Simple Fitness

Simple Fitness is a boutique fitness center in Melrose built around small group coaching. Its classes mix high-intensity interval training, cardio and weight lifting, with weight loss, strength and endurance as the main goals. The space is meant for people of every experience level, and the gym stresses a peaceful, judgment-free atmosphere where members are treated like family. Clients can come once, three times a week, or sign up for unlimited sessions.

The gym is run by owner and trainer Andreia Oliveira, known to members as Deia, a certified personal and group fitness trainer and CrossFit Level 1 trainer. She designs the group workouts herself and focuses on sustainable progress and healthy habits for long-term success. Members credit her with pushing them through the exercises they find hardest.
