Detailed explanation-1: -Regular physical activity can improve your muscle strength and boost your endurance. Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.
Detailed explanation-2: -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.
Detailed explanation-3: -The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.
