Sure, all you biceps-curling, muscle-loving junkies could break a sweat at any old gym in South Florida — but at Gold's Gym on Commercial Boulevard, every cardio machine will not be taken during rush hour when the business day ends; the sauna always works; and the gym contract isn't as binding as a marriage certificate. This facility has all the requisites — new cardio machines, complimentary classes in Boot Camp, Cardio Kickbox, and Zumba — plus a few extra-special touches. For instance, the staff is friendly (no frowning desk clerk hovering over you when it's ten minutes to close). The spinning room has black walls with neon decoration (how awesome is riding in the dark?). The agreements are reasonable (you pay your last month with your first, so simply give 60 days' notice and you're out). On top of all this, the cardio machines have iPod hookups (so your battery will never go dead again), and Gold's understands the ladies (there's a women-only workout area).
