Comeback Week 18 💦🤿 I'm going to the Philippines! 📝
-----------------------------------------------------------
Day 1 — rest day
Day 2 — Pool | 1 hr
Session - static
- Max Progressive 4:30
- Two-breath 5x 1:45
Notes
- notice how i do tables leading up to a number that is quite under my maximum
- that is the reason why i can do more than 1 table in a session, because i keep intensity moderated. If i would have done progressive 5:30 or 6:00 that would be enough for that day. I'd have to go home and sleep.
- two-breath 5x 1:45 was quite easy, allthough the water was getting cold and i was wearing my no-sleeve wetsuit. Next time for static in that pool i need to wear sleeves.

Day 7 — Pool | 1 hour
Session - DNF legs only
- few warm-ups
- multiple 25m laps legs only / limited recovery
Notes
- Working on the legs. Itr will take time and kilometers underwater to really dial in that technique. I can execute it, and my brain can command it, but to keep the technique consistent while combining with arm strokes and swimming lonhger distances underwater, that is still a challenge
- limited rest so we can consider this session as a CO2 training. No timer needed. Just feel and decide in the moment. You can always count your breaths in betweeen if you wanna have an idea of how much rest you have in between laps.
Pool technique is only one part of freediving performance.
Breathing, relaxation, and CO₂ control determine how well that technique holds up under pressure.

Today i had the opportunity to work with Oktagon MMA champion Kerim Engizek and medical & health coach Scott KetoDoc.
Great to see how high level athletes coming from other sports like MMA are showing interest in freediver breathwork! 💪💪
4:15 and 4:37 static apnea times for these two beasts! 🔥

Day 4 — Pool | 1 hr
Session - static
- 2:00 - 2:30 - 3:00 - 3:30 - 4:00 - 4:30
Notes
- worked online till midnight the night before, and didnt sleep enough. So i kept the session to moderate intensity.
- when you are training for a few months, it becomes very clear to hardest part is not the training itself, but the managing of your life in the best way possible. Like Muhammad Ali said - when they asked him about the hardest part of his training - he said: "it's being in bed by 9pm (and dodging the girls)".

Day 1 — Pool | 1 hr
Session - static
- Two-breath 5x 1:45
- One-breath 10x 1:00
- 1x 3:00
- 1x 3:30
Notes
- Went to the gym yesterday eve. So i already knew today's session would be difficult. And that's fine. It's a calculated decision. I just wanted to go to the gym, and i wanted to go to the pool 😂
- the one-breath 5x 1:45 as a start was too difficult. So i took a couple more breaths in between like 4 or 5.
- the one-breath 10x 1:00 was quite easy and i enjoyed it very much. Interesting to see how you can lift weights the night before and still enjoy static apnea the morning after. You just have to lower intensity.
- Finished of with 3:00 and 3:30 on mild HV, contractions started around 3:00 so i kept intensity very low.

Comeback Week 16 💦🤿 Thailand Heat vs. My Lungs 📝
-----------------------------------------------------------
Day 5 — Pool | 1hr + sauna
Session - static (tidal)
- no warm-up 3:30
- RV progressive 2:00
- Two-breath table 5x 1:45
Notes
- no warm-up feels like no warm-ups feel: it's just something you have to do 😆 (especially on tidal breathing)
- RV 2:00 felt quite confident and enjoyable, way better feelings than the no warm-up
- 5x 1:45 i stopped after the 4th hold. I decided it was enough. Yesterday did a long session and also gym in the evening. No need to overdo things just for the sake of completing a table. That would be stupid. Smart training means you start to develop that awareness that tells you when something is good enough and it's time to call it a day.
- With the heat of last week affecting my health i thought this week would be very low intensity training - if any training at all - but the week is turning out to be quite productive and strong!
- sauna + cold bath (3x)
- Peace 🙏

Notes
- Still not feeling 100% but apparently my low energy levels didn't really cause any problem today.
- The first few holds felt a bit weird, but starting from 3:30 i was getting in the zone
- Overall very nice session with confident and positive feelings
- On the last one i added 10 extra secs just for fun 😅
- I think i should do RV next session, just for variety.
