This tool revolutionizes swimming by giving instant feedback to the coach and fanatic swimmers. Insights are automatically displayed in real-time in the Swimtraxx coaching app. And as a swimmer, you can keep track of your workouts in a completely automated way. “It’s the little things that are vital. Little things make big things happen”, Olympic swimming champion Heemskerk shares, “The device is really small and will help me get more info on how I train,and on which details I can improve. It’s for that reason I became a Swimtraxx ambassador.”
