We launched our new mobile app and reservation system on May 30. With this new system, you are able to continue to make reservations for fitness classes and other activities. Unlike our previous reservation systems, this new product is connected to your membership account – ensuring you get earlier reservations options than non-members and continued access to virtual classes.

Download the new app in the App Store and on Google Play. Reservations open 50 hours in advance of the start time for members; 24 hours for non-members.

Y App Guide

In order to make reservations online and/or on the new mobile app, you will need to create an account with the email address we have on file for you.

In order to access the reservation system, everyone on your membership must use a unique email. This will prevent overbooking errors. For example, if you reserve a spot in a fitness class and your spouse reserves spot at the same time with your email, the system will think you are overbooking yourself. You must use separate email addresses. Only valid emails will be accepted.

If you would like to use a different email and/or add an email for other members in your family, please login to your Y account to update. If you don’t remember your login, please do not create a new account or you will create a duplicate account not tied to your membership.

Guests may also create an account online and/or on the mobile app. Members should not login as guests as guest access is restricted.

If you need assistance, we’re happy to help you next time you visit the Y. You may contact the welcome desk at your branch or email membership@ymcanoco.org.

Please note: We cannot accept reservations left on a voicemail.
