High-intensity interval training, or HIIT, makes it easy to squeeze in fitness even when you’re short on time. If you only have 7 minutes HIIT can make it pay off and this app provides all you need to get moving, sweating and feeling fit.

This interval timer is designed for any kind of interval training. Our timer is easy to use and completely customizable. The circuit training timer will run through a series of exercises for a given number of sets. Optionally, you can provide rest between intervals, rest between sets, a warmup and a cooldown period by including a duration.

HIIT is a broad term for workouts that involve short periods of intense exercise alternated with recovery periods.
One of the biggest advantages of HIIT is that you can get maximal health benefits in minimal time. We added six workouts and another six '30-day' workout programs to quickly burn fat, lose weight or just getting into shape.

Interestingly, HIIT is perhaps the most time-efficient way to exercise.
Normally a High Intensity Interval Training will range from 7 to 30 minutes in duration. But despite how short the workout is, it can produce health benefits similar to twice as much moderate-intensity exercise.

The actual activity being performed is body weight exercises. It's probably the best workout type to do at home.
When done right, HIIT is your saving cardio grace. A good HIIT workout can deliver a lot of what you want from traditional cardio — burning fat, elevating your heart rate, pushing you to sweat, and improving lung capacity. All this in a fraction of the time, making it especially useful for those of us who can't spend all day in the gym and want to exercise at home.
