Emine Aydemir is a devout Muslim woman,living in Cologne. She runs a fitness studio for Muslim women – no men are allowed. The women can train with or without a veil. There are no men around so their husbands generally have no objections to them going there.It’s a welcome change of pace from domestic life and many say it’s helped boost their confidence. But Aydemir says she doesn’t want to run a ghetto: courses are given in German and women can attend whether they are Muslims or not.
