When you walk into Infinite Fitness, you won’t find a sea of machines, rows of treadmills, or a swarm of earbuds and protein shakers. You also won’t find any judgment. Or contracts you regret signing three weeks later. What you will find? A radically human approach to fitness, especially for those of us who’ve graduated past the “max out your deadlift” phase of life.
I had the pleasure of interviewing Jonas Acevedo, founder of Infinite Fitness and one of the newest business owners to join the Round Rock community. His approach to fitness is refreshing, deeply personal, and laser-focused on the people most gyms ignore: adults over 40.
Why Round Rock? Why Now?
Jonas did his homework. After scouting several locations, he landed on Round Rock because of the culture, the community, and the people. It wasn’t just real estate. It was resonance. And when your mission is to serve a specific group with care and intentionality, vibe matters.
Not Just Workouts. Wins You Can Feel.
What sets Infinite apart isn’t the equipment. Jonas will be the first to tell you most gyms probably have more gear. But gear isn’t the game-changer. It’s how you use it.
Infinite’s model is small group personal training for adults 40 and up, often beginners, often with past injuries, often feeling unwelcome in typical gym environments. The focus? Functional movement. Not for Instagram, but for real life. Picking up grandkids without throwing your back out. Throwing mulch over the fence without needing an ice pack. That kind of strong.
It Starts with a Conversation
Before anyone touches a kettlebell, Infinite Fitness starts with a simple call. “Are we the right fit for each other?” Jonas isn’t trying to sign you up. He’s trying to understand you, your goals, your obstacles, your story. From there, an in-person consultation maps out the right path, whether it leads to Infinite or somewhere else.
The Anti-Planet Fitness
Here’s something rare: Infinite caps their membership around 150 people per location. It’s not a numbers game. It’s a results game. If you stop showing up, they check in. If you’re plateauing, they notice. If you’re struggling, they adjust. That’s not a gym membership. That’s a relationship.
Built on Real Stories, Not Hype
Jonas didn’t set out to train people over 40. Like most trainers, he thought athletes were the dream. But then he watched his own mother stay active into her 70s, walking 14 miles a day in NYC while he struggled to keep up. He realized the “sexy” part of fitness wasn’t youth. It was vitality. And it’s infectious.
Now, Infinite serves clients well into their 80s and 90s. People who never thought they’d squat again are lifting grocery bags with ease. Grandparents are chasing toddlers without pain. And while nobody’s setting deadlift PRs, they’re setting records where it counts, in life.

Rock Solid Podcast – Bryan Eisenberg with Jonas Acevedo of Infinite Fitness
Bryan Eisenberg:
Welcome to Rock Solid: Round Rock Business Leaders. I’m Bryan Eisenberg, and today I’m with my friend Jonas Acevedo, founder of Infinite Fitness. Jonas, thanks for joining me.
Jonas Acevedo:
Thanks for having me on.
Bryan:
I was at your ribbon‑cutting with the Round Rock Chamber a few weeks ago. Tell us why you chose Round Rock for the new studio, then we’ll talk about your other location.
Jonas:
We scouted a few real‑estate spots, but Round Rock’s vibe, culture, and sense of community felt right for the people we serve. The area really matches our 40‑plus training focus.
Why Serve the 40‑Plus Crowd?
Bryan:
Your model is unique. It’s a coaching studio, not an open‑gym setup, and you specialize in clients over 40. Why that demographic, and how is training them different?
Jonas:
Most trainers dream of working with athletes. I did, too. Then I saw the need among adults 40 and up. In the next decade there will be more people over 65 than under 18. Strength training makes a huge impact on their health span.
On a personal note, my mom is in her mid‑70s and still active. She hiked 14 miles with me in New York last year. Seeing her quality of life convinced me this market matters.
Typical Client Experience
Bryan:
At your Shoal Creek location you’ve trained for years. Are most new clients gym veterans or absolute beginners?
Jonas:
A lot are beginners, many with prior injuries. We’re one of the few places explicitly built for 40‑plus, so we designed everything—programming, staff training, even the environment—to reduce intimidation.
Functional Fitness Over Bench‑Press Bragging Rights
Bryan:
You emphasize functional fitness: lifting suitcases into overhead bins, playing with grandkids, that sort of thing. Why does that trump the classic bench‑press routine?
Jonas:
It doesn’t matter how much you bench if you tweak your back picking up your kid. Our best wins are clients saying, “I tossed mulch over the fence for the first time.” We train skills that show up in real life, not just on the gym floor.
The Infinite Fitness Onboarding Process
Bryan:
Walk me through a first‑time client journey.
Jonas:
- Phone call. We check fit on both sides and calm any nerves.
- In‑person success session. We map goals, current abilities, and obstacles.
- Personalized roadmap. That might be small‑group training with us or, if needed, a referral to physical therapy. Clients get a clear path, not a sales script.
Capping Membership for Community
Bryan:
You cap each studio at about 150 members. Why limit growth?
Jonas:
Our success depends on clients using the services, not skipping them. A smaller roster lets us notice when someone stops showing up and reach out. It keeps culture strong and coaching personal.
Finding the Right First Step
Bryan:
If someone over 40 in Round Rock wants to improve health but isn’t sure whether to hire a trainer or join a gym, what’s step one?
Jonas:
Assess your support needs. Even gym owners like me need accountability. Research places aligned with your goals and values, then try a conversation first.
From Heavy Lifts to Lighter Living
Bryan:
For the record, what was your heaviest deadlift?
Jonas:
About 550 lbs, but those days are behind me. Heavy numbers aren’t required for lifelong health.
Entrepreneurial Journey
Bryan:
You graduated in kinesiology at Texas Tech, moved to Austin, and opened several ventures before Infinite Fitness. Give us the quick tour.
Jonas:
I helped my mentor Coach Mo open a gym, tried online coaching, ran “Recovery Fitness” for treatment centers, then a corporate‑wellness boot camp. In 2018 Infinite Fitness launched. We refined it to small‑group personal training in 2023 and now plan more focused locations.
Studio Design Philosophy
Bryan:
Your studio feels open and uncluttered—very un‑gym‑like. What drives that design?
Jonas:
We care more about who we train than how many gadgets we own. Basics done well—proper movement, progressive strength, pain‑free mechanics—beat the latest flashy equipment.
Community Partnerships
Bryan:
At the ribbon cutting you’d partnered with Clean Eatz and Blue Lotus. What do ideal partnerships look like?
Jonas:
Shared demographic, shared values, growth mindset. Partnerships can be workshops, events, staff training swaps, or simple referrals.
Success Stories
Bryan:
Oldest client?
Jonas:
Ninety‑one or ninety‑two at Shoal Creek. Consistency is the magic. One couple, Shel and Mitch, have trained with us for years and still bike and walk with me regularly. The big wins are playing with grandkids, traveling pain‑free, living life fully.
