Most of people who work in a cardio program do seven, ten or more hours per week, and still have fat in their waist to burn for a long time. But there are other people who look great with the same or with even a smaller lapse of time. Some researchers in Great Britain went insight into this paradox, and studied 35 overweight men and women, who weren't previously exercising.

The subjects exercised for 12 weeks, 5 times per week. That's a lot of exercise and it helped the subjects lose an average of 8.2 pounds, but it worked better in young men, who need the help the least!

Back to the study, the variance in fat loss between individuals was huge. Check this out...The best subject lost a staggering 32.3 pounds in 12 weeks, while the worst subject actually GAINED 3.74 pounds.

The scientists think they know where things went sour. They classified the subjects into 2 groups, called the "Compensators" and the "Non-compensators". The Compensators were hungrier, and as a result consumed an extra 268 calories per day, all but wiping out their cardio efforts. Therefore, the Compensators lost the least amount of weight, and scientists believe that was due to the huge "compensatory" increase in appetite experienced by this group.

Does your appetite increase when you do slow cardio? If it does, research shows it will ruin your cardio efforts. So if your cardio program is not working for you, check your appetite and calorie intake to see if you are "compensating" for your efforts. If you are, you might be better off using a program of high-intensity resistance and interval training (i.e. Turbulence Training) for your weight loss efforts.

The research of a professor in Australia (Professor Steve Boucher) has show that interval training increases hormones called catecholamines. If that hormone increases, causes fat-burning benefits like reducing appetite, among others.

The most of people will rarely be in the very small group of people who lose 33 pounds after 12 weeks of cardio. To be realist, there isn't a lot of people who can achieve to loss 8 pounds in that lapse of time with aerobic exercise.

So again, check your appetite, and consider giving high-intensity exercise a go for your next workout program. Beat the curse of cardio with high-intensity Turbulence Training.
