When it comes to burning calories, I can't imagine doing an excise routine other than HIIT for maximum results.
If you are looking for the exercise that burns the most calories, takes the least amount of time and launches you past all other cardio routines you've ever tried, then you have to give a HIIT workout a try.
HIIT, or high intensity interval training, takes traditional cardio to a new level of fat burning.
Until I started doing these types of workouts I used to think that this exercise burns the most calories: 45 minutes to an hour on a stationary bike or treadmill - I was wrong! Now that you know what exercise burns the most calories, here's how to preform your workout.
You can still use a stationary bike or a treadmill and increase the amount of calories you burn dramatically.
If you preform a routine where you pedal or walk at a slow to moderate pace for a short time period followed by a period where you give it 90-100% alternate you will honestly be amazed at the amount of calories you burn.
By exercising in these types of intervals you will literally burn your fat for fuel and the pounds will melt off.

One of the biggest advantages to doing this exercise routine to burn fat is that your body releases a substantial amount of HGH - human growth hormone and this is what is responsible for making your body burn fat.
Your body will be revved up and you will actually continue burning calories long after your workout is over.

Here is the breakdown of the exercise routine to burn fat:

• Walk for 1 minute
• Jog for 1 minute
• Walk for 1 minute
• Jog a little faster for 1 minute
• Walk for 1 minute
• Run for 1 minute

Continue to do this in a progressive manner until you are running at a rate that you can only hold for that 1 minute.
I would recommend doing this for 10-15 minutes the first few times and then you can progress to 20-30 minutes.
