Groove Fitness is a full-service gym, offering classes, a huge equipment selection and much more. There are plenty of gyms in Los Angels, but Groove has two features that set it apart: it's open 24 hours a day, seven days a week; and it has a live DJ playing his own upbeat set list and even taking requests. Though the outside is nothing special, inside is a bright, airy, modern gym that's well-kept and features state-of-the-art equipment. There's also a steam room and a dry sauna. The gym offers a full range of classes, from yoga to aerobics. The front entrance is locked, so enter through the attached parking lot.
