Intelligence that works
in the background.

Watches your journey. Elevates without shouting.

Before

Kraft

Tells you what to do next. AI-generated workouts tailored to your history, your level, your goals.

After

Feedback

Tells you how you did. Insights after every workout. What worked. What to adjust. What you couldn't see yourself.

Weekly

Chronicle

Tells you who you're becoming. Your weekly training story - written by an AI that remembers every rep, every week, every breakthrough.

That's not three features. That's a witness to your grind.

Bring your own AI.

Your log is yours. Your AI can read it too.

“Claude, look at my week and set up Thursday's push workout.”

Your AI reads your grind: every workout, every set, the feedback you got. Thursday's workout is waiting in the app when you step up to the bar.

Works with Claude and ChatGPT. It can read and write, but never edit what's already yours. Part of XTA Apex.

"Your Grind. Witnessed."

Built by athletes
who got tired of the noise.

We've been training calisthenics for years. We've tried every app. They all did the same thing - sell us programs, cram the screen with videos we didn't need, gamify our training into badges and streaks.

We didn't want motivation. We didn't want content. We wanted a clean app to do our work. And an AI smart enough to see what we couldn't.

So we built XTA. Not as a side project. As the app we wished existed.

We're data scientists and engineers by trade. We've spent a decade building AI systems at scale. XTA isn't a fitness app with AI bolted on. It's an AI system built by people who understand both the data and the grind.

We use XTA every morning. Every feature exists because we needed it. The Chronicle? It started because we wanted something that remembered our journey. Kraft? Because we got tired of programming our own workouts.

The science behind
every rep.

Free. Public. No account, no paywall.

Real footage of correct mechanics: where the load goes, which muscles work, how the body fights gravity.
