pparently at Planet Fitness in the Dutchess County village of New York, you can lift, squat, crunch and sweat all you want. But whatever you do, do not grunt.

In fact, the no-grunting policy is readily displayed, along with "no bandannas, do-rags, or screaming," on the long list of dos-and-don'ts posted right inside the Planet Fitness door.

Sound like some kind of joke? Well just ask Al Argibay, a corrections officer, who learned first-hand how serious the gym is about their "no-grunting" policy. His membership from the gym was revoked as a result.

Argibay said he was at a multi-press station, getting ready to squat about 500 pounds when he committed one of the gym's cardinal sins. "I let out a grunt, squatted down, back up, grunt again. That's it," explained Argibay. "Basically, grunt, grunt, basic breathing in heavy, and breathing out."

Planet Fitness, which discourages so-called "musclehead behavior," even has a flashing light and siren on the wall, labeled a "lunk alarm," which sounds if someone grunts or drops weights on the floor.

Carol Palazzolo, the gym manager, who yanked Argibay's membership on Monday, said, "We're creating an atmosphere that's not intimidating."

According to the Wappingers Falls police report, officers were asked to "escort a member out of the club for grunting while working out...which is not conforming with the rules of the establishment."

Of the incident, Palazzolo said, "I'm not out to hurt anybody. If he feels I hurt his feelings, I apologize for that, but I do not apologize for the way I handled the situation and I am not apologizing for our etiquette at Planet Fitness."
