Spec Ops Swimming Tests: Learning the CSS to get TO and THROUGH Spec Ops Selection

The RULES: First, the 500yd Navy Physical Screening Test (PST) allows for the elementary side stroke, the breaststroke, or the modified side stroke nick-named the Combat Swimmer Stroke. The general theme is that these strokes must be "underwater recovery strokes."
However, beyond the PST (getting accepted into training) will require the addition of swimming and SCUBA diving with fins mostly in open water. 99% of your swimming will be done in fins once you are accepted into the training. So, if you choose to use breaststroke as your PST stroke, you will also need to learn the side stroke with fins to succeed beyond Day 1 of training/selection and get THROUGH the training.

The Combat Side Stroke is about conserving energy and maintaining a low profile in the water. Avoid too many kicks, popping up to breathe, and not gliding long enough to maximize your efficiency. Pay attention to your body position and ensure your movements are streamlined and efficient. Count how many strokes it takes to get across the pool (note distance). Typically, we try to get our folks down to 4-5 strokes per 25-yard pool at a yard-per-second pace. See if you need help with any of the following steps of the CSS in the CSS HELP article series:

Master the Stroke (at 50yd in 50 secs or faster) THEN Get Into Swimming Shape: Spend time in the water, swimming, jumping in, and treading. The more comfortable you are in the water, the more confident you'll feel when executing the Combat Side Stroke during the military swim test. Remember, swimming proficiency takes time, watching videos, practicing, and getting feedback to correct incorrect techniques. THEN you have to get in swimming shape. This will add to your training time, but you can do it quickly if you put in the time 4-5 times a week.
The 50-50 Workout is a workout you need to master in order to get into swimming shape quickly. Here is a set of the 50-50 workout.

Dude - You are not in Swimming Shape and practice with the 50-50 Swim workout below 4-6 times a week:
Keep pushing forward; before you know it, you'll be gliding through the water easily and confidently.

Besides, Swimming with fins will be 90% of all swim training in spec ops diving/rescue swimming selection. You will use the side stroke, CSS, Lead Arm / Trail Arm or Turtlebacking with fins for all open water swimming events. The CSS without fins is nearly identical to swimming CSS with fins.
During Spec Ops Training and Beyond - LATA or CSS with Fins- Another option is the Lead Arm Trail Arm Method used primarily by the Air Force Special Warfare program. While the CSS will be used in the Navy Spec Ops programs. Both will be used when swimming in open water and / or selection testing swims, depending on the branch of service. Here is a side by side video showing the differences:
Many swimmers become members of Special Ops units. These candidates do well in the water with their swimming and treading skills, but gravity is not the swimmer's friend. Load bearing, running, rucking, general strength, speed, and agility on land can break a candidate who never got out of the pool for additional athletic training. Though the skills learned from competitive swimming are great, the need to grow beyond the competitive strokes, learn the tactical strokes, and become a tactical athlete will be needed if you choose this path.

Once you get the contract - congrats! You made it TO the training. Now you must focus on being in the top 25% of your class on Day 1 of the First Phase in as many events as possible because the bottom 75% typically will not make it. That means you now have to train to get THROUGH the training. There is a difference between the two phases of tactical fitness. You can do both at the same time AFTER you have reached optimal numbers on the PST.
After You Pass the PST - Assess Yourself for
Any Other Weaknesses (Assessment Tool)
Your Weaknesses Will Be Exposed IF YOU Ignore Them - During the Recruiting Process and certainly through Prep and BUD/S itself.
Not being prepared for your "dream job" is on you. It takes time to get to the level of being able to crush the PST, and then the follow-on logs, boats, weekly 4-mile runs, and 2 ocean mile swims with fins. Just because you can crush a PST, does not mean anything for the follow on events at BUDS.
Show up on Day 1 of your job interview (PST Test Day) well prepared and be in the passing group at least. Showing up and failing is the wrong attitude and a horrible first impression to your future employer. YES - take it that seriously IF you really want this. After all, it only takes Four Steps to Get Prepared for Special Ops Selection.

Core Mission
-
Tactical Fitness Training For the Candidate / Recruit: Specializing in preparing individuals for military, special ops, law enforcement, and firefighter selection programs (getting you "TO and THROUGH" training).
-
Functional Training for Both Active Duty / Recruits: Utilizing a seasonal tactical fitness periodization system that balances longer workouts of running/rucking, swimming, and calisthenics during the Spring/Summer when days are longer. Then, the focus shifts in the Fall/Winter to lifting (Cals/cardio maintenance) when the days are shorter/colder. This process has 25 years of proven success building tactical athletes who improve in all areas of fitness: strength, power, speed, agility, endurance, muscle stamina, mobility, flexibility, and grip.

- Becoming an Asset for All Types: Even non-tactical athletes want to be of use in situations that require some level of fitness to get through the day. Be an asset, not a liability, in potentially dangerous situations, whether natural or man-made. Fitness can be a common denominator in successfully enduring life-or-death scenarios.

When you start training again, consider the seasonal tactical fitness model. I call it A WAY to train and obviously not the only way to train. But it offers the opportunity to never neglect your weaknesses, improves flexibility and mobility, and puts you at a level of physical ability where you are happy with your overall ability to do just about anything. We have a system where the seasons dictate our training. When it is nicer outside, we tend to run and do more calisthenics. When it is colder and not so nice, we lift more, run less, and still maintain our outdoor activities with shorter runs and rucks. Check it out: Seasonal Tactical Fitness Periodization System.
