Our Approach With over 100 people a day moving to Nashville, 615Fitness is your connection to all things fitness including center, personal trainers, events, and nutrition. Our Story Being new to the Nashville area, it was a struggle to find a place to work out and find a trainer that aligned with our goals. We wanted a one stop shop for the fitness community to come together and share experiences and recommendations. As the site continues to evolve, fitness and trainer recommendations will be sought in addition to offering apparel.
