How to prepare for a Freediving course. (Swimming)

As the Freediving Instructor I was asked many times – do you need to be a professional swimmer to become a Freediver? And the answer is no, you don’t to be a pro. But there are no doubts that swimming helps a lot in learning Freediving, especially in the beginning.

So, if you are planning to do a Freediving course (find more information about Freediving courses) in the near future and want to be better prepared for it here are a few things which I recommend you to do in the pool

  1. Swimming with a mask and snorkel. Any style – breaststroke or freestyle – doesn’t matter. Benefits – you get used to breathing from a snorkel (and clean it from water), becoming comfortable with a mask and not stressed out when there is a bit of water inside
  2. Swimming with fins, mask and snorkel. Face down, not too fast, not too slow. Same benefits as above, plus you are working on kicking (not bending knees too much, correct rhythm etc.)
  3. Swimming with fins on the back. Improving the kicking technique and body position control. Make sure that your knee not coming up above the surface.
  4. Swimming with fins on both sides. Further improving your kicking style and body position control. Keep your body as horizontal as possible.
  5. Alternating swimming on one side, with swimming on your back. General body control.
  6. Vertical kicking (if your pool is deep enough). This style is close to what you are going to do in the open water

These exercises not going to make you an incredible Freediver, but they will boost your confidence in the water and improve your kicking technique. Here is a short video about the importance of swimming for a beginner Freediver.

How to train DYN for beginner Freedivers

In one of the last post, we discussed how you can train static (in case if you missed it, read here). And what about dynamic?

If for static you can do dry static apnea, then for dynamic you obviously need a pool.

Normally you can learn DYN on any PADI Freediving courses, but if you haven’t done any dynamic on your course, might be this video can help.

DYN Freediving training
DYN Freediving training

When you do static apnea – it is complete relaxation. The same principle can be applied for DYN – relaxation is the key. But in dynamic obviously you couldn’t relax all your muscles (since you need to move forward), but you should relax all the muscles not involved in this movement (neck, shoulders, etc). And even muscles which involved in the movement should be relaxed at the moment when you finish the kick (gliding phase).

Hopefully, it doesn’t sound too complicated.

How often do you need to train DYN? I think 2-3 times per week is enough for beginner Freediver. How intense? Not intense at all! Progress will come naturally.

There are few things about your technique, you want to be focused on. Choose one of them for a session and work only on it (let’s say be focused on your shoulders relaxation

Freediving technique

the whole session).

How do you know your mistakes? Ask your buddy to film you (GoPro does the excellent job)!

  • Head position (should be neutral)
  • Relaxation in the shoulder area (quite often too tense)
  • Buoyancy (the first thing which you have to fix!)
  • Kicking both directions
  • Start kicking from your hips
  • Not bending knees too much

And here a couple of examples of DYN training

  1. Main training – do short laps with 100% concentration on technique (mentioned above) and relaxation. If you current MAX less than 50-70 meters, do ONLY this training. Approximate distance 40-50% from your MAX. Amount of repetitions 5-10
  2. Easy classic CO2 training. Let’s say 25 meters with 30-60 seconds rest. 10 repetitions. A bit harder than the previous exercise.
  3. Over-under. Swim short distance (less than 40-50% MAX) underwater and without rest, swim same distance on the surface. Repeat 5-10 times. Can make it a bit harder if decrease surface distance.

Sorry to repeat one more time – focus on the technique and relaxation.

Do it for a month and then can try to increase your PB by 5-10 meters.

All the training should be done ONLY with another Freediver!!

How to prepare for a Freediving course

GH010152_Moment2121

Quite often future students ask, how they can prepare for freediving course, which they would like to start in a couple of weeks (or even months).

Of course, if you just heard that freediving exists and you want to try it immediately – just sign up for a course. During the course, the instructor will explain everything you need to know and help you to do all the requirements.

Check out which requirements you need to pass to become a PADI Freediver

But some people always prefer to be one step ahead and well prepared before they start something.

