The whole idea
20:00
Locked. Every workout. Every day.
-
Exactly twenty minutes
Long enough to count, short enough to keep. The clock is the brand — nothing runs over, nothing runs short.
-
Guided, not just timed
A guided timer counts you down, cues every movement, tracks your rounds and rest, and advances itself. You just move.
-
Bodyweight to barbell
Tell it what you’ve got and it scales the work — or grab a famous benchmark and chase the standard.
-
No fluff
No social feed, no streak guilt, no 45-minute warm-ups. Press play, move, done. Then get on with your day.
Four ways to train
Real formats, run for real.
Not a list of moves on a page. Each format drives a purpose-built timer that knows how to count it.
EMOM
Every minute, on the minute. Finish the work fast — the leftover seconds are your rest.
Rounds / AMRAP
One set, repeated as many rounds as possible until the clock runs out.
Timed Blocks
AMRAP windows with mandated rest between them. Benchmark-grade conditioning.
The library
A library that keeps growing.
Hand-curated heroes and famous benchmarks — Cindy, The Chief, Mary, Tabata Something Else — plus a builder that makes a fresh session from your goal, your gear and your intensity.

FAQ
Good questions.
Do I need equipment?
No. Plenty of workouts are pure bodyweight. If you’ve got kettlebells, dumbbells, a barbell or a band, TWENTY scales the work to match what you tell it you have.
Why exactly 20 minutes?
Long enough for a real training effect, short enough to actually do every day. The constraint is the point — every workout is built to fill exactly 20:00, no warm-up padding, no cool-down filler.
Is it actually guided?
Yes. A countdown timer cues each movement, counts your rounds, handles the rest periods, and tells you the moment you’re done. No spreadsheet, no guessing what’s next.
What does it cost?
Two workouts are free forever — no card needed. Pro unlocks the full, growing library for $49.99 / year or $9.99 / month.
Is TWENTY available now?
Yes — TWENTY is out now on the App Store for iPhone and iPad. It’s a free download: start with two workouts, no account or card required, then unlock the full library with TWENTY Pro whenever you’re ready.
