Measure your cycling FTP on your smart trainer, in your browser. Twenty-one minutes, no account needed, and your power zones leave with you.
Pair your trainer over Bluetooth, straight from the browser. Heart rate is optional.
The resistance climbs in small steps until you cannot hold it. That is the whole test.
FTP plus all seven training zones, on screen and in a file that is yours to keep.
No sign-up. Runs in Chrome or Edge, on the trainer you already own. Not sure your setup works? Check your Bluetooth first
Your seven zones, in watts — the number every structured training plan is built on.
Functional Threshold Power — the highest power you could hold for about an hour, in watts. It anchors every training zone and every interval target, which is why it is the first number any structured plan asks for.
The test and the download are free, no account asked. A free account is where the result starts working for you: your FTP is saved to your profile, every workout in the catalog scales itself to your zones, your rides back up automatically, and your progress page charts each new test against the last one. The test tells you a number — the account is what turns it into training.
A smart trainer that speaks Bluetooth FTMS, a bike on it, and Chrome or Edge. That is the entire list — and the Bluetooth check above will confirm your setup in under a minute.