MVI_1849_Moment09For them, number 1 recommendation – spend some time in advance training your swimming skills. Yes, we have fitness requirements in PADI freediving course. But no worries, it is just basic swimming (200 meters without fins or 300 with fins) and can be performed in any style (also without time limit). If you know, that you cannot meet this requirement, then it is 100% better to train swimming skills before. In some organizations, though there are no requirements for swimming at all. Which seems extremely strange.

But even if you know that you are pretty good at swimming, it would be better if you go to the local pool, or even better the sea, to practice. Because more time future freedivers spend in water before the course, the more confidence they gain. Thus in such simple cases as leaking mask or water coming into snorkel students feel less stress. The whole course will be more smooth and you may feel more relaxed if such small details will not disturb you. So the 1st thing you can do before freediving course – remove stress by regular swimming (with fins even better).

The next thing which we recommend to work on is  Frenzel equalization. If you tried scuba or freediving before, you know how and why to equalize. If you are looking for some explanation on how to work on equalization, check this youtube video. Besides, let me know in comments if you have some questions about it.

Indeed equalization in freediving is probably the key point. Even scuba instructors sometimes are facing challenges with Frenzel equalization, because diving head first in vertical position differs a lot from diving feet first. In this concern, it would be useful to spend some time practicing it in advance.

MVI_0481_MomentWhat else can be done if you have a few months ahead before the freediving course? You can do some stretching exercises. Stretching is beneficial for freediving, however, it is easy to pass the 1st level without any stretching at all. But if you are going to do advanced or master course, stretching will be super valuable and will help to make the course much safer and enjoyable.

The 4th thing on which it is better to focus is relaxation breathing. There are plenty ofMVI_0500_Moment mald breathing technics for different purposes. You need to focus on relaxation breathing for freediving (here is the link on basic relaxation breathing routine).

Also, so many people ask what they can read before starting freediving. My answer is always the same – just read a freediving manual. I don’t know about other organizations but in PADI we can provide students with the freediving manual in advance, where you can find theoretical aspects and practical advice.

I hope this information was useful.

And if you have further questions, or maybe, want me to cover some precise topics in next articles – feel free to let me know in comments.

How to start training STA breath hold

First Freediving course is over (if you haven’t done it yet – check here for more details), you are happy and willing to train more to become a better Freediver. The big question – how to train?

If you are lucky, and there is a Freediving club nearby – then just join it. You will find support and motivation there. But what to do if there is no Freediving club nearby? How to progress? Well, this is what we are going to discuss here

IMG_0511First of all – if you are planning to train in the water, you HAVE TO have a Freediving buddy. No exception. What about easy breath holds? Still no, you have to have a buddy in any case! If no – train STA dry (less fun, but safer!).

Before you start – refresh your knowledge about Breathing process in general (at least a part that it is CO2 which caused the desire to breathe, not O2). Don’t know where? Check out our video about it here

The worse what you can do in the beginning – is to start pushing your limits too hard! Why does it? Impressed someone? Because your friend can hold breathe longer? Or is it because 3 minutes sound impressive? Whatever reason you have – don’t do it.

Remember, a huge part of Freediving is relaxation, so, start with it.

But let’s be more specific. Let’s say your breath hold on the course was about 2 minutes. IMG_1180And you want to reach 3 minutes within 3-4 months. Here is your plan (train 2-3 times per week). Choose only one of these exercises for a session

  1. Do 5-7 breath holds, without checking the time at all. Finish every attempt as soon as you feel uncomfortable (urge to breath). Your goal is relaxed breath holds
  2. Do 5-7 breath holds, with start timing only after you start feeling uncomfortable. For example, your safety buddy can count to 10 (or less) after you have your first contraction. The goal is still to stay relaxed even after you have an urge to breathe.
  3. Do easy CO2 tables (more details in the video here). Increase your breath hold time very gradually (only last 1-2 breath holds should be challengeable). The goal is slowly to accumulate CO2 and still be relaxed
  4. Practice relaxation breathing (as meditation, pranayama breathing, and three section breathing). The goal is not to fall asleep.

