Basic-Fit bills its subscriptions in four-week periods, rather than by calendar month. This peculiarity results in thirteen payments per year instead of twelve, which alters the actual cost of access to the gym over a full year. Understanding this mechanism is the first step before choosing a plan or looking for a short-term option.
Billing by four-week period: the mechanism to know
Most gyms bill by the calendar month. Basic-Fit operates differently: each billing cycle lasts four weeks, or twenty-eight days. Over a year, this results in thirteen cycles instead of twelve months.

The difference may seem minor for a single payment. But over twelve months, a subscription priced at a given rate per four-week period amounts to paying an additional monthly fee compared to a competitor that bills by calendar month. This point is rarely highlighted on pricing pages.
An article detailing the prices of the Basic Fit 1-month subscription confirms that this four-week logic changes the interpretation of the actual annual budget.

Before comparing Basic-Fit prices with those of another brand, it is essential to convert the price to a common basis. Multiplying the displayed rate by thirteen, then dividing by twelve, gives the actual monthly cost over a year.

Basic-Fit Starter Kit: a prepaid pass, not a traditional subscription
Basic-Fit offers a product called Starter Kit on its webshop. This is not an automatically renewing subscription, but a one-time purchase that provides access to the gyms for a limited time.
This prepaid format appeals to athletes who want to test the network without commitment. The purchase is made online, on a separate page from the usual pricing grid. Once the payment is validated, access is activated for the period covered by the kit.
What the Starter Kit includes and excludes
The Starter Kit provides access to the basic equipment of a club. Services reserved for higher-tier plans (unlimited virtual classes, access to the entire European network, free guest) are generally not included.
- Access limited to a single club or a restricted area depending on the chosen plan
- Fixed duration without automatic renewal, preventing any surprises on the bank account
- No commitment period beyond the prepaid duration
For someone who wants to train occasionally, during vacations or a transitional period, this format represents the most financially transparent option.
Basic-Fit registration channels: website, app, and club counter
Registration does not only go through the pricing page of the website. Three channels coexist, and the process differs slightly depending on the one chosen.
Online registration on the website
The website basic-fit.com allows you to select a plan, enter your details, and validate the payment. A QR code is then generated to access the club. Activation is almost immediate after payment validation.
Registration via the mobile app
The Basic-Fit app, available on Android and iOS stores, offers the same registration process. It then serves as a support for the access QR code, session tracking, and contract management.
Registration at a club counter
Some clubs have a counter or kiosk that allows you to finalize registration on-site. This channel is suitable for those who prefer to check the equipment before committing, even for a short duration.
- The website and app provide access to the same plans and ongoing promotions
- Registration at the club allows you to ask questions to the staff, but the prices remain the same
- The QR code replaces the physical card in most recent clubs

Promotions and temporary offers: what really changes the price
Basic-Fit regularly launches promotional offers. Some include free access weeks upon subscription, others reduce registration fees or add an accessory (sports bag, for example).
These promotions alter the entry cost, not the recurring rate. An offer of two free weeks shifts the first payment but does not change the amount charged thereafter for each four-week cycle.
Referral and promo codes
Referral platforms list Basic-Fit offers that allow obtaining a benefit upon registration. Referral by an existing member can also entitle both parties to a one-time discount or bonus.
Before finalizing a registration, checking ongoing offers on the official website and on promo code platforms can sometimes save on initial fees. Registration fees are often the most negotiable item thanks to these promotions.
Basic-Fit prices by plan: Comfort and Premium
Basic-Fit structures its offer around two main plans. The Comfort plan provides access to a single club, while the Premium plan opens access to the entire network, including internationally.
The Premium rate is charged at a higher price per four-week period. In return, it includes additional services: access to all clubs in the network, the ability to bring a guest, unlimited virtual classes.
The choice between Comfort and Premium depends on travel frequency. An athlete who always trains at the same club has no financial interest in subscribing to the Premium plan. However, for someone who travels or wants to vary their gyms, the price difference quickly justifies itself.
Prices may vary from country to country within the Basic-Fit network. The rates displayed in Belgium or the Netherlands are not identical to those practiced in France, even for plans with the same name.
The actual price of a Basic-Fit subscription thus depends on three variables: the chosen plan, the duration of commitment (or the absence of commitment via the Starter Kit), and the active promotions at the time of registration. Bringing each option to a cost per week allows for objective comparison with other brands billing by calendar month.
