Training for Depth in the Desert: How We Build Freedivers in Tucson Pools

Living in the Sonoran Desert, we are masters of adapting to our environment. We know how to find beauty in the heat and adventure in the dry landscape. But for those of us who hear the call of the ocean, being landlocked can feel like a limitation.

However, when it comes to freediving—the art of diving on a single breath—living in Tucson is not the disadvantage you might think. In fact, the controlled environment of a swimming pool is actually the superior laboratory for building the skills you need.

While the ocean is where we go to perform, the pool is where we go to train. At 72 Aquatics, our SSI Freediving instructors use the pool to break down the sport into its two critical components: Static Apnea (the mind) and Dynamic Apnea (the mechanics).

1. Static Apnea: Mastering the Mind

Static Apnea is the practice of floating face down in the water, holding your breath for as long as possible. It sounds simple, but it is the ultimate mental game. Without the distraction of swimming or looking at scenery, you are left alone with your thoughts and your physiology.

This is where you learn to understand your body’s “fuel gauge.” In the safety of our pool, we teach you to:

• Overcome the Urge to Breathe: We teach you that the “need” to breathe is actually just a buildup of Carbon Dioxide (CO2), not a lack of Oxygen. You learn to recognize these signals—diaphragm spasms, warmth in the chest—and relax into them rather than panicking.

• The Body Scan: You learn to mentally scan your body, releasing tension from your shoulders, your jaw, and even your tongue. Every ounce of tension burns oxygen; relaxing effectively can double your breath-hold time.

If you can stay calm and hold your breath for three minutes in a pool, doing a one-minute dive to 60 feet in the ocean becomes mentally effortless.

2. Dynamic Apnea: The Art of Efficiency

Dynamic Apnea is swimming horizontally underwater on a breath-hold, usually aiming for distance. This is where we perfect your streamlining and propulsion.

In the ocean, poor form creates drag. Drag burns oxygen. In the pool, we can strip away the variables of current, waves, and depth pressure to focus entirely on hydrodynamics.

• Finning Technique: Are you bending your knees too much? Are your toes pointed? We refine your kick cycle to ensure maximum propulsion for minimum effort.

• Streamlining: We work on your body position, keeping your head tucked and your arms extended to cut through the water like a needle.

By the time you head to the open water, your muscle memory is locked in. You move efficiently without thinking about it, saving your precious oxygen for the dive itself.

3. The Science: CO2 and O2 Tables

Pool training allows for precise, scientific conditioning using “tables.” These are interval training sets designed to expand your physiological limits.

• CO2 Tables: These involve holding your breath for a set time with shorter and shorter rest periods in between. This forces your body to tolerate high levels of CO2, delaying the urge to breathe.

• O2 Tables: These involve holding your breath for longer and longer durations, training your body to function efficiently even when oxygen levels get low.

4. Safety: The Golden Rule

The most critical lesson we teach in the pool is safety. Freediving is safe, but only if you follow the rules. The number one rule is: Never Freedive Alone.

In our SSI courses, you learn the role of the “Safety Diver.” You learn how to watch your buddy, how to recognize the signs of hypoxia (low oxygen), and exactly what to do in the unlikely event of a blackout. Learning these rescue skills in a clear, shallow pool builds the muscle memory that makes you a responsible ocean buddy.

The Transition: From Pool to the Sea of Cortez

So, does pool training really work? Absolutely.

When our students join us for their open water checkout dives—usually at Lake Pleasant or on our trips to San Carlos, Mexico—they are often shocked by how easy the depth feels. Because they have already mastered their breath-hold anxiety (Static) and their finning efficiency (Dynamic), the only new variable is equalization.

Instead of being overwhelmed by the environment, they are relaxed. They glide down to 10, 15, or 20 meters with a smile (well, an internal smile!), enjoying the silence and the marine life.

Start Your Journey in the Desert

You don’t need to wait for your next vacation to start becoming a freediver. You can build your lungs, your mind, and your technique right now, after work or on the weekend.

The SSI Freediver and SSI Advanced Freediver courses are running regularly at 72 Aquatics. Come join us in the pool, discover what your body is truly capable of, and prepare yourself to explore the ocean on a single breath.
