ABOUT REXUM
Make intelligent, adaptive training available to anyone — regardless of their equipment, their gym membership, or their budget.
Most fitness apps are built around the gym. They assume barbells, squat racks, cable machines. If you train at home or outside, you adapt to the app — not the other way around. The result is programs that don't fit your life, built with equipment you don't have, that stop working after week two.
Who it's built for
If you can't — or won't — train in a gym, this is for you.
A spare room, a living room floor, a set of dumbbells. You have enough. The AI builds around what you actually have.
Parks, trails, open space. No weights needed. Programs that treat outdoor training as a first-class option, not an afterthought.
No experience needed. The AI starts where you are, not where it assumes you should be. Progression happens automatically.
No jumps, no noise, no equipment. Programs that respect your space and your neighbors.
Hotel room, rooftop, whatever you have. The program adapts each week to wherever you are.
Already know what you're doing. Rexum just handles the programming — real progressive overload, not random daily workouts.
Founding story
The why.
Rexum started with a frustrating realization: every fitness app on the market assumes you have a gym. Pull-ups assume a bar. Bench press assumes a bench. HIIT programs tell you to sprint — without asking whether you have space to sprint.
The founder had been training at home for three years. Not because it was fashionable, but because it was practical. And every time a new app came out promising "personalized" programs, it lasted about two weeks before the disconnect became too obvious to ignore.
The fix wasn't a better template. It was an AI that actually started by understanding your situation — your equipment, your space, your goals — and built from there. Then kept adapting as you logged results week over week.
That's what Rexum is. No gym required. No assumptions. Just a program that fits.
“Every app told me to adapt to it. I wanted one that adapted to me.”
What makes it different
The gap it fills.
Most fitness apps are content libraries. Rexum is a training system. Here's what's different.
YOUR PROGRAM IS ONE MINUTE AWAY.
No gym required. No equipment assumptions. Free forever. Tell the AI what you have and where you train — it takes care of the rest.
