The Under-Over 25-75/Tread Workout (Dive School Prep and More)

Boost Your Water Confidence for Military Special Ops and Warfare Programs

If you're looking to ace those rigorous military special ops and special warfare diving assessments and selection programs, you've got to build up your confidence in the water. One of the essential swim workouts for those aspiring to make the cut is to choose the drills that make you uneasy - it's key to push your comfort zone with these exercises. Here is what is looks like in circuit form:

Repeat 5-10 times
Tread 1 minute (no hands) - odd sets (1,3,5,7..)
Tread 1 minute with weight in both hands - even sets (2,4,6,8...)
Swim 25m underwater
Swim 75 m any stroke

The 25-75 Under-Over / Tread or Tread/Weighted Tread Workout is a must-have in your training regimen. This workout focuses on underwater swim techniques, treading events, and conditioning. Remember, the objective isn't about holding your breath for longer but efficiently crossing the pool in as few strokes as possible. 

- 25m Underwater Swim. The emphasis here is on efficiency. The goal is to get across the pool in as few strokes as possible, so having a streamlined glide position is most important. Once you've mastered this, you'll find the 25m distance easier than holding your breath and walking. Underwater swim video.


Build up your pull power, kick power, and streamline glide efficiency and do 25m underwater in 3-4 strokes - a telltale sign of above-average swimming form. The conditioning section is in the 75m swim - you can choose from the CSS, elementary side stroke, breaststroke, or freestyle/crawl stroke. I recommend using the stroke you will be tested in when you join the military and try out for these jobs. Navy SEAL, SWCC, EOD, Diver, USMC Recon, Air Force Special Warfare (PJ), Rescue Swimmer too. 

 How it Works:

Tread or Weighted Treading (no hands). This exercise can be particularly challenging, but regular practice is essential to improving your swimming abilities. Start with a 1–2-minute tread (no hands). You can use scissors or work on your egg-beater (alternating breaststroke kick). Try odd /even sets of weighted and non-weighted treading. Try 5-10 lbs treading weight for starters.

25m Underwater Swim - Then swim underwater to the end of the pool if it is 25m in length.   Rest as needed before you do the 25m underwater. 

75m Conditioning Swim - How you swim in this section is up to you. This serves as an opportunity to add conditioning to your pool skills and to practice the stroke that you will be tested on (CSS, Side stroke, Breaststroke, Freestyle)

Before the next set - tread again. Repeat cycle 5-10 times. 

Workout Setup:

Warmup with 500m swim (any stroke / mix)
Repeat 5-10 times
Swim 25m underwater
Swim 75m mix of freestyle and/or CSS
- tread 1 min no hands

If you truly want to excel in military special ops, you will need to put in the work. Just like improving your running requires putting in the miles, mastering swimming technique and reaching the necessary level of swimming conditioning are crucial for becoming a competent swimmer. Repeating the sets 5-10 times is essential, gradually increasing the number of sets as your abilities improve. By putting time and effort into your pool workouts, you'll be well on your way to mastering the water confidence needed for success in military special ops.

 However, remember never to practice these drills alone. Always have a lifeguard at the pool or swim with a partner, especially when attempting underwater swimming. Remaining safe during training is smart training as you prepare for challenges and tests.

Developing Water Confidence: The Key to Success in Military Special Ops

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.
