Time tracking in gyms and sports centers

Time tracking in gyms: when schedules don’t follow a pattern

Instructors teaching three classes a day at different times. Personal trainers with schedules that change every week based on demand. Receptionists working rotating shifts from 7:00 AM to 11:00 PM. Cleaning staff arriving before opening and leaving after closing.

Gyms and sports centers have one of the trickiest workforce scheduling challenges out there. Yet many still track hours with Excel spreadsheets, paper schedules, or simply trust that “everyone knows when they start and finish.”

That works until it doesn’t — usually when a labor inspection arrives or an employee claims overtime that nobody recorded.

A real case: 1,200 overtime hours claimed at a sports federation

The STSJ Catalonia 173/2026 ruling perfectly illustrates the problem. An employee sued the Catalan Winter Sports Federation claiming more than 1,200 overtime hours she said she had worked without being paid.

The organization didn’t have a reliable time tracking system. It couldn’t prove how many hours the employee had actually worked. And here’s the key point: without time records, the burden of proof is reversed. It’s the employer who must prove those overtime hours weren’t worked, not the employee who must prove they were.

In this particular case, the court found that the claimed overtime hours were not sufficiently proven. But the judicial wear, lawyer costs, and uncertainty of the process are a price no sports organization should have to pay — especially when the solution is as simple as implementing a digital time tracking system.

Key takeaway: Even when the company wins the case, the process is long and expensive. A digital time tracking system would have prevented the lawsuit entirely.

Why gyms are especially vulnerable

The fitness and sports center industry brings together several complications that make time tracking especially difficult:

Fragmented work schedules

A spinning instructor might teach a class from 7:00 to 8:00 AM, another from 1:00 to 2:00 PM, and a final one from 7:00 to 8:00 PM. That’s three hours of actual work, spread across three time slots over 13 hours. The time tracking system must support multiple clock-ins and clock-outs in a single day and correctly calculate total hours.

Part-time contracts with supplementary hours

It’s common for instructors to have contracts for 20 or 25 hours per week, but work more during peak demand periods (September, January after the holidays, pre-summer). Those additional hours are supplementary hours that must be recorded and paid according to the collective agreement.

Without precise records, it’s impossible to know whether an employee is within their contracted hours or has already exceeded them.

High seasonality

Gyms see membership peaks in January and September, and lows in summer. This means staffing levels fluctuate: temporary reinforcements are hired who need to clock in from day one. A time tracking system must allow quick employee onboarding without administrative processes that slow down day-to-day work.

Staff across multiple locations

Many gym chains (or freelance instructors working with several centers) need to manage time tracking at different locations. A trainer might teach morning classes at one center and afternoon classes at another. The system must be able to differentiate locations without complicating the process for the worker.

Group classes with changing schedules

The group class timetable (yoga, CrossFit, pilates, spinning, zumba…) changes frequently. An instructor might cover a last-minute substitution or add an extra class if there’s demand. These changes need to be reflected in time records automatically.

What the law says for sports centers

Time tracking is mandatory for all employees, no matter the industry. This includes:

• Hired instructors and trainers (including part-time)
• Receptionists and administrative staff
• Cleaning and maintenance personnel
• Lifeguards (at centers with pools)
• Hired physiotherapists and nutritionists

The new Royal Decree on time tracking, currently being processed, will additionally require that records be digital and interoperable, with remote access for the Labor Inspectorate.

Legal note: The Royal Decree is in the processing phase and has not yet been published in the BOE (Official State Gazette). Companies must already comply with the existing recording obligation (RDL 8/2019).

What about freelance instructors?

Personal trainers and instructors who work as freelancers are not required to track their hours. But be careful: if the working relationship looks more like a disguised employment contract (fixed schedules, exclusivity, direct instructions from the gym), the Inspectorate may determine there’s a false freelancer situation — and the consequences are far worse than not having time records.

How to implement time tracking in a gym

The good news is that a gym doesn’t need a complex or expensive system. It just needs one that adapts to its reality:

1. Mobile clock-in

Instructors enter and leave the center multiple times a day. Forcing them to use a fixed clock-in point each time is impractical. With a mobile clock-in app, they can record arrivals and departures from anywhere in the center — or even before arriving, if they have classes at external facilities.

2. Kiosk mode for reception

A tablet at reception with kiosk mode allows all staff to clock in upon arrival, without needing to install anything on their phones. It’s ideal for employees who rotate frequently or temporary staff who are only there for a few days.

3. Multiple clock-ins per day

The system must allow recording multiple entries and exits in a single day and correctly total the hours. None of that “one clock-in and one clock-out” approach used in standard offices.

4. Supplementary hours control

For part-time contracts (the majority in gyms), the system should alert when contracted hours are exceeded and automatically calculate supplementary hours, distinguishing them from overtime.

5. Reports by center and by employee

If you have multiple centers, you need consolidated reports showing each employee’s hours at each location, plus a total summary. You’re going to need this for payroll and for any Labor Inspectorate request.

How much does not having time tracking cost

The consequences of not having time records at a gym go beyond fines:

• Labor Inspectorate fines: From €751 to €7,500 per violation (with the new Royal Decree, up to €10,000 per employee)
• Overtime claims: Without records, the burden of proof is reversed and the company must prove the employee didn’t work those hours
• Internal conflicts: Disputes about schedules, substitutions, and hours worked that are avoided with objective records
• Part-time contract issues: The law already requires a specific hour log for part-time workers (art. 12.4.c Workers’ Statute). Without it, the contract is presumed to be full-time — yes, you read that right

Frequently asked questions

Is time tracking mandatory in a gym?

Yes. Time tracking is mandatory for all employees since 2019 (RDL 8/2019). It doesn’t matter whether it’s a gym, a chain of sports centers, or a small CrossFit box. If you have hired employees, they must clock in.

Do freelance instructors have to clock in?

No. Freelance workers are not required to track their hours. But watch out: if a “freelance” instructor has a fixed schedule, works exclusively for your center, and receives direct instructions, the Inspectorate may determine it’s a false freelancer situation — with far worse consequences.

How do you manage time tracking for instructors with fragmented schedules?

With a system that allows multiple clock-ins and clock-outs per day. An instructor might teach a class at 8:00 AM, another at 1:00 PM, and another at 8:00 PM. The system must record each segment separately and total the hours automatically. Time tracking apps like Cleverfy are designed for exactly this.

What happens if a part-time employee works more hours than contracted?

The additional hours are supplementary hours and must be recorded and paid according to the collective agreement. Without precise records, it’s impossible to control whether someone has exceeded their hours. And remember: if you don’t keep hour records for your part-time workers, the contract is presumed to be full-time (art. 12.4.c Workers’ Statute).
