Do you have belly fat that won’t go away, no matter how much you exercise?

There truly is a secret to burning fat, and this fat-loss technique has been proven time and time again with scientific studies on maximum fat loss.

In order to blast ugly fat off your belly, you must kick up your human growth hormone: nature’s most powerful fat burner — but not with hormone injections or hormone pills.

It’s with high intensity interval training exercise, and only four minutes’ worth of effort, twice a week; that’s all that’s needed to burn belly fat like never before.

To get going on fat loss in your fat belly (or even fat thighs), make sure you have a great pair of hiking/running shoes, a cross between hiking boots and running shoes.

Go to the foothills (if you don’t live near any, keep reading) and find a short but steep trail. It can be all grass or man-made with rocks. A mad-dash up this trail should take around 30 seconds.

The fat burning workout begins with a warm-up, which consists of simply walking to this steep short trail from your car.

Your car should be parked within a five- to ten-minute walk of the trail. Walk briskly, then as you approach the foot of the trail, bolt into as fast a run as possible, all the way to the top of the trail.

Depending on fitness level, a person won’t actually be running. If the trail is full of rocks to step upon, a person may be slowed down even more if he or she lacks agility.

But don’t let this stop you from fighting it out as hard and as fast as possible, all the way to the top.

It should take 30 to 60 seconds to get to the top, depending on fitness level and coordination. But if it takes longer than 45 seconds, see if you can charge faster.

If you can reach the top in only 15 seconds, find a longer trail so that you are exhausting yourself for 30 seconds.

At the top, an individual should be so drained that he or she is forced to stoop over, hands on knees, and pant for several seconds.

After five or so deep pants, walk around casually on flat or downhill terrain for several minutes. Coordinate this recovery walk so that after 3-4 minutes, you’re at the beginning of the workout trail again.

Repeat…seven more times.

Each dash up the trail should take about 30 seconds. Eight of these sprints, times 30 seconds, equals four minutes.

The recovery walk in between isn’t much exercise, but is valuable because it allows your body to replenish energy for the next high-intensity interval up the steep grade.

An individual who is not forced to stoop over at the top of the hill after dashing up it, is not dashing fast enough.

And I must emphasize, re-evaluate your effort level if it’s taking you longer than 45 seconds.

The trail should be just the right length such that, at about your fastest charge, you’re pretty close to the top in about 30 seconds, give or take a few seconds.

This exercise technique is called high intensity interval training and will burn excess fat wherever it is, like never before, because it triggers increased production of human growth hormone.

Do this workout twice a week. If there are no hills near your house, apply this principle to flights of stairs in a building, and leap up the steps two at a time as fast as possible can until you’re ready to drop.
