11 things about HIIT 4x4

1. HIIT 4x4 is based on the High Intensity Interval Training 4x4 program developed by the Norwegian University of Science and Technology's Cardiac Exercise Group.

2. The intensity of the exercise is measured as a percentage of a person's Maximum Heart Rate (MHR).

3. A more accurate number can be discovered by using a heart monitor during all out exercise and observing the highest heart rate achieved.

4. HIIT 4x4 is an Apple Watch exercise monitoring app for High Intensity Interval Training (HIIT).

5. HIIT 4x4 uses a speedometer type dial to display heart rate.

6. When the arrow is in the green zone then your heart rate is within the interval target.

7. If the heart rate later falls out of the target range, warning chimes are issued until back in range.

8. The app sequences exercise between high and low intensity intervals.

9. - repeat high-low intervals 4 times (4 high intensity intervals of 4 minutes each = 4x4).
