 Members must now our Fitness Advantage app to access the gym.

This change will bring improvements to overall ease in accessing the gym. If you have any trouble please contact us for assistance!

If you're having difficulties accessing the gym with the new app, we have included some steps to follow below. At your convenience, follow the steps carefully. We suggest opening this email on a separate device and following thoroughly along with your phone. We are aware and apologize that there are some app glitches currently, which adds some frustration (GymFlow is working on this!). Ultimately though, this new app will make entering the gym much easier. Hang in there as you figure it out and let us know if you have any questions.

PLEASE carefully follow the directions:


If you currently have the KISI app, delete it.

In your phone find or search for the “App Store” 

(You need to know your Apple password to download apps)

In the App Store search: Fitness Advantage


To access the Gym please follow the following steps:

Download the Fitness Advantage app for iOS or Android


Sign in, using the SAME e-mail you joined with. If you are not 100% sure which email you initially used, please contact us first.


If you know your email but not your password, click "forgot password" and you will get an e-mail with directions to reset it in the GymFlow app.


Once you reset it, return back to the Fitness Advantage app and sign in. Then:


  1. Tap "Profile"

  2. Tap "Access"

  3. Follow the prompts.

  4. Be SURE to enable location and bluetooth access (it should prompt you to allow these)


Once set up, you will be able to access to the door by simply tapping your phone against the reader by the front door. There is a current glitch that may not allow this to happen (yet).


There is another glitch where the apple wallet app opens for some people.


If you encounter these above issues, open the app, tap profile, tap access, then hold phone up. Where it says "Gym Door" tap "Unlock" and that should do it.
