Can you complete the 4×4 Challenge?

Summer is coming to an end – what are you going to do with your spare time? We challenge students to complete our popular 4×4 Challenge in October – practice four times a week, for just four weeks, for 135€ in total (less than 9€ per class) and see just how easy it is to swap beach life and party time for strength, flexibility and inner peace. How many can you do?
