Whatever you’re looking for to take your fitness further, you’ll find it at our North Knoxville location on Merchants Drive. Want to catch a movie while getting in a session on the elliptical? Want to run laps? We have a track indoors, so the weather never gets in the way. Want to get together with friends to shoot some hoops or play racquetball? We have courts for that too! Only have 30 minutes, but want a full-body workout? We have circuit training stations. Want to commit to a fitness program, but there’s no one to watch the kids? We have free, onsite childcare to keep your kiddos happy while we help you smash your goals. We’re also here for you from 5 a.m. until 11 p.m. each Monday through Friday and 7 a.m. - 7 p.m. Saturday and Sunday! We know schedules can be hectic, so we want to help you get closer to your fitness vision whenever it works for you, and however it works for you. In addition to a range of individual workout options, we offer group classes, like body pump and yoga.
