This gym seems to have some rather unfavorable reviews. In my experience though, it has been mostly positive. I went to the Ozone gym in the Zhongguancun area for 6 mos. Maybe the other locations are not as nice.

I thought this gym was pretty nice. Previously I went to a really cheap Hokay Chinese one, which I ended up quitting because it was just so bare-bones and hardly ever open. The area is huge, two floors, with the top floor for classes, plus a pool. It gets a little crowded on weeknights after work but usually I wouldn't wait more than 15 minutes or so for a treadmill. They also have a nice waiting area with tables where you can read, etc.

The locker room was decently sized and the showers were pretty clean (at least the women's), with a sauna that was much needed in the Beijing winters.

I do think it's probably a bit too expensive, and as a foreigner, I know they gave me a totally inflated price, but that's Beijing for you. I'm not sure about the trainers or the classes, as I didn't use either. Overall I was pretty satisfied with this place and would probably join it again.

I had a membership to this place from when it was Evolution Fitness and stuck with them through the handover.

Things were reasonable at the start, but things started going downhill after Evolution pulled out and Ozone took over.

To be fair, the two companies are about the same as far as level of service and management (so I'm not implying that Evolution - which is now defunct - is better than Ozone), but my experience here is all-too typical of many gym-goers in Beijing.

I prefer(red) swimming as my main workout routine - the pool here (35-meters, if I am not mistaken) is serviceable enough when it's not crowded. But up until I stopped going a few months back, it had become increasingly impossible to get in a decent swim with all the people in the pool, especially during lunch time when the big corporate membership crowds take over and basic swimming etiquette (i.e. sticking to one lane, not milling about in the middle) goes down the drain.

Then there was the extra RMB 500 "towel fee" I got rooked into paying when I last renewed my membership (over a year and a half ago, and before the change of owners) - it essentially turned out to be a ploy to squeeze extra money out of me at a time when Evolution was going out of business and it never sat right with me that I ended up paying extra for what eventually reverted back to a standard operating procedure after Ozone took over.

The next thing to go were the soap and shampoo in the showers, and throughout my membership here there has been a constant practice of "disinfecting" the shower room flip flops by throwing them in a large bucket of tepid, brown water, and I was constantly having to battle gym staff for the few remaining open lockers in the swimming pool locker room.

Many of the problems described above are typical of gyms in Beijing, and yes, I got a few extra months tacked onto my existing membership as recompense for the less-than-smooth ownership transition, but unfortunately Ozone's less-than-stellar management and the niggling skimping on materials have completely turned me off to this place - hence I let my membership run out without renewing.

ATTENTION ALL EXPAT'S!

Ozone is going out of business in 2009 Soho Club close down, and as of March 5 2010
Park Ave close it's doors, Wanjing and the Gate were transfer to other investors.

If you had sign up on a membership with Ozone there is a chanse that you might not get
your money back beacause their contracts are in Chinese and there is a clause that
states that you are not able get your money back if your membership exceed more that 7 days
or if you relocate,there might be a possible chanse that you can get your money if go to their corporate office located in Zhubang 2000 and talk to Howard Quach the founder of Ozone Fitness or Tomer Rothschild the CEO of Ozone Fitness several of members including my self got our money back but you have to be extreamly agressive with these characters.

Good Luck!
