I wanted to learn how to crawl. The course was well built. Very understandable and adapted to the needs of the student. The first successes came quickly.
I am very satisfied and looking forward to the next course

Hi Peter,

Thank you for the great course, highly recommended!
Not only have my swimming times improved, but also my “air supply” has increased considerably 🙂
Professional video analysis in particular has helped me to identify and correct errors. Now it's time to train, train, train ...

Hi Peter, thank you for the tips on my swimming technique. These helped me both i. R. d. Roth-Challenge to swim the 3.8km in a time of less than 71 minutes that was previously unimaginable for me as well as to keep the full power for cycling and running. VG Ulrich
