Basic-Fit claims a dense network of gyms in France, and the temptation to lend your card to a friend or share your credentials exists. However, the general conditions of the brand, updated on May 1, 2026, strictly regulate the use of each subscription. Between the plans that provide for an invitation mechanism and the practices that expose one to cancellation, the boundary deserves to be clearly established.
Personalized card and QR code: what the contract technically prohibits
Each Basic-Fit subscription is linked to a unique profile. The physical card, the QR code generated in the app, and any biometric data (face scan in some clubs) are used to verify that the person checking in is indeed the contract holder.

Lending your card to a spouse, an adult child, or a friend constitutes a breach of the general conditions. The internal regulations specify that access to the club is strictly personal and non-transferable. In the event of a check, Basic-Fit can suspend or terminate the subscription without refunding the remaining monthly payments.
The question regularly comes up on forums and TikTok, where videos offer “tips” for entering for free. These methods (sharing QR codes, exchanging cards between members) constitute a contractual violation. Before exploring these avenues, it is better to understand the options that the brand offers to share your Basic Fit subscription with your family within the framework provided by the contract.

Comfort and Premium plans: the legal invitation mechanism at Basic-Fit
Basic-Fit has integrated a feature into its higher-tier offers that directly addresses the need to bring a guest. The Comfort and Premium subscriptions include the possibility of inviting a guest to each session, at no additional cost upon entry.
The guest must be accompanied by the holder. They cannot present themselves alone at the club with the member’s card or QR code. Before accessing the facilities, the guest must be registered at the reception or via the app, in accordance with Article 6.c of the general conditions.
This system allows a couple or a parent with their adult child to train together on a single subscription. The limit is clear: only one guest per visit, and this person must enter and exit with the holder.
What the invitation does not cover
- The guest does not have a personal profile in the app and cannot track their performance or book group classes in their name
- If the holder wishes to alternate between several guests (spouse one day, child the next), each guest must be registered individually during their first visit
- Access to virtual group classes (GXR) and certain premium areas may be limited for the accompanying person depending on the club
Minors in the family: parental permission and minimum age at Basic-Fit
Bringing a teenager to the gym raises a distinct question. Basic-Fit accepts members from the age of 16 under certain conditions. The minor aged 16 or 17 must provide written parental permission at the time of registration, and this registration requires the subscription of a contract in their own name.
In other words, a parent holding a Premium subscription can occasionally invite their 16-year-old child through the accompanying mechanism, but for regular and independent access, the teenager needs their own contract signed by a legal representative.
For children under 16, Basic-Fit does not allow access to the clubs, even when accompanied. This rule does not allow for any contractual exceptions. Families with younger children must turn to other facilities (municipal gyms, sports associations) that offer suitable time slots.
Starter Kit and multiple subscriptions: alternatives to card sharing
Rather than risking cancellation by lending your card, several contractual options allow you to introduce Basic-Fit to your family.
The Starter Kit offers one month of access without commitment, purchasable online. Each family member can subscribe to their own to test the gym individually before choosing a lasting plan. This is a legal solution to assess whether the investment in a Comfort or Premium subscription with a guest is justified.
- A couple who always trains together can make do with a single Premium subscription (the holder systematically invites their partner)
- Two members of the same family who want different schedules will need two separate subscriptions, even basic ones
- A parent and a teenager aged 16 or older can opt for two separate subscriptions, with the required parental permission for the minor
The economic calculation depends on the frequency and autonomy desired by each household member. A Premium subscription with unlimited guest access is cheaper than two basic subscriptions if both individuals always come at the same times.
Concrete risks in case of unauthorized sharing
Field reports vary on the severity of checks depending on the clubs. Some gyms have turnstiles with facial scanning, while others limit themselves to the QR code on smartphones. The detection of fraudulent use therefore largely depends on local equipment.
However, the contractual consequences are uniform. The general conditions provide for the immediate termination of the contract, without refunding the current month or any prepaid months. The offending member may also be prohibited from any new registration in the Basic-Fit network.
The temptation to share cards reflects a real need, to which the Comfort and Premium plans provide a regulated response. For families, the real trade-off is between the cost of a higher subscription with a guest and that of two separate subscriptions, depending on each person’s training habits.
