The dedicated staff and members of Total Body Trifecta Fitness Studio celebrated a milestone Sunday, marking the 12th anniversary of the business’s opening on the West side of town.

As a small and unassuming studio at 61 Lawrence St., Total Body Trifecta has weathered the years despite roadblocks like fire and recession.

Longtime members laud the sense of community created there by co-owners Mary Anne Fantauzzi and Brian Bayly, who’ve worked together for more than 15 years.

“We figured we might as well do what we do best, which is teach class,” Fantauzzi said of the partnership with Bayly that began years ago at Saratoga Athletic Club on West Avenue.

“We decided we’d make a go of it,” Bayly added.

Both are certified personal trainers. Fantauzzi specializes in the New York City Ballet workout and Bayly is a practicing dancer himself, appearing locally in performances like “The Nutcracker.”

Along with about 10 other certified instructors, they teach fitness classes in everything from low-impact aerobics, pilates, kick-boxing, yoga, ballet and salsa, seven days a week.

They call Total Body Trifecta its own family, counting less than 100 people between staff and members, who range from college students to Baby Boomers; 99 percent of them are female.

The location of the studio has changed throughout the years, but the business has survived with adaptability, said Bayly and Fantauzzi, who both maintain non-related full-time jobs in the area.

A fire started by a curling iron in a former rented space on Lawrence Street burned that building to the ground, so Total Body Trifecta moved next door to the Freeman & Shea Plumbing building, a converted carriage house where oddities like an antique safe and original flooring from the Grand Union Hotel share space with mats and exercise balls.

Currently, the studio offers walk-in classes, class cards and month-by-month membership.

“We’re changing with the times to adapt,” Fantauzzi said. “This way, people have the flexibility to do a class without making a big commitment.”