IMG_1313Have you noticed “PUSH HARDER” advice? No? This is because there is no such advice here! You don’t have to push harder to reach 3 minutes static breath hold!

Stay safe and progress slowly!

 

How to choose a mask for Freediving

Probably the 1st thing your personal freediving equipment starts with is a mask and a snorkel.

freediving maskThis step is easy to explain: rental masks might not fit you well and can constantly leak. Besides, it’s always more pleasant to be the only one who wears the mask which touches your face. Also, you don’t depend on rental shops operation hours and with your own mask, you can go snorkeling or freediving wherever and whenever you want. And the last reason – it’s super easy to travel with a little mask in a bag. Way easier, than with a pair of freediving fins.

So how to pick up the decent mask? If you are already a certified Freediver, probably you know the answer. If not, let me explain

Remember one thing – the best mask for you is the mask, which fits you independently on cost and brand.

Let me give you a couple of advice on how to pick up the perfect mask.

It is always better to try the mask first. Ideally in the water, but at least in a shop.

And there are two main things you ’d better pay attention to mask shouldn’t hurt you and you should be able to equalize in it.

If you put the mask on your face and press on the top of the nose bridge and if you feelDCIM101GOPROG0091796.JPG little pain, this mask is not for you. As little pain can become a terrible headache after 1-hour freediving or snorkeling session.

Another important thing – equalization. Be sure that you can pinch your nose to equalize. Some masks have extremely huge nose pocket, like Omer Zero, and it’s a real challenge to find the nose in such a mask.

Let’s talk about the features, which mask should have to be suitable for freediving.

So, in freediving unlike to scuba diving to equalize the mask we are using our air from the lungs, which is limited and which we actually need to dive deeper. That is why for freediving mask it is extremely important to be as low in volume as possible. And single lens mask has always more volume then double lens one. In this concern, you need to look for a double lens mask. Soft silicone skirt is important as it seals better around the face. And except that it is much easier to pinch the nose for equalization. In this concern, PVC skirt masks are not a smart choice at all.

Let’s take a look at one example of the mask.

mask for freedivingYou might have seen many freedivers diving in Sphera mask by Aqualung. It’s a gorgeous not expensive and unique mask due to its bent lenses, which allows the mask to follow the shape of the face. This provides super low volume and high side vision. But to make the lenses curve manufacturer had to use plastic instead of glass. And plastic is much less resistant to the scratches. That is not a problem at all if you care your equipment well. In case, you have a habit to drop your mask anywhere but not in the box, probably you have to check for another option.

And the last thing which I would like to cover is the difference between brand and noname masks. Brands usually provide good warranty conditions and in case your mask is broken due to manufacturing failure, you can apply for warranty repair or replacement. But be sure you have saved the receipt to confirm your purchase. The best way is to take photos of all your receipts and keep the digital copies in case you lose a paper bill.

I hope all these tips will be useful for you when you come to the shop for your 1st Freediving mask.

And if you have any questions, please don’t hesitate to ask in comments below.

Freediving vs Scuba Diving

DCIM100GOPROFreediving, as a recreational water-based activity (as well as a sport), getting more and more popular. But still, it is far away from other water activities, like for example scuba diving.

There are a lot of myths around Freediving, which stopping people to try it. Or at least confusing.

Let’s try to find out which one is true and which one is not. So, let’s start!

