In London for a week - where to workout?

I am in London the last week of this month. I'm going to have time for a visit to the gym each day - any suggestions where I should go? Anywhere from: mixed gym where I can wear lcyra head to toe to: gay gym where I can wear really revealing gear, like a Tendenze tragerbody - or: somewhere to work out nude :) Suggestions guys? Phil

I'd love to find somewhere I can wear these in public :) http://www.xtube.com/watch.php?v=KoOJC-G607-#commentsContainer

A lot of guys at SohoGym Covent Garden wear lycra to work out, but Tendenze might be a little too much.

Understatement hardpecsbulge... wearing anything more revealing than Skins compression or its equivalent will have you thrown out of a gym in London and probably gets one done for public indecency. It is one thing to share the lycra fetish with like-minded people.. another thing to provoke controversy and unwanted attention.

So what about Sweatbox in Soho - what do people workout in there? I've heard the place is pretty filthy? Anyone go?
