One who grunts, roars, drop weights, and basically annoys the hell out of everyone else in the gym.
Mark is always slamming his weights, roaring like a lion, prancing around in his muscle shirt like Mr. Olympia! What a gym lunk!

Planet Fitness's 110dB deafening tornado siren. An employee sets it off when they hear weights drop or someone tattles on another member for using a cell phone in the gym area.
The offender is not singled out (and may not even know it's sounding for them).

Other innocent members get blasted with the ear piercing siren, which is above the OSHA sound level limits. The only effect of the Lunk Alarm is to damage members' ears (the employees at the trigger switch are far away from the sound).
Lunk Alarm, siren, OSHA

Get the Lunk Alarm neck gaiter and mug.
Something made up by the insecure people who run Planet Fitness (Planet Fatness) gyms. They set it off when anyone remotely dedicated to training is in the area. They claim to be a "judgement-free" gym, yet ironically they won't even let those who they deem "lunks" into their facility. The people don't want to "be intimidated" by fit gym goers, yet the only thing intimidating them is their own insecurities.

A lunk head is (usually male) someone who lacks creativity, is very slow on the uptake on understanding situations, is not well read or well informed politically or intellectually, is most likely barely literate, has not desire to educate themselves, no intellectual activity, has no ability to plan for the future, and has very little perception skills, if they do read anything, it is usually a low level tabloid newspaper, has no hobbies outside of watching televison. Possibly half the male population fits this category. Often overweight.
A subway worker in New York City named Mike, a barely literate, uneducated, very very slow mentally, proudly claims that "he hates to read", but will read the sports section in the New York Post. Has no concept or interest in politics, foreign affairs, science, hobbies, social customs, no interest in travelling abroad, proudly claims that he "has no need for a passport" Only goal in life is to retire with a pension. No desire to own property, often breaks telephones due to spending his entire 8 hour shift talkin to other lunk heads.
