Some people would argue that the best Jim is Jim Carrey. Or Jimmy Johnson. Maybe even Jiminy Cricket. But workout junkies in Kendall know the number one place to break a sweat is Thump Fight Gym, hidden in the lushly green Kings Creek Shopping Center. Since 1997, this seemingly rugged boxing gym — decked out with a ring, ample bags, and a loudmouthed coach — has been the perfect place for any gym rat. There are treadmills and stationary bikes for the hamster-wheel/exercise-machine set, weights for the beefcakes, yoga classes for the hippies, and spinning, CrossFit, boot camp, TRX, Thai boxing, and Brazilian jujitsu classes. What's more, this gym has a strong family vibe. Not only does owner Steve Arintok throw an annual barbecue for all gym members and staff, but also he's on site every day greeting each person by name. "Hello," heavyweight boxing and kickboxing champion James Warring. "Hello," IBF featherweight champ Stacey Reile, and if you give this place a whirl, "hello" to the future Jim "Cinderella Man" Braddock. Membership rates are $39 to $75 a month.
