The main skills of the SSI Level 2 is the Free fall. The technique Freedivers use to effortlessly descend at greater depths. It is like flying underwater. At depth, Archimedes’ law leaves place to Boyle’s law. As our lungs and wetsuit compress by the depth of the water, we start falling in the ocean. It usually happens between 15 and 20 metres, but with efficient breath ups, this becomes not only comfortable but also useful skill, enabling us to go deeper. During free fall, being completely streamline is important; we need to be hydrodynamic to fall quickly. The key to this is complete relaxation of mind and body to be able to experience the peaceful descend. Just like all aspects of freediving, posture is critical to success during freefall. If you bent backwards or forwards, you are no longer streamlined and will not freefall effectively. Freefalling is describe, as the most beautiful thing there is in Freediving, do not miss it!

Frenzel equalisation: 

The Frenzel technique is the primary form of equalisation. It is the most efficient and the most powerful technique available and it allows us to go deep with a small amount of effort. The technique is very simple once you have it mastered, as it will become completely natural to perform. In very simple terms, it is all about compressing the airspace held between your Glottis and your lips/nose. By only compressing this area, we minimise the amount of air needed for equalisation thereby leaving more air to achieve greater depths. All you are doing is compressing the air in the mouth to push it in to the airspaces of the head, do not over think it. Use every facial muscle in your arsenal and make sure you are relax. Your instructor will demonstrate this equalization skill and give you exercise to make your Frenzel stronger. This equalization technique can do use while scuba diving always, it allow more relaxation, less risk of ears injuries and a better O2 conception.

Full and empty Lung advanced stretching:

Ever since the days of Jacques Mayol, top level freedivers have recognised that the right kind of stretching is critical for optimum freediving performance. You will be hard pushed now to find anyone in the top flight for any country who does not have a regular yoga practise, lung or sport-stretching routine. These stretches isolate specific muscle groups and help to prepare your body for physical exercise, as well as developing flexibility over time. Studies show that stretching before any kind of physical exertion helps to improve your performance and reduce injury if done correctly. Lung stretches help a freediver’s body to handle the pressure at depth and, over time, will allow us to take a better lungful of air. Exercises focus on reducing Residual Volume (RV) and increasing Total Lung Capacity (TLC), which effectively means that the lungs can reach a smaller size whilst still providing air for equalization. Many of the exercises originate from Pranayama and Kundalini forms of yoga. Yogis use those techniques for millennia to improve their overall health and wellbeing. The average size of the human lung is 4-6L, some of the best Freedivers can reach up to 15L lung capacity which is very useless for deeper and longer dives.

Static Apnea:

We will introduce new training techniques in the shallow water to improve your breath hold. These include Apnea walking and Co2 O2 tables. Not only is it good fun but these practices help you dive deeper and improve your confidence in the water. Freediving training tables are a series of dives mostly done during static apnea, that push our tolerances and condition our bodies to deal with either high co2 or low o2. A co2 table is basically a series of dives which gives you less and less time to recover in between breath-holds. So the co2 in your blood and tissues slowly creeps up and up throughout the exercise. You and your instructor will slowly increase your tolerance to Co2 and you will be soon able to hold your breath for 4 minutes ! o2 tables are designed to increase you maximum breath-hold, by increasing the amount of time that you retain you breath for on each attempt. The recovery phase is fixed, unlike the co2 table, so the co2 is expelled properly in between dives. These kind of tables are important to get the body working well under the effects of low o2. Our French instructor Florian Dagoury is able to hold his breath for 9 minutes in static apnea, you are in good hands!

Freediving Dynamic Apnea:

The best way to become a better freediver is of course to train freediving. As a beginner, the more time you spend in the water the better you will become. But eventually you will reach a plateau, where one of several things can stop you from getting further. Training pool disciplines such as Dynamic with and without fins will bring your Freediving skills one step further. Your instructor will focus on refining your technique and challenge you to become more comfortable swimming while holding your breath. You will find yourself surprised by how this feels and build confidence for depth training. Every sport forms in athlete a certain kind of morpho-functional harmony. Dynamic training methods must take into account functions and properties of neuromuscular apparatus working under situation of breath holding. When you Freedive, energy supply of organism occurs at the background of rapidly increasing oxygen deficiency. At the same time, compensatory activation of anaerobic glycolysis (energy production without oxygen utilization) raises lactic acid concentration in tissues up to the toxic level. Freediving is a complex activity. It combines many types of muscular and energy systems, as well as integrating the body-mind connection, so your training should include all of these. The big tricky part is WHEN and HOW to train WHAT !

Depth in Constant weight and Free Immersion:

Dive down to 20-30 meters. Improve finning technique, learn multiple new techniques that teach you to hold your breath longer, proper buoyancy, and how to ‘’free fall’. A process that will help you descend deeper with less effort. What most people do wrong is that they train the same thing in the same way for a long time – and then wonder why they don’t get any results anymore. What happens during training is that your body adapt to the type of training you expose it to, and eventually it’s fully adapted and you don’t get any stronger, faster, better Freediver. During this open water session your instructor will give many different exercices to increase your depth without you feeling any sort of stress and in no time you will notice than 20 or 30meters dives feel exactly the same. Soft, smooth, quiet, confident, serene, peaceful: all these adjectives hint at the intense pleasure well-trained freedivers feel !

Fun Dive and Pictures:

At this point in our adventure, we will take you to Koh Tao’s most beautiful diving locations. Here we will use all the skills we have learnt, including the buddy system, to explore the ocean freely. Some of our sights include hidden underwater statues, swimmable caves, coral reefs, and colourful schools of fish! As a part of our package, we offer you an underwater photo of yourself! We have an underwater photographer on our team, ready to take your picture! Say cheese, or stay in action and let us capture the moment! We will send these photos to you promptly via email.
