hello Bernk welcome in advance...been living in Bern for the last 2 years....there are lots of "fitness" opportunities here in bern....to start with in spring and summer one can go swimming in the Aare although the water is still too cold for my taste...one can go jogging along the Aare, biking and hiking in Gurten...you will find gyms everywhere...so theres no problem there....hmmm....an in door pool is what is lacking...
I know one can swim in the university pool but I don't know if its open to the public....
