Group exercise classes inside our facilities

We do no longer have a ticket system for our group exercice classes.
The front desk will verify your booking upon arrival and let you in. The instructor will register when you arrive for the class. Please make sure you arrive early.

Group exercice outdoors or by another entrance

We do no longer have a ticket system for our group exercise classes. Show up where the class is held or use the alternate entrance. The class instructor will check you in. Please make sure you arrive early.

Waiting lists

Should the class or work out times fill up, you can join the waiting list by clicking the booking button. We will notify you of your number in line. Check «My bookings» to see updates of your spot in line.
There are often cancellations and they typically happen right before the cancellation deadline. We will send you an sms should a spot open up, so it is important that we have your cell phone number on file.


If you are not able to attend your booking, you may cancell it at the latest three hours before the booked time or class. You have to do it online or in the Mitt SiO app. If you are using a punch card, guest training or a free trial, please call us at 22 59 69 50.

Note: We appreciate that you cancel as early as possible, so that others may enjoy the training time.


If you do not show up for the booked work out session, or are late with the cancellation, you will be marked as a no-show. If this happens twice, you will not be able to book sessions online or in the app for the next 10 days. You can pay NOK 15 to have the booking ban removed. To remove the booking ban, you must contact one of our receptions.

Note: During the period you are banned from booking sessions online, you can book sessions from the reception from 60 min before the class/session starts.

What does it imply to be a member?
When you sign a membership with us, you have become a member of SiO Athletica´s gyms.
This means that you have an ongoing membership, and for the membership to be cancelled you must terminate it. Read more in our membership terms.

Do I have to be a student to use SiO Athletica?
Everyone can become a member of SiO Athletica, you don’t have to be a student.

Are all of SiO Athletica's gyms included in the membership?
Yes, when purchasing a membership you can workout at Athletica Blindern, Athletica Centrum, Athletica Domus, Athletica Nydalen, Athletica Vulkan and Athletica Kringsjå.
You can use the gym, swimming pool, multipurpose hall, the football field, attend group training classes etc at all of our clubs. If you have a swimming membership, you have access to the swimming pool at Athletica Domus before 13:00 on Mondays to Fridays. 

What is the age limit for training at SiO Athletica?
Everyone above 18 years can become a member of SiO Athletica. You are not allowed to bring children to SiO Athletica, except in specially organized activities with parents, such as family swimming.
Athletica Vulkan has a child care service during opening hours, read about the child care service here

Why does the membership price vary for students from different schools?
The reason why the membership price varies is related to the financial contributions to SiO Athletica from the different educational institutions.

I am not able to sign up for membership with student price online, although I am a student. Why?
The reason is that we have not registered a paid semester fee on your user. Stop by one of our receptions, and we will help you.

Because we are temporarily no longer able to provide you with the training offer that you have paid for, we have suspended the payment of your membership for the time being. You will therefore not be billed during the period we keep our clubs closed.

How much do I pay when I become a member?
When you decide to join us, you pay for the remaining days of the current month and the whole of next month when purchasing a membership. If you select a month to month membership you pay an additional start fee of 100 NOK when you sign up. See the pricelist.

How do I pay for my membership?
We offer direct debit (Avtalegiro) as an option for paying your membership. You can activate Avtalegiro on "My membership" on our website or in your online banking. A billing fee of 35 NOK will be added to your invoice if you don't activate Avtalegiro. 

What is Avtalegiro?
Avtalegiro is an automatic payment agreement between you and your bank. With Avtalegiro, the amount will be automatically deducted from your account each month. Note that this is only a way of paying for your membership, it is not enough to cancel the Avtalegiro to cancel your membership. 

How do I activate Avtalegiro?
The quickest way to activate Avtalegiro is on "My membership" on "My page". Click on "Activate Avtalegiro". After submitting your card details it will take 3 days until it is activated. 
You can also activate Avtalegiro manually in your online bank account. Fill in your personal KID number and Athletica's account number. The invoice date must be set to the 1st of each month. If you need help you can fill out an Avtalegiro form at one of our receptions. Note that by activating Avtalegiro this way, it can take up to 8 weeks to be active and you will be charged 35 NOK per invoice in the meantime.  

What is SiO Athletica´s bank account number?
The correct bank account for your Athletica membership is stated on your invoice. Please notice that a payment must contain the correct KID number to be associated with your invoices.

What is my KID-number?
Your KID-number is written on your last invoice. If you don’t have the agreement or an invoice, please contact one of our receptions or send us a message. You can also log in to My Page at and see your KID under "My finances". 

Why hasn't Avtalegiro been activated?
You are responsible for setting up the agreement with your bank. There might be other reasons to why Avtalegiro isn't active yet:

The Avtalegiro has just been created
It can take a few days for the Avtalegiro to be activated. If you sign the Avtalegiro form, it can take up to 8 weeks (depending on your bank).

There is already an Avtalegiro agreement in your bank account (perhaps from a previous membership)
If you already have an Avtalegiro agreement with us, your new agreement will not activate. In this case, you must delete your old agreement and create a new one. NB! Please allow 2 days from deleting an agreement to creating a new, to make sure the old agreement does not reactivate. 

There is an automated deduction set up each month instead of Avtalegiro
An automated deduction agreement is not the same as Avtalegiro. By having an automated deduction, you will still be sent an invoice with the additional invoice fee of 35 NOK each month.

Someone else owns the account 
The account owner must sign (both on paper and electronically) to activate the Avtalegiro. 

I have switched to another bank, what do I do with Avtalegiro?
Create a new Avtalegiro agreement in your new bank account and your old one will be deleted.

What happens if I have forgotten to pay, or my payment doesn’t show?
If you have an unpaid invoice that you can't locate, please contact us by talking to one of our receptions or send us a message.

We will help you retrieve the invoice so you are able to either pay directly at the reception or get your payment information. If the invoice is not paid within the deadline, the case will be sent to the debt collection company Modhi for payment tracking. If your invoice is due and submitted to Modhi, you must contact Modhi directly.

Notice that it will take a few days from paying until the payment is registered. If you have received a reminder, even though you have paid, send us a message which includes your payment information and receipt here.
