The Planet Fitness Lunk Alarm is a loud siren and flashing light used to discourage disruptive gym behavior, like loud grunting or dropping weights, helping the chain maintain its “Judgement Free Zone” atmosphere. If you’ve ever heard a sudden alarm blaring in a gym or seen the blue light flash at Planet Fitness, you’ve witnessed the Lunk Alarm in action.
Understanding how the Lunk Alarm works—and its recent changes—is important for both new and regular members. This guide explains everything you need to know: why the Lunk Alarm exists, how it’s used, recent policy changes, and what to expect if your club still has one.
What Is the Planet Fitness Lunk Alarm?
Planet Fitness, known for its welcoming “Judgement Free Zone®,” introduced the Lunk Alarm to discourage intimidating or disruptive behavior. The term “lunk” describes someone who grunts loudly, drops weights, or engages in showy, attention-seeking actions that might make others uncomfortable.
The Lunk Alarm is a wall-mounted siren with a flashing light, usually near the free weights section. When triggered by staff, it draws attention to the disruptive behavior and reminds everyone of the gym’s inclusive policy.
- Definition of a “lunk” at Planet Fitness:
- Grunting loudly
- Slamming or dropping weights
- Acting aggressively or drawing attention to oneself
- Wearing tank tops that expose too much (in some locations)

How Does the Lunk Alarm Work in 2025?
Is the Lunk Alarm Still Used?
As of 2025, the Lunk Alarm is still present in many Planet Fitness locations, but its usage is declining. Some new gyms no longer install it, and several older locations are removing or rarely using it. The company is gradually shifting toward a more modern, inclusive approach.
- Recent changes (2024–2025):
- Many new clubs are being built without the Lunk Alarm.
- Older clubs have either stopped using it or now use it only as a last resort.
- Staff are encouraged to give members multiple reminders before activating the alarm.
According to Reddit discussions in 2025, multiple users report their new gyms don’t have the Lunk Alarm, and some staff mention it’s mostly a “symbolic” feature now (Reddit, 2025).
When Is the Lunk Alarm Triggered?
- Only after repeated disruptive behavior (not for a single mistake)
- Usually after staff give at least one or two friendly warnings
- Used for extreme cases, such as loud shouting or repeated weight-dropping
You won’t get “lunked” for being a beginner or making a mistake—staff are trained to use judgment and discretion.
Why Is the Lunk Alarm So Controversial?
Supporters Say:
- The alarm makes the gym more comfortable for beginners and non-bodybuilders.
- It reinforces the “Judgement Free Zone” policy, helping everyone feel welcome.
Critics Argue:
- The alarm can embarrass or single out members unnecessarily.
- Some say it discourages serious lifters or those who naturally grunt.
- A petition on Change.org calls for a more inclusive and nuanced policy (2024–2025).
Public sentiment is shifting. Many members now believe that enforcing basic gym etiquette through conversation is more effective than a siren. Even some club managers agree the Lunk Alarm is outdated and doesn’t reflect current gym culture.

- Know the Rules
