Ever been working out at a gym, only to get distracted by some annoying person grunting and groaning?

Well, it's nice to see that Planet Fitness gyms will do something about it.  Planet Fitness gyms are known for their policies — one too many offending noises can get a membership revoked in the time it takes to do a sit-up. Nationwide, the chain expels roughly two members a month for various reasons, most commonly grunting and dropping weights.  The no-grunt policy is one of several eyebrow-raising rules — no bandannas, no jeans, no banging weights — that managers say are intended to make their target clientele of novice exercisers feel comfortable.