  1. Freedivers can come much closer to the marine life. NOT TRUE. Well, actually it depends. If you compare an experienced Freediver and a beginner level Scuba Diver, then it is true 100%. But if we compare both an experience Scuba Diver and a Freediver, then it is not that simple. As a former scuba instructor, I had a few thousands of dives and I can say that majority of the marine life can come very close to you (reef fish, turtles, stingrays, sharks etc). Less than a half meter. SomeDCIM101GOPROG0154199.JPG people are saying that fish afraid of the bubbles. But why should they be? Fish are afraid of their natural predators and they don’t make bubbles. Fish afraid if you make too much movement and if you are rapidly closing the distance. However, I am willing to accept that some marine life can come close to a Freediver (at least I was told so by other Freedivers).
  2. Freediving is more environments friendly. TRUE. Freediving boat is usually much smaller and requires a smaller engine. And they don’t have compressors. It reduces air and water pollution (as well as noise pollution). All of this makes a difference on our impact on Nature. Also, Freedivers are usually not that close to the corals (especially beginner level), so, fewer chances to damage fragile corals. We are also diving on the reefs less often (mainly we are diving just in the blue).
  3. Freedivers have less equipment. ALMOST TRUE. If you compare Freediving vs Scuba Diving – you will probably think – oh, this is 100% true, but it is not that DCIM102GOPROGOPR3616.JPGsimple again. If we are talking about starting – then for sure it is true! As soon as you have a mask, you can be a Freediver 😉 For scuba, even for absolute beginner level, there is a standard set – BCD, regulator, fins, scuba tank etc. Coming back to Freediving, like I said, in the beginning, you can just invest in the mask and snorkel. But then it will probably be more equipment – weight belt, neck weight, wetsuit, nose clip, safety lanyard, goggles for the swimming pool, float and rope if you want to train with your buddy independently, etc.
  4. Freedivers are leading a healthier lifestyle. TRUE. Some people like to call Scuba Diving sport, which always confuses me. Obviously, it is not. But freediving is. Even if you are not very serious about results. Freediving training combines correct breathing, different relaxation techniques, different physical exercises (in open water, pool, gym etc), as well as mental training. So, yes, if you like to be connected with Nature and stay healthy – Freediving should be your choice.
  5. Freediving is more dangerous. ABSOLUTELY NOT TRUE. Let’s make a line between Freedivers who are properly educated and follow safety rules and someone who has no idea about basic safety rules and just decided that he/she needs to dive deeper or hold the breath longer. Among the first groups, some problems occur, butDCIM100GOPROG0010673. they are not fatal. The second group is just playing Russian roulette. But the same is true for any other activity in our life – you have to follow safety rules. Even for walking. Disagree? Try to walk across a high way! When someone tells that Freedivers are dying regularly, I am always asking where this information is coming from. And there is no answer. Simple because it is not true. So, the bottom line here – follow safety rules and Freediving would be the safest water based activity!
  6. Freediving is a more natural way to be underwater. Well, of course, it is TRUE. We don’t create with the scuba tanks on our back. But we have reflexes which help us to stay underwater longer and dive deeper. Holding the breath for a certain time is natural for us, as well to the other marine mammals.

 

DCIM104GOPROG0549191.So, what would be your choice? Ideally, try both freediving and scuba diving! In my opinion, if you want to explore reef up to 15 meters deep – Freediving is a much better choice. But if you are planning to explore a dive site 25-30 meter deep, then it is easy to do with a scuba tank. If you are interested in underwater photography or videography, then again, having scuba tanks make your life easier. On the other hand, if you want to enjoy to be underwater and also combine it with a healthy lifestyle – Freediving is a better choice.

Freediving problems. Part 1 (LMC/BO/SWB)

I usually ask my students, what do they think, is Freediving dangerous sport or not? And

Freediver in the pool

if it is a PADI Freediver course (first level in Freediving), more likely the answer is yes.

What do you think about it? Stop reading for a second and let me know your opinion in the comments section at the end of this article!

Done? Good!

Ok, let’s start with it – any activity is potentially dangerous. And I am not even talking about such activities as a base jumping or rock climbing. Walking on the busy street can be extremely dangerous, right?

