Perhaps the most common type of exercise is aerobic exercise, also called cardiovascular exercise, which utilizes oxygen and helps burns fat. This type of exercise has consistently shown in numerous studies to improve cardiovascular and respiratory health. This means that as a result, this type of exercise conditions the lungs to be able to use more oxygen while increasing your heart's efficiency by decreasing heart rate.
What's this mean to you?
After conditioning this aerobic pathway through cardiovascular or aerobic exercise you will be able to more effectively burn fat. The harder you exercise aerobically; your body switches to burning more glycogen as its main fuel, from fat. Glycogen is stored carbohydrate and is limited in supply. As a result you become fatigued relatively early and are unlikely to continue.
However after regular aerobic exercise, your ability to burn fat even at higher workloads increases compared to when you were not training. Basically, the point at which your body switches from burning fat to glycogen will be raised. So through this type of exercise, you will be able to exercise harder with less effort and your main source of fuel will be stored bodyfat. That has to be great news, right?
In order to condition this cardiovascular pathway and reap its many benefits, we must increase our heart rate and keep it elevated for at least 25 minutes, 3 or more times per week.
A brisk walk or jog on your treadmill should be enough to gain the many health benefits. But as with every exercise program that is geared for results, improvements and personal bests we must practice PROGRESSION.
