Strength for the back half.
For the operator, the founder, the retiree: for the people who spent forty years building something, and now want a body that makes the next twenty worth it.
Training that comes to your door.
The best hour of your week, wherever home is. Programming written for your body, your goals, and everything you're about to do with the next twenty years.
The roster is accomplished professionals and retirees: bankers, post-exit founders, surgeons, attorneys, their spouses. People who bring the same standard to their health that built everything else in their life.
Long engagements. Written programming. One-on-one, every single session.
This is what strong looks like at seventy-one.
Strong at seventy-one isn't luck. It's programming, written down, year over year, built around everything a body can still do and then some.
Ten more years of trips, grandkids, first-tracks mornings. That's the project. This is what it looks like when you train for it.
Built for people who expect the best.
Seventy-one, and just getting started.
She spent a long career in marketing, and like most careers, it kept her at a desk. The years were full. The body waited.
After her husband passed, something shifted. Her health stopped being the thing she'd get to later and became the thing she was going to own. Then a round of concerning medical results made it urgent, and she started training with Justin: cardio and strength, twice a week, built for the body she has now and the results her doctor was watching.
Six months later, her cholesterol is down. The weight is coming off. And the word she reaches for is not thinner or fitter. It's energized.
"I am a 71-year-old woman who started cardio and strength training with Justin about 6 months ago after getting some concerning medical results. Since then I have lowered my cholesterol, lost weight and just generally feel more energized and strong. I recommend him highly."

One client at a time. In your home.
Justin comes to you: your living room, your garage, your building's gym. The equipment travels with him, the program is built around your space, and the best gym in Denver becomes the one inside your front door.
Your coffee. Your music. Your schedule. The hour slides into your morning like it was always there. And when you travel, the program travels with you, first class.

I started training because I wanted to be happier and to feel in control of my own health. That's the honest version, and it's still the reason.
Ten years in, almost every client on my roster is over fifty-five, and the work has taught me everything I didn't know at the start. I care more now about the sixty-three-year-old who can still get on the floor with his grandkids than any physique result I ever chased for myself. The training that gets someone there is patient, precise, and built to last.
This is a service that comes to you, in homes across Denver. I keep the roster deliberately small: fewer clients, longer engagements, real relationships.