However, if you follow the rules of this particular activity – risks can be dramatically minimized (don’t walk on a highway for example). And Freediving is not an exception. Follow simple safety rules and Freediving would be the safest water based activity!

But I would lie to you by saying that there are no risks in Freediving. Are they big? Let’s have a look.

It is going to be two parts about most common problems in Freediving.

First one about – LMC/BO/SWB

IMG_0511And second is going to be about lung squeeze, DCS/lung overexpansion/gas narcosis

 

Before we start – it is very unlikely that you are going to experience it on your Freediving course (especially on the first level – chances close to zero). But with the experience, you are going to be not that much distracted with a high level of CO2 (you still have contractions, but you are going to be more ok with them) and able to hold your breath longer and longer. And longer your breath hold is, less O2 it is going to be at the end of it. And less O2 you have more likely problems can happen.

Let’s say a Freediver decide to do his PB (personal best attempt). He is relaxed and enjoys his breath hold. At some point, contractions (involuntary movement of respiration muscles) will start. But he is still relaxed. He has them before and he is not freaked out, everything is under control. Contractions become harder and harder, but he is still holding his breath. At some moment, contractions became unbearable and Freediver comes up. But because the level of O2 reached the critical level, there is a chance of LMC (loss of motor control). What happens with this Freediver if he has an LMC?

20180201_074458He is still conscious; the heart is working, blood still circulating through the body. But the partial pressure of O2 is too low for normal functioning. He is not fainting, but close to it. Signs can be small (blue lips, light uncontrolled eyes or head movement), or big (body shaking and losing coordination). What happens when a freediver lose coordination while he is in the pool? Big problem…

And this is why your buddy is very important! Safety buddy is going to grab the Freediver, provide support, remove a mask from the face (or nose clip) and encourage him to breathe!

 

HOW TO AVOID LMC?

  1. No hyperventilation before any breath hold
  2. Don’t push too much (be moderate with your progress and don’t do big jumps in it)
  3. Secure support (float, pool’s edge, your buddy arm) after surfacing
  4. Proper recover breathing after stop holding.
  5. Don’t do PB’s if you are dehydrated, too tired, you haven’t slept well, it is your second training per day etc

AND NEVER FREEDIVE ALONE!

HOW TO DEAL WITH LMC?

  1. Support your buddy, making sure airways about the surface
  2. Remove mask/nose clip
  3. Encourage to do recovery breathing
  4. Be ready to deal with BO

DJI_0760_MomentIf you have an LMC, take it as a lesson, stop training for at least a day, analyze why it happened and don’t repeat the same mistake 😉

 

What is BO? In Freediving we call it a situation when Freediver lost his conscious due to hypoxia (insufficient supply of O2) during the long breath hold. There is a difference between hypoxia and anoxia – complete deprivation of O2 supply. Why it is important to understand this difference?

Anoxia is extremely dangerous because some of our tissues could not survive without O2 supply even a couple of minutes (brain as an example). During hypoxia there is still available O2, but not enough for normal body function. And the protective mechanism launched – Freediver experience blackout.

 

HOW TO AVOID BO?

  1. Don’t do hyperventilation
  2. Do recovery breathing after any breath hold
  3. Avoid pushing too much your limits (especially if you are a beginner)
  4. Don’t depend on the watch, if you feel that you need to stop – stop!
  5. Have enough time to recover between Freediving sessions
  6. Don’t train when you dehydrated

AND NEVER FREEDIVE ALONE!

 

HOW TO DEAL WITH BO?

  1. Learn rescue skills under professional supervision
  2. Practice these skills
  3. If your buddy has a BO – don’t panic, you can easily recover himDCIM100GOPROG0030109.JPG
  4. If you have a BO – stop your training for today
  5. If there is a chance that you inhale water – look for a medical checkup

 

As you know, BO happens when there is not enough O2 for normal buddy’s function (when a partial pressure of O2 below a certain level).

