“If you are looking for guidance on functional breathwork and to get properly started and more importantly stay motivated on implementing these practices into your daily life, I strongly recommend partnering up with Sylvia in her 100 day programme. Sylvia is competent, honest, knowledgeable, supportive and most importantly a good person who knows how to dig yourself up from a deep place. I Loved our sessions and saw what difference it made by being consistent over a period of 100 days. I got results and now I have myself new daily routines I stick to, which helps me on a daily basis. Thx coach 🙌” Mikkel Engstrom

“I have had the pleasure of working with Sylvia as my breathing coach, and I can honestly say that her guidance and expertise have had a huge impact on my life. Sylvia combines a deep understanding of breathing techniques with a warm, empathetic approach, which made me feel at ease from the very first moment.

Thanks to Sylvia’s coaching, I have not only significantly improved my breathing, but also gained a better understanding of how breathing affects my overall well-being. Her ability to explain complex concepts in an accessible and understandable way is truly impressive.

Sylvia’s dedication, her vast expertise and her sincere desire to help others make her an exceptional coach. I am incredibly grateful for the changes she has brought about in my life and would highly recommend her to anyone looking for an experienced and supportive breathing coach.“

“After my “Core Meltdown” I was saddled with a dearranged autonomic nervous system (unable to sleep, high levels of arousal and anxiety). This appeared to be the result of having lived a life ‘full throttle’ without a dedicated navigation system. With the professional help of Sylvia, a very friendly, critical, and empathetic coach, I progressively gained insight how to influence my autonomic nervous sytem with several breathing excercises. In that way I was able to turn down my overstretched system and reduce the annoying feelings of arousal and anxiety. Even more, it appeared to be a powerful tool to help me sleep again. Sylvia, many thanks for your help and giving me the right tools for getting my life back on track“

“The clear advice I received during the video consultations with Sylvia has helped me enormously to breathe better in my daily life. Now I just need to apply it during exercise. Sylvia knows how to convey her enthusiasm for her field very well. Thank you very much!“

“I used to struggle with knowing how to breathe properly and it used to make my anxiety so much worse. So I decided to give it a try and take some lessons with Sylvia and I was so happy with the results! She didn’t just teach me how to breathe the right way, but she also taught me all there is to know behind the science of breathing and it really helped understanding why I wasn’t breathing correctly and how good breathing is an amazing benefit. Whenever I get anxious now, I remember what I’ve learnt with Sylvia and I feel like I can really control it and calm myself down just by practicing breathing how she taught me. I would definitely recommend taking these lessons with her.“

“I met with Sylvia Keijzer randomly. When I learnt about her passion for breathwork training, i gave it a try. Honestly, it was a concept never known to me. I loved every piece of information i got from her. She herself has practice it a lot, have done scientific studies and knows very well how to teach others. The best part is the way Sylvia takes you to a journey of discovery “how breathwork can help” you being more calm, focus and most importantly control your emotions. Since then she helped me arranging her two sessions in my network. I just wanted to say big thanks for teaching me an impactful technique and wanted to wish her all the best. I am sure that you will touch many people like me with your wonderful skills to train them and help them to unleash their potential.“

“She is knowledgeable and dedicated. She guided in a beautiful journey to leadership by breathwork! I can only recommend Sylvia!“
