Gert has completely changed the way I look at static apnea. It used to be the part of freediving I enjoyed the least, and I honestly had quite a negative mindset around it. Now I’m actually curious about it and looking forward to my static sessions! 🤯 What I really love about Gert’s approach is that not every exercise has to be hard or exhausting. There’s so much variety in the way we train, and that makes the sessions feel interesting rather than another thing you just have to suffer!

I just love being part of this community. Have been it for a long, long time. I love all the live streaming, all the videos, the way that it makes me calm, more relaxed, sleep better, get more into the zone. I do this for health reasons and for zen reasons. And I feel so safe guided by Gert, who is an awesome man with the best skills and values that really resonate with me. I can't recommend this enough. Just do it. Get inside and feel better right away.

A huge thank you to Gert! He is always very attentive and answers our questions with great precision. Even when I don’t have time to train, I can always learn something here about freediving, mindset, techniques or physiology. I now train in different places with qualified people, but Gert is still one of the most precise and present coaches I know. And hello to the whole Squad — you’re amazing! 💙🌊

I have been training with Gert since 2023. When I first started, my breath hold was 2:00 min. When the Underwater Squad was developed, I immediately joined and worked through the 6-week challenge. I went from an untrained 2:00 min static apnea to 3:46 min with understanding. I love the program! I am continuing to grow my understanding of apnea as well as freediving through the Underwater Classroom. New lessons are being added regularly. Gert is an amazing coach! The community is supportive <3

What I love most about this community is that you find everything you need in one place, from the basics to advanced training. The 6-week Basic Program builds a solid foundation, while Ultimate2 helps you progress further. Gert’s live sessions and feedback are a great bonus. But most of all, I love seeing other members improve — their progress and positive feedback are incredibly motivating. A truly supportive community has grown here over the years!
