Questions
How long is a heavy bag round?
Three minutes with a minute of rest, matching a boxing round.
What does the ten-second warning do?
The clock turns yellow and a clapper sounds ten seconds out, so you can finish hard without watching the screen.
How many rounds should I do?
Whatever the session is built for. The timer runs rounds back to back until you stop it.

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 →
