Kickboxing or similar in Berlin in April

Hi all - I'm coming to Berlin in April for a few weeks. I wanted to do kickboxing or something similar (i do a bit of muai thai), maybe every 2 days or so. Any ideas where I can do that?

Or are there any good sports that are easy to do - rockclimbing? or something else, not surfing, i guess....

someone recommended mma-berlin.de, which looks great, except the website doesn't work well and the email address is broken. so maybe they have closed? something similar anyone know of?

any ideas? thanks!

Which part of Berlin are you staying in? Many studios offer kickboxing and it would make sense to look for one nearby.

Rockclimbing: If you bring your own gear, there are some outdoor places (artificial rocks, though) where you can climb for free. I know of one place in Alveslebener Straße (Schöneberg). It depends on the weather of course, but in April, if we are lucky, it may already be warm.
These are places where you can climb indoors: www.t-hallberlin.de (in Neukölln), www.magicmountain.de (in Wedding).
