A coach in your pocket that adapts to how you actually feel
VO3 is an AI sports scientist that builds and adjusts your endurance + strength plan around your real recovery data — every single day. No generic templates. Just the right session for today.
Max reads your HRV, resting heart rate and sleep each morning and tunes today's session — push when you're primed, back off when you're not.
Built for hybrid athletes. One intelligent plan that balances running, riding, swimming and lifting so they complement each other instead of competing.
Ask Max anything — why a session changed, how to pace a race, whether to train through a niggle — and get answers grounded in your own data.
Send any planned workout to your Garmin or Wahoo in one tap via intervals.icu. Train with structured targets, no manual entry.
How it works
A 2-minute setup: your sports, schedule, event and starting fitness. Connect intervals.icu — it syncs your Garmin, Whoop, Strava and more — to bring in your history.
Max builds a periodised plan towards your goal — then reshapes it daily based on how recovered you are.
Do the session, push it to your device, log it automatically. Watch your fitness build on clear, jargon-free charts.
Why VO3 is different
Most plans are fixed PDFs. VO3 rewrites your week around your actual recovery and life — automatically.
Stop juggling a running app, a lifting app and a spreadsheet. Endurance and strength live in one coherent plan.
Max explains every change in plain language and answers your questions — so you learn, not just follow.
Encrypted credentials, no selling your data, and one-tap export or delete whenever you want.
