I will probably be spending some time in Muenich, Germany, due to business I have to attend to. I will probably stay there for two weeks at a time and certainly don’t plan to stop working out while I am away. I know my area will be somewhere between Grosshadern and
Graefelfing, and around Goetheplatz and Sendlinger Tor. Anybody knows about gyms there? How much do they charge for 4 sessions/week and can I pay for every week, separate sessions or just monthly? Danke schoen,sehr geehrter Herrn. 
I have no idea about gyms, but Munich happens to have the best club I’ve ever seen! It’s called P-1, and, if you want to spend an evening surrounded by the most beautiful people ever collected in one place, I recommend you check it out. I believe it’s close to Marienplatz, but I could be completely off, as it’s been several years since I was there and the night has always been a bit hazy… I do know it’s located behind an (art) musuem. Enjoy.
