BUD/S Preparation
BUD/S (Basic Underwater Demolition/SEAL) preparation refers to the structured physical training undertaken before entering the Navy SEAL selection pipeline. The Naval Special Warfare Preparatory Training Guide outlines a 26-week progressive program designed to build the endurance, strength, and mental resilience required to attempt BUD/S.
What the 26-Week Program Covers
The official NSW training guide divides preparation into phased blocks that progress from foundational fitness to high-intensity conditioning. Each week prescribes specific workouts across cardio (running and swimming), calisthenics (push-ups, sit-ups, pull-ups), and strength training. The program assumes candidates will test their fitness periodically using the Physical Screening Test (PST) and adjust training loads accordingly.
Why Structured Preparation Matters
BUD/S has one of the highest attrition rates of any military selection program. Candidates who arrive undertrained are far more likely to suffer injuries or drop on request (DOR). A structured preparation plan reduces injury risk by progressively loading the body and ensures candidates meet the minimum PST standards well before they ship to Coronado.
Program vs. Instructional Training
BUD/S preparation is a macro-level training plan — it tells you what to do each day for 26 weeks. The individual components within the plan (LSD runs, interval swims, calisthenics progressions) are the specific training methods that make up each session. Understanding both the overall structure and the individual methods is essential for effective preparation.
Start the 26-week program only after you can pass the PST minimums comfortably. If you can't, spend 4-8 weeks building a base first.

The Physical Screening Test (PST) is the standardized fitness assessment used by Naval Special Warfare to evaluate candidates for SEAL training. It measures performance across five events: 500-yard swim, push-ups, sit-ups, pull-ups, and a 1.5-mile run, each with minimum and competitive score thresholds.
Progressive overload is the training principle of gradually increasing the demands placed on the body over time. In the NSW preparation program, progressive overload is applied systematically — cardio distances grow week over week, calisthenics rep targets scale with PST performance, and strength training loads increase as the candidate adapts.
Naval Special Warfare (NSW) is the United States Navy component responsible for SEAL teams and Special Warfare Combatant-craft Crewmen (SWCC). NSW publishes the official Preparatory Training Guide that forms the basis of BUD/S preparation programs, establishing the standards and training methodologies candidates should follow before entering the selection pipeline.
Long Slow Distance (LSD) training is a cardio methodology that emphasizes sustained, moderate-intensity effort over extended durations. In BUD/S preparation, LSD sessions build the aerobic base required for long swims, runs, and the prolonged physical output demanded throughout SEAL selection.
