Fit Truk has traded its hometown workout circuit for a manufacturing floor and an international sales map. The Kansas City-born company is now producing custom-built mobile gyms for clients across the country and abroad.
“We have three different models of trucks,” said Josh Guffey, co-founder of Fit Truk. “We have trucks going out all over the U.S., and we’re going to be going out globally soon, working on several deals.”
The three models — the Fit Truk 1.0, 2.0, and 3.0 — range from $190,000 to $360,000. Six have sold so far this year, on pace to reach 12 to 15 by December. The company sold just two in 2024, making 2025’s projected numbers a sharp jump. Year-to-date revenue already totals $1.3 million.
The company began in 2021 as an extension of co-founder Hailee Bland Walsh’s City Gym, offering outdoor workouts from a converted GMC ambulance. Interest from other fitness professionals, brands, and organizations quickly began flooding in.
“We started having people from all over the U.S. and then all over the world reach out asking if we were a franchise, if they could buy trucks,” Guffey recalled. “That’s when we switched gears and started building trucks for others.”
Bland Walsh said that pivot came with a big shift in identity.
“We sell trucks,” she said plainly. “We build custom-made trucks for existing wellness businesses, whether those are sole proprietors or brick and mortar businesses, supplement companies, both here and around the world.”

Built close to home, sent far away
After early production in Wisconsin, Fit Truk moved manufacturing to Excelsior Springs, Missouri. This allows the team to monitor quality closely and make fast improvements.
“Our product quality has increased and changed so much,” Guffey said. “We’ve gone to a lot of poly materials instead of using lumber that is lighter and stronger, better actuator systems, better lighting systems. We’ve been able to really innovate since we brought the manufacturing back here.”
The smallest model uses a Mercedes Sprinter chassis, the mid-size is based on an Isuzu, and the largest includes a climate-controlled office space. Each unit is solar powered, GPS tracked, and equipped with security and camera systems.
One recent delivery went to 1st Phorm, a St. Louis-based supplement company known for building its brand through community events.
“It’s a rolling supplement show and community activation tool,” Guffey explained. “Their truck is going to be traveling around the country, doing events and promoting their brand.”
Beyond supplement companies, Fit Truk is talking with universities, military units, and touring musicians. Guffey recalled setting up backstage at the Country Stampede music festival.
“They’re all hauling random equipment in merch trailers, dragging stuff out, trying to make do. So when we rolled in with a complete gym, they were so excited.”

Marketing by experience
Rather than spending heavily on ads, Fit Truk focuses on getting people to step onto a truck and try it out.
“Our biggest marketing component right now is getting the truck out and letting people experience a workout on it,” Guffey said. “Once somebody goes through one workout on it, they’re like, ‘holy crap, that was fun.’”
He explained that the design makes the workouts approachable. Forty participants can train at once, each on a different station.
“Nobody notices if you can’t go as hard as the next person because everybody’s in the zone doing their own thing,” he said.
Bland Walsh sees these workouts fitting into a growing national trend. Social wellness events, she noted, are giving people a new way to meet, connect, and stay active.
“People are using these sorts of social wellness groups to build community, to build friendships,” she said.

Staying lean
Fit Truk operates with a small team. Alongside the co-founders are operations specialist Ashley Walker and a part-time West Coast representative. The founders have kept the company lean on purpose.
“We’ve been ruthless in our entrepreneurial strategy the last few years to be as lean as we possibly can in an effort to get ourselves to a place where when it was time to start doing a capital call, our business would be ready to scale,” Bland Walsh said.
That discipline, she believes, has set the stage for the company’s next phase.
“We feel like after three years of research and development, we are the best mobile fitness gym, outdoor gym experience in the world,” she said.

Accessible impact
Fit Truk’s trucks have also found a place with nonprofit and adaptive fitness organizations. One partnership will put the company’s original ambulance truck in the hands of the Adaptive Training Foundation in Texas, where it will be used to train veterans and people with disabilities.
“Our trucks are accessible in a wheelchair all the way around,” Guffey said. “It’s really cool to see our trucks being used in those ways.”
With record sales, a widening client base, and a product that is sparking interest in multiple industries, Fit Truk’s next stretch of road looks busy.
As Bland Walsh put it, “We want to change the face of the fitness industry. And in order to do that, you have to be really thoughtful and really focused.”
