(CBS) WAPPINGERS FALLS, N.Y. You can lift, strain, crunch and sweat all you want at the Planet Fitness in the Dutchess County village. But whatever you do, do not grunt. Yep, "no grunting." It says so, in black and white, on a sign posted at the gym. One former member learned the new rule the hard way. "This is really absurd, especially the part about the grunting," said Al Argibay, a corrections officer who learned first-hand "no grunting" means exactly that. Argibay, a former competitive bodybuilder, joined the gym in September because it was affordable and convenient.
