Exercising Pours Fuel into Your Body
It might sound strange, but it’s true that moving more can help give you more energy, through several mechanisms. To begin with, cellular-level changes occur inside your body when you exercise. Exertion spurs your body to produce more mitochondria inside your muscle cells. Mitochondria are known as the powerhouses of cells, because they create fuel out of glucose from the food you eat and oxygen from the air you breathe. Having more of them increases your body’s energy supply. Exercising also boosts oxygen circulation inside your body. This increase in oxygen not only supports the mitochondria’s energy production, it allows your body to function better and to use its energy more efficiently. Plus, your body gets a boost from an exercise-induced increase in hormone levels that makes you feel more energized.
