If you want to get the most out of your treadmill and lose weight fast, you should consider HIIT, which stands for High Intensity Interval Training. Many people are doing HIIT because it takes less workout time and they lose weight faster. People stick to HIIT because it is a fun way to workout and routines can be varied from workout to workout.

HIIT really became popular for treadmill owners when a study came out about a decade ago. The study involved test subjects who were put on exercise programs for five months. The subjects were put into two groups. The first group did steady pace cardio for 45 minutes. They started out at 60% of their maximum heart rate and by the time the study was over they were working out to 85% of their maximum heart rate.

The second group did HIIT for 30 minutes. Their workouts consisted of bringing their heart rates up to 70% of their maximum heart rates. Then for ten seconds they would back down on their workout intensity so their heart rates would fall. The group then did a 90 second period of working out that brought their heart rates back up again. Afterwards, they went back down into a lower intense workout so their heart rates would slow down, again. This was repeated throughout their 30 minute workout.

After the study was done experts concluded that the second group that had been doing HIIT used less energy and time working out during the five months. It was also found that the second group lost three times more fat than the other group, and the fat group two lost was primarily the fat that many people find so hard to get rid of, subcutaneous fat, or the fat that is directly beneath the skin.

What makes HIIT so great for weight loss is your body goes into EPOC, or Excess Post-exercise Oxygen Consumption. In a nutshell, your body requires more oxygen to get back to its resting state which means you continue to burn calories even hours after you have completed a HIIT routine. In fact, a 2002 study showed the resting metabolic rate of participants was still elevated 48 hours later. This is great news for someone who wants to lose weight and get their metabolism boosted.

Treadmill owners love doing HIIT because it works for so many of them. The added bonus is doing HIIT on a treadmill lets people have a fun workout quickly. HIIT routines are intense, but they should last no more than 20 to 30 minutes. Start your workout warming up to your maximum heart rate range, then cycle in and out of lower heart rate zones and then raise your heart rate back up to it maximum rate, again. Repeat this throughout your workout doing as many, or as few, intervals as you like.

While HIIT is a very popular way to lose weight fast with treadmills, keep in mind that it is not recommend that you do HIIT more than two or three days a week. HIIT works and it does put your body under stress. You shouldn't do HIIT day after day. But, don't feel like you are cheating. Your body is still burning fat and calories long after your workout is over!
