the next evolution. This mental strategy of focusing on the immediate task at hand makes the impossible seem possible.
Candidates learn that being a good team member is more important than being an individual star athlete. The man who helps his buddy with his pack is more valuable than the man who finishes the run first. This commitment to the team is what defines the community.
They learn to find humor in misery, sharing a dark joke when they are covered in mud and freezing cold. This coping mechanism is vital for maintaining morale when everything seems to be going wrong.
Conclusion
Surviving BUDS is about much more than physical ability. It is an all-encompassing test of character, resilience, and teamwork. From the early days at prep school to the final land warfare phase, candidates are pushed past every imaginable limit.
The men who succeed are not supermen, but they possess an inhuman amount of grit. They learn to function as part of a seamless team under conditions that would break most people. What emerges is not just a highly skilled operator but a man who has proven he has the unbreakable will required to be a Navy SEAL.
The path through BUDS training is one of the hardest on earth. It is carefully constructed to find the very few who will never, ever quit on their mission or their brothers. That is the core of what it means to get through.
