High Intensity Interval Training is the most intensive and extreme form of training we know of right now. Doctors have studied the results of regular HIIT training and they are astounded at the results because HIIT exercises are at least 10 times more effective in burning fat than regular exercises.
This is a proven fact and if you are here to find out how to take advantage of HIIT to improve your health and fitness, then you should definitely consider a HIIT treadmill workout as a starter for your entire workout routine.
How You Can HIIT a Treadmill
The idea behind HIIT is to alternate between low and high intensity workout styles in specific intervals of time. Thus, it is important to keep track of time as well. You should begin your exercise at the normal inclination and at a speed you are comfortable with to warm up.
Now, set a timer in the treadmill so that the speed will be increased to at least twice your speed after 23 minutes. Run at the increased speed for about 2 minutes. Now reduce the speed to a little more than your original speed. You have to alternate like this for about 78 times or around 20 minutes.
