Memberships, packages, and single entries serve different needs. People who travel, work shifts, or want to try an activity may seek occasional access; regular attendees may find a recurring option more suitable.
Gym listings often use terms such as single entry, day pass, open gym, and drop-in. Usage is not standardised: this guide is a glossary, while the linked article at the end covers the economic comparison with membership.
What one platform's data shows
In its 2025 Look Back Report, ClassPass recorded 51% year-over-year growth for Gym Time on its platform and named Pilates its most-booked activity for a third year. These are ClassPass platform data: they describe its audience and do not by themselves prove a market-wide preference or explain what caused the bookings.
The result is a useful signal to consider alongside prices, availability, and observed demand in your own city.
What does "drop-in" mean in fitness?
In fitness, “drop-in” is used for occasional access without recurring membership. It often refers to one class, but some venues also use it for open gym or a day pass: the label alone does not define what is included.
A trial class may have its own promotional terms or requirements; a drop-in is normally a one-off purchase at the published price. In either case, check registration, documents, cancellation, and included services.
The differences: single entry, open gym, day pass, and drop-in
The terms overlap, and each venue may use them slightly differently. These definitions are a guide: the session listing always takes precedence.
1. Single entry and open gym
Single entry describes a one-off payment, while open gym describes independent training. They may appear in the same offer, but they are not necessarily synonyms.
- What it may include: access to the stated areas for the published duration and times, subject to venue restrictions.
- Who it's ideal for: For those who already have their own workout plan, know their way around the weight room, and only need the equipment.
2. The gym day pass
The term day pass suggests access valid during a day or part of that day, but duration and number of entries should be checked.
- What it may include: the fitness area and, only when stated, additional amenities or classes. A pool, spa, and multiple entries are not implied by the label.
- Who it's ideal for: For those who want to dedicate a full day to wellness, perhaps during a weekend getaway.
3. The drop-in class
When it refers to a class, a drop-in reserves a place in a specific scheduled session once the booking is confirmed.
- What it includes: Participation in a specific class (e.g., Pilates Reformer or Functional Training) led by an instructor.
- Who it's ideal for: For those who want to be guided by a professional, love the energy of a group, or wish to try a new discipline.
When does it really make sense to work out without a membership?
To decide whether it is worthwhile, compare the total cost of the entries you would actually use with equivalent memberships and packages. Single access may suit you if:
- You travel often: occasional access may be more practical when you stay in a city for short periods.
- You have unpredictable schedules: If you work shifts, you might not be able to attend classes at the usual times. Paying individually allows you to train only when you are available.
- You want a hybrid workout: You work out at home or outdoors, but need a gym 1 or 2 times a week to lift heavy weights.
A model for all ages
ACSM's 2026 Fitness Trends ranks fitness programs for older adults second among the surveyed trends. This signals attention to the audience but does not show that drop-ins are its preferred format. At any age, the choice should reflect continuity, required support, health considerations, and actual value.
