Stellar Bodies is a fitness studio which offers a unique Pilates-based exercise technique called SPX to customers in the greater Atlanta area. SPX workouts last 50 minutes, and utilize a machine called the Megaformer which works both the upper and lower body through the resistance and counter resistance of springs and pulleys. Customers can sign up for either group or private lessons, as well as a membership providing unlimited classes and 30-day workout packages; Stellar Bodies also offers the customer's initial session free of charge.
