High Intensity Session for Fat burning

To burn maximum amounts of fat, you should train in the 68 to 79% MHR window, this is the result from all this research. The reality is that if you train at higher intensities you can burn just as much fat.

• If you cycled along at 50% VO2max, fat would provide about 50%, on average, of the energy you needed to keep going.
• If you cycle along at 75% VO2max, fat would provide 33% of the required calories.

A moderately fit athlete exercising at 50% VO2max generally consumes about 220 calories during a 30 minute workout. If the same athlete want to burn 330 calories during the same period then he has to work out at 75% VO2max. Of course, 50% of 220 calories and 33% of 330 calories yield an identical number of calories coming from fat - 110 calories.

Fat provides all your energy. If fat alone was meeting all your body energy needs, you would not be breaking down carbohydrate during your workouts and as a result your leg muscles would be amply and permanently stocked with glycogen (assuming, of course, that your diet contained a normal carbohydrate content).Whenever you eat carbohydrate those will be processed and comsumed by your muscles. If your muscles were already full with carbohydrates, extra carbohydrate intake will be refused by your muscles and those surplus carbohydrate will then converted in fat.
