The HYROX Training App With AI Plans That Adapt to You
RoxDuo builds your entire block — from today to the start line — around your race, your level, and your weak stations. Built doubles-first, it works just as hard for singles athletes.

What RoxDuo actually does
The plan chain: complete today, unlock tomorrow
Most plans die in week 3 — not because the sessions are wrong, but because nothing holds you to them. In RoxDuo, tomorrow's session is locked until today's is done. Miss a day and the chain waits for you; it does not pile guilt or stack three sessions on Saturday. One day, done properly, then the next. That mechanic is the app's spine, and it came straight from training, not from a product meeting.
Why not a generic gym app?
A generic app can give you workouts. HYROX is not generic — it is a fixed race format with known distances, known station order, and a clock. The plan should know that too.
| What matters for HYROX | Generic gym app | RoxDuo |
|---|---|---|
| Plan endpoint | Open-ended program | Your race date — the plan tapers into it |
| Session content | Generic strength/cardio | The 8 stations plus compromised running |
| Progress metric | Weight lifted, streaks | Station PBs and projected finish time |
| Doubles support | None | Team Sheet: splits, swaps, projected finish |
| Consistency | Reminders | Unlock chain — complete today, unlock tomorrow |
Pricing, honestly
RoxDuo is €6.99/month with a 3-day free trial — enough time to see your full plan, log sessions, and decide. No lifetime deals, no locked "pro tier" surprises: one subscription, everything included. Cancel any time in your App Store settings. That is the whole pricing page.
Built and used by an athlete
RoxDuo is built by Filippo Terzi, who is training for HYROX Rome (September 2026) on the plan the app generates for him. If a session structure does not survive contact with a real training week, it does not ship.

FAQ
How does the RoxDuo AI training plan work?
You tell RoxDuo your race date, your current running and strength level, and how many days per week you can train. It builds every session from today to race day — runs, station work, and hybrid sessions — and tapers the load into race week. Log your results and the plan adapts as your station PBs move.
What is the plan chain?
Sessions unlock one day at a time: complete today's session and tomorrow's unlocks. You cannot cherry-pick the fun sessions from week 6 or silently skip sled work. It is a consistency mechanic — the plan you actually finish beats the perfect plan you abandon.
How much does RoxDuo cost, and is there a free trial?
RoxDuo costs €6.99 per month with a 3-day free trial. Everything is included during the trial. Cancel any time from your App Store subscription settings and you keep access until the period ends.
Is RoxDuo suitable for a first HYROX race?
Yes — the plan scales to your starting point, and the site has a full beginner guide plus station-by-station technique pages. If you can run-walk 5km today, there is a realistic path to a finish line.
Is RoxDuo on Android?
Not yet. RoxDuo is launching on iPhone first via the App Store.
