"I have been participating in AIDA freediving competitions since 2011. Constant Weight No-Fins was the discipline I most neglected – it just seemed too technical for someone without a swimming background, and too difficult to train in our freezing lake. But Stefano’s training program combines pool and dry training, integrating strength, endurance, mobility, technique – and joy: While previously the motto was “no pain, no gain” (I actually liked having someone shout at me, maybe because I am German), Stefano has taught me to focus on the joy of feeling the water and smooth body movements. Thus, I finally came to embrace the wonderful discipline of CNF. Thank you for your expert coaching, Stefano, and thank you, Stefano and Sun Young, for being such lovely people!"
