Munich Gym?

Hi my internations friends

I have moved to Munich last week and started my new job ...they pay for my gym membership but I'm finding it hard to pick a good one ...I'm living in theresienwiese and working in bohenhausen and I know, unless the Gym is on the way to work I won't go...
Does anyone have any recommendations for a good gym I'd really appreciate it

Regard.

Elaine
