HIIT Timer
High-intensity intervals need a clock you do not have to look at. Set the session and work to the alarm.

What this one is for
- Hard efforts, honest rest
- Warm up before the first round
- Big digits from the floor
High intensity means the effort must be genuinely hard, not merely brisk. If you could comfortably continue past thirty minutes, it was a moderate session wearing the wrong name. It opens at 20:00; change that with the chips under the dial.
Worth knowing
- If you could comfortably keep going past thirty minutes, it was not HIIT.
- Warm up first; the first interval should not be the warm-up.
- Fifteen to twenty-five minutes including the warm-up is a full session.
Getting the most from the hiit timer
- Warm up before the clock mattersTwo or three minutes of easy movement first. The block is for working, not for getting ready to work.
- Set the effort, not the distanceTime-based work holds up on a tired day because the finish line does not move.
- Come down slowlyWalk or breathe it out for the last minute rather than stopping dead when the alarm goes.
