Use a full routine with exercises, timing and rests.
GD-02 / Start here
Use a timer that can repeat a sequence of work and rest periods. Decide the exercise, work duration, rest duration and number of rounds before you start.
The idea
HIIT is a training approach that commonly uses harder work periods and recovery. The timer handles the transitions; it does not decide how hard you should exercise.
A useful plan names the movements and accounts for warm-up, rests and the final interval. Two routines with the same 40/20 timing can feel very different depending on the exercises and effort.
A practical example
The linked workout lists every movement and rest so you can follow it manually. Choose lower-impact versions when you want a gentler session.
Keep in mind
A timer cannot judge exercise technique, fatigue or whether an intensity suits you. Adjust the movement or pace as needed.
