How does exercise boost energy levels?
In: Biology
Your body will adjust almost everything based on your circumstances.
If you lift heavy things, your body will add muscle wherever you used it so that next time you are better able to lift things.
If you run or jump or lift heavy enough things it will stress your bones, so your body will strengthen them so that next time you are less likely to break them.
If you run up steep hills a lot at high altitude in the heat, your body will add red blood cells to your blood, add muscle to your heart, add space to your heart, add muscle to your legs, increase how much sweat your skin can make, add blood vessles to your legs, add calcium to the bones in your legs, increase how well your liver produces glycogen, and make your legs better at using glycogen so that next time it’s easier.
The thing is, your body assumes anything you do a lot is normal, so be ready for that thing.
Exercise means your body gets ready for more exercise. If you exercise enough then your body is ready for exercise all the time.
If you are ready for exercise, but not exercising, then sitting around will feel easy. This feels like having more energy.
