    When are they gonna fix the bikes? Hard to stay in shape with broken bikes, and looking for droids is hard work.

    They have an entrance in the lower level of Potrero Center so parking is available. No need to worry about finding a spot next to the meters.

    Man I think they need to update the machines n they need to train the cleaning crew at night's. I was working on a cardio machine n the cleaning guy came n started to clean the machine. Strange.

    Free towel service for Super Sport members, even though this is Sport level.

    Locker rooms are DISGUSTING! Half the showers don't work. Watch where you step--someone is bringing razors into the whirlpool area. Gross!!

    Have yet to hear English but already heard 5 languages in the locker room. The most ethnic 24 hour fitness of them all

    Staff is super-helpful and there is a good diversity of resistance machines. Some of the equipment is a bit run-down but I mostly come just to swim so that doesn't bug me much.

    Re-racking your weights is appreciated.

    This gym needs to update the fitness area stationary bicycles because the current equipment consist of broken and missing pieces rusty and worn out bicycles.

    Be careful not to stretch and "block" emergency exits, Sean B. might threaten to call security on you if you don't move promptly.

    Les Mills BodyCombat coming to the Group X schedule starting April 6, 2013!

    The fact that they can't simply keep the paper towels stocked and the cleaning solution bottles filled reminds me why I don't like coming here.

    Q: How hard is it to keep a drinking fountain working?

    Look out for some girl doing the salsa on the treadmill!

    Try the sauna after a swim, it feels awesome!

    I'm amazed how they can't keep the water fountains working.

    Darren Riesz · November 14, 2012

    The gym needs to update the kids club with some fun stuff to do and need to update the hours.

    Been coming here for years, and it's so nice to see how hard working, dedicated people have transformed themselves :) Saw a few of them again today. Fucking Rockstars, seriously.

    One of the grossest 24-hours I've been to. Yet oh-so convenient. It's a conundrum.

    Paulette Bleam · September 18, 2012
  • Mike S.

    They keep changing the layout. And it keeps getting worse. Expect to bump into people while navigating the labyrinth upstairs.

    Just rename the pool, sauna and hot tub area to "elderly community center".

    If you manage to find an open machine, chances are it is broken.

    Hey, 24 hour! 1996 called and wants its decor back! While you're at it, how about improving ventilation/AC and maintaining the equipment better?

    Jennifer DeRuff · September 20, 2011
  • Jeff R.

    Nice gym, but the locker room is super humid and the cruisiest I've seen. Gives Van Ness a run for it's money.

    I can't say enough great things about the MWF 6am Spin Class with Christine. (I get there at 5am just to make sure I have a bike). The music and energy is great way to start of the day!
