Planet Fitness is a pathetic fascist unisex version of Curves. They're a joke.
The "no grunting" alarm will go off is you so much as breathe loudly on a set of dumbbell rows, and their staff are the reject desk monkeys of Lifestyle and 24 Hour and Bally's and you'll note - THEY don't work out there.
I've been to some because they were the only option when traveling, and I watched them treat some serious non-grunting, non-groaning, perfectly appropriately attired serious lifters like criminals because, quite simply, they found them intimidatingly over-zealous (i.e. lifting weight heavier than 25 pounds and breaking a sweat).
The ads are clever, but the clubs have all the atmosphere of a frozen food section at the grocery store and near next to nobody who is remotely serious about their conditioning and training.
As a buddy on RJ once wrote me "the fucking Fitness industry ruined bodybuilding". Amen.
Edit: Maybe your club is an anomaly, Mikeylikesit. But the handfull I've entered were better off being beauty salons than gyms.
