How to Prepare for Special Forces Assessment and Selection (SFAS)

The path to earning a Green Beret begins long before you arrive at Camp Mackall. Success at Special Forces Assessment and Selection (SFAS) is not about being the strongest or fastest individual—it’s about being the most prepared. Preparation requires more than just lifting weights or running laps; it’s about building a body and mind capable of enduring stress, uncertainty, and relentless physical demands.

At 18A Fitness, we designed our 16-Week SFAS Program to help aspiring Special Operations candidates, general fitness enthusiasts, and even those recovering from injuries build the holistic foundation needed to perform under pressure.

The Demands of SFAS

Candidates face long rucks, endless miles of running, strength events, land navigation under load, and sleep deprivation—all while being evaluated on resilience, teamwork, and problem-solving. To thrive, you need to prepare across multiple domains of fitness:

• Efficient Running & Rucking: Covering distance under time and load while minimizing injury.

• Strength Development: Functional strength to carry, drag, and lift in any environment.

• Cardiovascular Endurance: The engine that keeps you moving day after day.

• Mobility & Recovery: Staying durable when others break down.

• Mental Toughness: The confidence built through disciplined, progressive training.

  
  

Building the Right Foundation

The 16-Week SFAS Program emphasizes a holistic approach. Instead of chasing numbers on a barbell or running endless miles, we integrate all components of human performance:

• Running & Rucking: Progressive mileage that improves speed, efficiency, and load tolerance.

• Strength Training: Focused on full-body movements that transfer directly to the demands of selection.

• Mobility Work: Daily routines that reduce injury risk and improve movement quality.

• Conditioning Circuits: Blend strength, endurance, and resilience into realistic scenarios.

• Recovery Strategies: Breathing, stretching, and nutrition protocols to keep you operating at peak.

  
  

A Personal Story

When I first transitioned from Special Forces operations to coaching, I saw countless young men arrive at selection broken down before they ever had a chance to prove themselves. Many trained hard—but not smart. They neglected mobility, ignored ruck preparation, or overloaded themselves with gym-based strength work that didn’t translate in the field.

Over my 26-year Army career—16 of those in Special Forces—and later as the Head Strength and Conditioning Coach at the Special Warfare Human Performance Squadron, I helped thousands of candidates earn their berets. The biggest difference between those who succeed and those who don’t? Preparation rooted in balance and purpose.

Actionable Tips to Start Today

Even if you’re not ready to commit to a structured program, here are some habits you can build now:

1. Prioritize Rucking: Start with shorter distances and gradually increase load and mileage weekly.

2. Run Smarter: Mix interval training with longer aerobic sessions to build both speed and endurance.

3. Train Mobility Daily: Ten minutes of focused stretching or joint work keeps you durable.

4. Lift Functionally: Deadlifts, squats, pull-ups, presses—keep it simple, heavy, and consistent.

5. Fuel Your Body: Eat to perform, not just to train. Prioritize protein, hydration, and recovery.

6. Practice Mental Discipline: Small, daily acts of discipline (cold showers, journaling, fasting) build resilience.

   
   

Who Else Can Benefit?

• General Fitness Enthusiasts: Our program sharpens overall strength, endurance, and mobility—ideal for anyone looking to break through plateaus.

• Those Recovering from Injuries: The mobility and durability focus ensures you rebuild correctly while regaining strength and confidence.
