ACTON, MA — btone FITNESS, the fast-growing boutique fitness brand known for its unique blend of Pilates-inspired movements and strength training, has officially opened its newest studio in Acton, Massachusetts. Located at 389 Massachusetts Avenue in the Acton Plaza, the 2,200-square-foot space is one of the largest in the btone portfolio. A grand opening celebration is scheduled for the weekend of July 11.
The Acton location is owned and operated by Suzanne Thornfeldt, a seasoned btone studio owner and Wayland resident. Thornfeldt, a former Division I athlete, already owns the successful btone Wayland location and brings years of experience as an instructor and brand ambassador. She says the Acton studio fills a much-needed niche in the community.
“Acton just feels like the perfect home for a new btone FITNESS studio,” said Thornfeldt. “There’s nothing else like it in the market, and our location in the Acton Plaza can’t be beat. We look forward to welcoming neighbors, friends, and new clients to discover what makes btone so different.”
The new studio features 12 customized reformers, exclusive to btone FITNESS and affectionately known as TONEy. These machines allow clients to modify resistance and positioning, delivering a highly personalized, full-body workout in just 45 minutes. The signature TONE class blends functional movement, strength training, and Pilates-inspired exercises, designed for people of all fitness levels. The Acton location will also offer ample parking and childcare services for added convenience.
Founded by Jody Merrill, btone FITNESS has experienced rapid expansion in recent years. Starting with seven locations in 2022, the company grew to 22 by the end of 2024. With 23 studios now open and 19 franchise partners across the U.S., Merrill says the brand is on track to operate nearly 40 locations nationwide by the end of 2025.
“Our goal is to bring smart, efficient fitness to more communities—and Acton is a key part of that growth,” said Merrill. “We combine the principles of Pilates with modern strength training and functional movement for maximum results. This is the 45-minute workout people don’t want to miss.”
btone FITNESS studios are currently located throughout New England, including in Boston, Hartford, and Providence, with new locations opening soon in Dorchester, Southborough, Newport, East Greenwich, and Portland, Maine. Additional markets being scouted include New Hampshire, New York, North Carolina, Florida, and Pennsylvania.
