WAREHOUSE GYM LLC, Franklin

Warehouse Gym's spartan interior shouldn't be mistaken for a lack of amenities. Rather, it signifies that the owner's focus is exactly where it needs to be: on getting members as fit as possible. And if you look a bit closer, you'll see that there's no shortage of advanced workout equipment here. Take, for example, the olympic lifting platform, which doesn't bend or break when a heavy weight gets dropped on it, allowing exercises to lift and drop without fearing for the architecture. There's no shortage of dumbbells and kettlebells, but there's also an impressive array of strength and cardio machines that target specific muscle groups. The collection of equipment even includes strong man tires, slam balls, and sledge hammers for less traditional workouts, such as whack-a-mole.
