CHARLOTTE -- At TITLE Boxing Club in Charlotte, folks aren't necessarily training for the next big Pay-Per-View match. Instead, they’re sweating for an hour in a small space where trainers help customers achieve results.

"It's more of a family environment, we're a close knit group," said the club’s General Manager Anthony Hill. "They're talking, they make friends, they're with trainers. People going to help them achieve their goals."

January's a time when more Americans are focused on getting healthy, and the trend of attending smaller studios is stronger than ever. And it's for all different types of classes, according to fitness subscription service ClassPass, The Queen City really liked strength training in 2017.

"Everyone's going 8 rounds with their own heavy bag," Hill said of the workout. "You get stronger, you're building metabolism."

Elsewhere in North Carolina, yoga dominates the ClassPass schedule in Raleigh. Emily Odioso, an intructor with Yoga One in Charlotte's Dilworth neighborhood, said there are a lot of reasons why people are ditching the big-box gym memberships.

"Being able to walk in, not being just a number, you're a person and a name when you walk in," Odioso explained. "We hold each other accountable, and we hold each other up to be bigger than yourself."

And if the idea of having to downward dog or upper cut in a more intimate space seems intimidating, think otherwise.

"We welcome everybody, every type of body, we have a tribe feeling here, so when you walk in the door we want you to feel like you're welcome and seen,” said Odioso.

"[We have] members as young as 8, as old as 74," said Hill. "People who look like your neighbors, people who look like your co-workers. Average, everyday people just trying to get healthy."

Market research company IBIS World reports the yoga, pilates, and personal trainer industry had a combined revenue of $20 billion in the U.S. last year.
