HIIT | Training for Fast, Efficient Fat Loss


Many of you have asked me what exactly is HIIT and how it works.

HIIT is referred to High Intensity Interval Training.
This means fitness training is performed in timed high intensity intervals followed by timed active recovery intervals. For example, you can perform high intensity training at 90% of your **VO2max for 4 minutes followed by light or moderate interval such as cycling for 2 minutes. This would be performed for 8-10 rounds making the HIIT portion of the workout – 35 minutes.

“VO2max is the metric that defines your personal fitness level, cardiorespiratory/aerobic capacity. It describes your body’s ability to bring oxygen into your body through your lungs, transport it through your blood supply to your muscles, and use it as part of your body’s most efficient energy production method.”

It is the measurement of the maximum amount of oxygen that an individual can utilize during intense, or maximal exercise. It is measured as milliliters of oxygen used in one minute per kilogram of body weight (ml/kg/min). It is one factor that may help determine an athlete’s capacity to perform sustained exercise.

Two of the main reasons HIIT style workouts have become popular is that the length of time you exercise is less and the increases in fat burning is greater.

There are many studies that have been conducted with the effects of HIIT training in obesity as well as people who participate in consistent moderate intensity exercise.

The outcomes of HIIT reduce abdominal and total body fat in much less time than steady state exercise. Also, in as little as 6 workouts over a few week period, HIIT has increased fat-burning capacity in a faster time.
