Studio owner Marissa Rubinetti

Studio Owner

Marissa Rubinetti

Marissa Rubinetti came to barre3 in 2018 as a single mom of two young boys, looking for a way to reconnect with herself after putting her own wellbeing on hold. She fell in love with the practice in her very first class and, a year later, auditioned to become an instructor. 

What she loves most about barre3 is its community — she has never belonged to a fitness studio that made her feel so welcomed, valued, and comfortable in her own skin, with workouts that are challenging yet always attainable. Barre3 has taught her to stay in tune with what her body needs, and to give herself grace to meet herself where she is each day. 

Marissa is a strong supporter of women’s health and wellbeing, and helping women become the best versions of themselves — mentally and physically — is something she deeply believes in. Becoming a studio owner has been a dream she’d carried for years, and stepping into this role now still feels like a pinch-me moment. Marissa spent 20 years as a merchant at David’s Bridal corporate before serving as Chief Operating Officer and Executive Vice President at Kleinfeld Bridal in New York City. 

Originally from New York, she moved to Pennsylvania at 21 and now lives there with her sons, Derek (12) and Cole (11), her husband Edward, and their golden retriever, Rocky.

You'll find barre3 Rosemont on Lancaster Avenue in Rosemont Square, alongside Gullifty's, the scratch kitchen that opened here in 1975 and has churned its own ice cream since 2010. The Rosemont station on SEPTA's Paoli/Thorndale line is a short walk north, an easy ride into Center City. Just past the tracks on Montgomery Avenue, Ashbridge Park keeps tennis and pickleball courts, a playground, and a story walk posted page by page along its trail. Stop by before a walk at the park, or make barre3 the anchor of your week.

Our barre3 Rosemont studio offers everything you need for a balanced practice. Barre3 Signature blends strength, cardio, and mindfulness into one complete full-body workout, using the barre, core ball, and weights to build strength, increase flexibility, and sharpen balance. B3 Strength is the deeper muscle work—heavier weights and slow, deliberate movement that builds the kind of strength you feel in your everyday life. B3 Cardio brings the heat—a high-energy, full-body push that leaves you feeling accomplished and clear-headed, not wiped out. B3 Mindful Flow uses breath-driven movement to restore your body and build the mobility and ease your body needs to keep up with your life. You'll leave feeling stronger and more capable than when you walked in. Every fitness level is welcome.
