About Passo

What is Passo?

Passo is a free bodyweight workout generator built around the philosophy of progressive calisthenics — the idea that anyone can build real strength using nothing but their own body, as long as they take the right next step.

No gym membership. No equipment. Just you, a plan, and consistent progress.

The Philosophy

Most fitness apps overwhelm you with choices. Passo does the opposite — it gives you exactly the right workout for your time and level, then automatically scales with you as you improve.

• →Start anywhere — beginner to advanced
• →Progress is built in — every exercise leads to the next
• →Short sessions count — even 10 minutes builds the habit
• →No guesswork — science-backed progression rules

How It Works

1. 1Tell Passo how much time you have and your fitness level.
2. 2Get a structured workout: warm-up, main exercises, cooldown.
3. 3Do the workout with guided timers and rep tracking.
4. 4Submit feedback (effort level + any pain). Passo remembers.
5. 5As you improve, your next workout automatically levels up.

Built by Diego Alducin

Passo is a personal project by Diego Alducin, a developer and calisthenics enthusiast. It was built to scratch an itch: a workout app that doesn't need a subscription, works on any device, and actually gets smarter as you train.

Tech stack: Python + FastAPI (backend), Next.js + React + TypeScript (frontend), SQLite, deployed on Railway and Vercel.
