- 4 min read
Welcome to the freedive.hk learning zone!
Are you ready to embark on your AIDA 2 freediving journey? Before we head out for our open water sessions (where the AIDA 2 minimum depth requirement is 12 meters), building a solid foundation on land will make your learning process much smoother and more enjoyable.
Whether you are joining our yoga sessions, we have created this complete "Video + Text" home training guide to help you build muscle memory. Please make sure to set aside some time to practice on land before attending your practical yoga and equalization class!
🎥 Part 1: Home Training Video Tutorial
⚠️ IMPORTANT SAFETY WARNING: NEVER PRACTICE BREATH-HOLDING IN WATER ALONE! Breath-holding in water carries the risk of a blackout. All breath-hold exercises without a certified instructor present MUST be done on dry land (e.g., on a bed or a sofa).

📖 Part 2: Core Techniques Step-by-Step Guide
After watching the video, follow these detailed text instructions to refine your techniques and ensure you are doing every step correctly:
I. The Art of Breathing: One Full Breath & Yoga Breath
Before we hold our breath, we need to learn how to maximize our lung capacity. Mastering the full yoga breath step-by-step is essential for every freediver:
Chest Breathing: Take a normal, deep breath. In yoga breathing, this primarily involves the expansion of your chest.
Tidal Breath (Belly Breathing): Next, try a normal, calm breath. This is purely belly breathing. As you inhale, only your belly should rise; your chest should remain completely still.
Full Yoga Breath: Now, combine both. Take a long, slow, and shallow breath through your mouth. Fill your belly with air first, and then continue inhaling to fill your chest. This entire inhalation process can last up to 15 seconds!
II. The Key to Easy Descents: Frenzel Equalization
Equalization is a common hurdle for beginners. The Frenzel maneuver is a highly efficient and safe technique. We can break it down into four progressive steps:
Mouth Fill (Experiencing Equalization): Fill your mouth with air (puff out your cheeks). Try to push the air towards your ears until you feel them "pop" and equalize.
Cheek Squeeze (Isolating the Diaphragm): Fill your mouth with air again. Note: You must lock your airway (close your glottis) at this point! You can imagine the feeling of stopping halfway through a swallow, or try looking down (tucking your chin to your chest). These actions naturally help lock the airway.
💡 Why lock the airway? If you look up and squeeze your cheeks, the air will easily slip back into your lungs. If your airway is locked, the air has nowhere to go but into your ears, achieving equalization. Once locked, try to simply squeeze your cheek muscles inward to push the air into your ears. The goal here is to learn how to equalize without using your stomach or diaphragm.
Tongue Stretch (Finding the Pivot Point): Stick your tongue out as far as possible to feel the tension at the "root" of your tongue. This builds muscle memory so you know exactly which part to mobilize for the actual Frenzel.
Tongue Push (The True Frenzel): Rest the tip of your tongue lightly behind your upper teeth and relax. Now, mobilize the "root" of your tongue (that you just felt) and move it upwards. This will naturally push your tongue forward, pressurizing the air pocket in your mouth. The end result is similar to Step 2—the air goes into your ears. This is the true Frenzel technique you will use when diving!
III. Static Apnea (STA) Home Training Routine
Follow this cycle every time you practice breath-holding:
Body Scan: Close your eyes and move your attention from the top of your head down to your toes, like a scanner. Release any tension you feel (e.g., unfurrow your brow, drop your shoulders). Over a few natural breaths, consciously relax your face, shoulders, belly, and legs.
Inhale: Use the "Full Yoga Breath" you just practiced to take in a maximum breath. Relax your chest and belly, and lock the air in.
Breath Hold: Relax. Feeling the urge to breathe is completely normal, and the impulse will pass. The more you want to breathe, the more you must remind yourself to relax. Practice Positive Thinking: Do not focus on the act of holding your breath; imagine happy or relaxing scenarios to distract yourself. 🎉 Experiencing diaphragm contractions is great news! It means you are relaxed enough to feel them. When contractions arrive, do not fight or tighten your stomach muscles. Accept them, let them come, and let them go. (Note down the time of your first contraction and let your instructor know in class!)
Recovery Breathing: Once you finish the hold, immediately perform several quick, deep, and active recovery breaths. Ensure your mind is clear before moving to the next set.
📊 Part 3: Advanced Training - The O2 Table
⚠️ Friendly Reminder: You do not need to practice the O2 table before your first class. Just familiarize yourself with the equalization and breath-hold steps above. We will explain how to use the O2 table in detail during the yoga session.
Once you are comfortable with the basic breath-hold cycle, you can use an O2 Table to improve your body's tolerance to low oxygen. The goal is to tackle increasingly longer breath-holds while keeping a fixed 2-minute rest interval. (Note: The AIDA 2 Static Apnea requirement is 2 minutes).
Set | Rest Time | Breath Hold |
Set 1 | 2:00 | 0:45 |
Set 2 | 2:00 | 1:00 |
Set 3 | 2:00 | 1:15 |
Set 4 | 2:00 | 1:30 |
Set 5 | 2:00 | 1:45 |
