How To Use The Interval Timer Effectively
The interval timer is ideal for HIIT, tabata, circuits, mobility drills, and classroom activity blocks. Configure work, rest, rounds, warmup, and cooldown to match your routine.
All settings are saved in browser storage, so your usual workout format is ready when you return. This makes the tool practical for repeat sessions on the same device.
