The app has been created to be SIMPLE : it’s simple to set up your workout, it’s simple to use so you can forget about it during your training and just follow the sounds.
* WHAT’S HIIT ? *
High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is an enhanced form of interval training, an exercise strategy alternating periods of short intense anaerobic exercise with less-intense recovery periods. HIIT is a form of cardiovascular exercise. Usual HIIT sessions may vary from 4–30 minutes. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning.
This definition comes from wikipedia (http://en.wikipedia.org/wiki/High-intensity_interval_training) where you can find a lot more informations. It explains some very popular program, like the TABATA. HIIT is also a common practice in Crossfit trainings.
* HOW TO USE THE APP ? *
You can use it while cycling, running, sprinting, weightlifting, circuits, tabata….
On the first screen you will set up your workout : preparation time, work, rest, rounds and cool down
Then hit “Go !”, work and just follow the whistle !
You can listen to your own music, just make sure you can still hear the whistle.
See, it’s very simple !