When we are diving, pressure changes very fast, compared to the surface. When we are only 10 meters deep, pressure increase twice (2 atm), 20 meters – three-time (3 atm) and so on. Same happens with the pressure of any gases in your body, include O2.

Deeper you go higher partial pressure of O2 you have.

But now you turned 😉 And while you are ascending, you are still burning down O2, but now also pressure decreasing. And on the last 10 meters, it is going down twice. And this is where the majority of SWB happens (some of them even on the surface).

 

swb2It is almost the same recommendations which I wrote about how to avoid BO! let’s repeat

  1. Don’t do hyperventilation
  2. Do recovery breathing after any breath hold
  3. Avoid pushing too much your limits (especially if you are a beginner), in case of SWB – don’t progress with depth too fast
  4. Don’t depend on the watch/depth, if you feel that you need to turn – turn!
  5. Have enough time to recover between Freedives (apply the rule, surface interval 3-4 longer then dive time or more conservative time)
  6. Limit the number of deep dives per session
  7. Don’t train when you dehydrated

AND AGAIN – NEVER FREEDIVE ALONE!

 

What to do if your buddy has SWB

  1. Reach the diver
  2. Grab him
  3. Bring to the surface
  4. Remove the weight belt if necessary
  5. Blow-tap-talk for 10 seconds
  6. 2 rescue breath and ask for help
  7. Start moving the diver to the boat/shore, providing 1 rescue breath every 5 seconds
  8. Remove from the water and start CPR

Everything that you need to know about MDR (Mammalian Dive Reflex) in Freediving

First of all the term, Mammalian Dive Reflex is a little bit misleading term since not only mammals have it. So, let’s call it Dive Reflex or Dive Response or just DR 😉

Doesn’t matter, you are complete beginners or you already Freediving Instructor, Dive Reflex is your best friend!

A bit of history. Many years ago one French doctor made a statement that man could not dive deeper than 50 meters because the thoracic cavity is going to be crushed (some sources say 30-40 meters). Why? Because every 10 meters pressure increasing with 1 atm and when you are 50 meters surrounding pressure already 6 atm. And it is huge. But back to those time, no one was even trying to do it (ok, there a couple of exceptions). But in 1961 Enzo Maiorca dived to this depth and survive! Why? Because of the blood shift! And blood shift is a part of DR!

DCIM102GOPROGOPR1302.JPGDR is activated when our face is cooled (by cold water for example) or when we hold our breath. When we do both – even better!

This reflex helps us to hold our breath longer and dive deeper! How? By:

  1. Apnea
  2. Bradycardia
  3. Peripheral vasoconstriction and blood shift
  4. Spleen contraction

1. DR is responsible for spontaneous activation of Apnea. If we place infant underwater (don’t ask me why) their windpipe would spontaneously close (by vocal cords) and this prevents water from entering the lungs. This reflex quite strong upon 6 months and then start to disappear. My assumption – around this age baby start learning how to crawl and probably decide that Dive Reflex is not that important for them! Does it happen because of our genetic memories of our aquatic past or because nine months before birth our natural environment is liquid? Who knows 😉

2. DR causing bradycardia – slowing your heart rate (HR). Quite common is 10-30 % DCIM102GOPROGOPR0029.JPGreduction of HR for Freedivers (up to 50% or more in highly trained athletes). There are stories with even more impressive results, but let’s skip them now. Sounds impressive? How about this – laboratory rats have 80% decreases in HR while submerged underwater!!

Bradycardia is usually followed by tachycardia (increase in HR) after breath hold is over.

Why bradycardia is important for Freediver? Well, it is a protective mechanism of our body, it decreases O2 consumption, which means we can hold our breath hold longer without risk of losing the conscious! It also compensates the result of peripheral vasoconstriction effect (which cause increased blood pressure)

3. Next benefit of DR is a peripheral vasoconstriction and blood shift

Back to 1974 study showed that during dives to 40-60 meters, the amount of blood in the thorax (chest cavity) increased more than twice! And this reflex was called (pretty obviously) blood shift.

