Questions

What is a good HIIT interval?

Forty seconds of work to twenty of rest is the most common in class settings; a minute each way suits heavier stations.

Can a whole class rotate off it?

That is what the rest period is for — the room moves to the next station while the clock counts it down.

Does it need an app or an account?

Neither. It runs in a browser and it is free.

Ask your coach to put this on the gym TV. It is free, it works on anything with a browser, and it runs on its own once it is up.

Gyms that want their own name, logo and colors on it instead of ours pay $99 once — no subscription, no per-screen fee. How that works →
