Streets Fitness, Louisville

The trainers at Streets Fitness believe that to progress physically, fitness relies on variation. To that end, they encourage clients to explore the gym’s full stock of weight-training and cardio equipment, as well as its 40 weekly classes. The class selection includes self-defense training such as boxing and kickboxing, in which guests burn calories as they perfect their martial techniques and figure out their entrance theme songs. And circuit training and core-conditioning sessions are also available, including The Grid, a full-body cross-training workout that was voted one of the area's best workouts by the Daily Camera. Streets also offers one-on-one personal-training sessions, in which coaches fine-tune workouts depending on patrons' goals and the severity of their heavy-bag phobias.