DCIM102GOPROG0053175.JPGPeripheral vasoconstriction (PV) is a narrowing of the blood vessels to reduce blood flow to non-vital organs (such as skin or inactive muscles, for example) ensuring that oxygen-sensitive organs like the brain or heart receive enough O2 for normal function. In another word PV is a redistribution of blood to vital organs from peripheral organs. PV also induces anaerobic metabolism, with an increase in lactic acid as a by-product. Interesting that the release of lactic acid into the bloodstream doesn’t occur (or at least significantly reduced) until Freediver resurface (at least this is what experiments on laboratory rats show).

For all of the above, you can say that blood shift (BS) happens (blood moves from non-vital organs to vital organs) when PV happens, but quite common Freedivers are using the term BS when describing the movement of the blood to the chest cavity to protect it from increasing pressure while diving deep.

Due to PV certain amount of blood pushed to the lungs, the capillaries in the lungs receive a greater blood flow and increase in size, compensating for space lost in the lungs due to increasing of ambient pressure. The lungs become filled up with the blood, which is reabsorbed when Freediver ascending.

IMPORTANT! Blood shift not pushing the blood into alveoli! It pushes it into capillaries around alveoli!

Why PV is very important for Freedivers? Well, it helps to move O2 from organs which can survive longer without it, to organs which are in constant demand of O2. So, it helps us to hold our breath longer and dive deeper (by moving blood to the chest cavity).

4. And the last but not least benefit of DR is the spleen contraction. Spleen in the human body has two main functions – mechanical filtration of red blood cells (RBC) and as a part of the immune system. We are interested in the first function. About 240 ml of RBC’s can be held in the spleen and released when needed (due to hypoxia for example). When the contraction of the spleen happens oxygen-rich RBC’s gradually start their journey to circulatory system increasing O2 carry capacity of our blood (and helping us to hold our breath longer).

Interesting that spleen not recovering fast, even after an hour it is only partially recovered (however there are studies which show that spleen can be fully recovered in size in less than 20 minutes).

5. This is not a benefit, but still part of DR. Immersion diuresis. Yes, this is an explanation DCIM102GOPROG0022614.JPGwhy while Freediving you want to pee much often! As you know part of DR is PV and it causes increased blood flow to the torso area and increased blood pressure as a result. Our body detects it and releases a specific hormone responsible for liquid regulations, which increase urine production. Don’t be embarrassed because of it! But make sure that this reflex doesn’t make you dyhadrated (drink enough before and after Freediving session).

6. Another side effect of DR is faster muscles fatigue. And again you can blame PV. When PV happens and blood moves away from your muscles, they start to work in an anaerobic way and produce more lactic. And even after you finish apnea, the effect does not disappear quickly (depends how long and intense your apnea was). Do you need proof? Try to do DYN bi fins 100 meters and 100 meters surface swim (with the same fins) and compare how do you feel.

How to hold your breath

The basic skill which you learn on your first Freediving course is, of course, how to hold your breath! This Freediving discipline requires a minimum of Freediving equipment!!

A lot of my students, when I ask them, how long they can do it, answering – 30-40 seconds. And then in 10 minutes, they can hold for 1.5-2 minutes! Magic? Not really 😉 Simply understanding how to do it correctly, what happens in the organism during static breath hold – helps that much!

Watch how our student does it for the first time! Interesting to try? Come to Koh Tao (Thailand) and we going to be more than happy do Freediving course with you!

Equalization for Freediving

Hey guys!

Common question: If I am planning to do Freediving course soon, do I need to somehow prepare for it?

Answer – YES

😉

And one of the thing which you can learn even before you sign up for your first Freediving course is how to equalize your ears!

It will rise chances that you will pass this course without any problem

How to learn it? Watch the tutorial on my YouTube channel (and a few videos how to sorted out equalization problem, if you have them)
