    It's a clean facility and the check-in attendants are extremely nice, but the layout is terrible and classes fill up really fast

    I go there because of proximity ti my job, but it's small and the women's bathroom stalls are always dirty

    The men's showers are moldtastic. If you have a shower at work you should use that instead.

    Sierra Kellogg the best trainer! You leave feeling about 10x more fit than when you got there!

    Unless you like the dance remix of a bad cover of Bon Jovi's "Living on a Prayer" by a former country singer I suggest you bring your own music. #owmyears #hashtagsonfoursquatr

    Gets packed around lunch time and b/w 5-7pm. But at least there's eye candy for motivation! 

  • Jacob G.

    It may be clean, but their cardio equipment constantly breaks down...not the must proactive when it comes to club maintenance

    Jacob Green · December 15, 2011
  • Anthony N.

    One of the better 24hr fitnesses in the city. Come here after 7pm when it's not busy so you don't have to wait for equipment.

    Anthony Nudo · December 1, 2011
  • merredith l.

    The finger scanner at this location is bad. Be prepared to have a hassle bout it not working right 8 times out of 10.

    merredith lloyd · October 1, 2011
  • Ceej

    Got rid if one if their custom made for the space power cages and put in more pull press bowflex crap. SUCKS!!!

    So clean & quiet. Skip from 4:30-6ish pm during the week if you can it's packed. But still a great vibe if you can't. Best 24hr I've been to. Personal trainer Michael Friedman is fab & enthusiastic.

    Meighan O'Toole · April 28, 2011

    The ladies bathrooms stink like nothing else here Yuk. Otherwise, good gym!

    This facility is superior in the network. Clean, neat, nice and all the features - minus the swimming pool.

    Tamas Kalman · December 17, 2010

    Yoga on Wed at 1PM with Summer is great.

    Adam Carey · October 8, 2010
  • Chris G.

    Also, try Sgt. E's Pilates class on Tuesdays & Thursdays from 1 to 2pm. Excellent workout for mind AND body.

    Chris Gehring · June 14, 2010
  • Chris G.

    One of the best 24HR Fitness Gyms in the City. Equipment is new, atmosphere is nice (on the quieter side), classes are good.

    Chris Gehring · June 10, 2010
  • Ariela

    You can get 24 day free trial as the max. amount. Use it wisely. Come in the morning when all of the machines are available.

    Ariela · April 30, 2010
  • Alex H.

    Voted "Cleanest" 24 in the city. For the best workout, try cross fit and TRX training. Nick will kick your butt!
