Warm up first, choose safe intervals, and stop if you feel pain, dizziness, or unwell. Timer sounds depend on your device settings.
How to use interval training
Set a work interval, a recovery interval, and the number of rounds. Start with an intensity and duration that match your fitness level, and increase gradually as appropriate.
Build a repeatable routine
Use the same interval structure for circuits, bodyweight exercises, stretching, or cardio. Take additional rest whenever you need it; the timer is a guide, not a requirement to push through discomfort.
