Your typical gym is crowded at rush hour, smells of antiseptic, and plays a rotating soundtrack of groaning jocks and bad house music. It's pricey too. Commissioner Marc Sarnoff should know. He works out at Coral Gables' Equinox, which, for a base rate of $129, could probably keep a few of those laid-off city employees on the ledger. So in November, he used some of his quality-of-life funding — nearly $30,000 — to create the antithesis to Equinox: an outdoor gym. Located at Kennedy Park, a jog away from city hall, the gym is equipped with all the basic workout gear: a couple of sit-up benches, a leg press, monkey bars, and several elliptical and rowing machines. Out in the open, the Crayola-green equipment is constantly in use, seven days a week. It's not hard to see why. The only shrill noise you're likely to hear is kids playing or the occasional Frisbee zipping by. And there's a bonus: Sarnoff still works out at Equinox, so you won't have to see him doing squats on an otherwise beautiful afternoon. Open since November, the gym has been so popular that Sarnoff wants to install similar ones at Margaret Pace and Legion parks.
