Poli Moronari started Nova Fitness in 2020, and has built a loyal following. When Poli Moronari received an offer to take over a fitness space in Watertown, she took the opportunity to take her personal training business to the next level and start a fitness studio for women. Moronari started Nova Fitness, at 222 Arsenal St., in 2020 and has built a following. She offers Pilates instruction, weight lifting with machines and exercises with kettlebells and dumbells, but one thing that sets her apart, Moranari said, is that focuses on each person’s individual needs. The most she has in a class at one time is six people, and sometimes all six are working on the same thing while other times each person has their own workout.
