HIIT Field

A simple but useful High Intensity Interval Training timer.

HIIT Field” is a simple but useful High Intensity Interval Training timer.

Workout structure

A HIIT workout comprises a sequence of cycles composed of base cycles followed by a warm up and a cool down phase. Each base cycle is composed to a high insensitivity effort period followed by a moderate effort period. At the end of the base cycles, a rest is scheduled. A cycle is composed to the base cycles followed by the rest time.

The configuration for biking and running activities is separated to all others to enable a different setting for triathletes using a same data field.


  1. 10 minutes warmup
  2. 4 tabata runs ( 20 high effort followed by 10 second moderate effort. Repeated 8 times. At the end a pause of 1 minute)
  3. 2 minutes cool down.

The configuration would be:

  • Warm up duration (seconds) = 600 (10 minutes)
  • Main cycle: iterations = 4
  • Base cycle: iterations = 8
  • Base cycle: high effort duration = 20
  • Base cycle: low effort duration = 10
  • Main cycle: pause duration = 60 (1 minute)
  • Cool down duration (seconds): 120 (2 minutes)


The timer is implemented as data field1. It can be added to any activity. The start of each phase is announced by an acoustic signal, a vibration sequence, a data field alert, and by switching the back-light on. 3 seconds before each phase change a sequence of vibrations permits to announce it. The background colors of the field permits also to quickly see the current phase.
