In France we have Club Med Gym to work out, here in Sweden we could partake in the classes given by 'Friskis&Svettis'.
During sunny Summer evenings, this Club offers free training in a park close by. It looks like fun and is certainly sweaty to jump and move with music and with the instructor on the podium.......
But we prefer an early morning swim in the lake. No music necessary and the water is certainly 'frisk' in the sense of 'fresh, clean and cool'.
