Theres a saying, Use it or lose it. Thats pretty much why exercise is good for you. But thats just the short answer. The details of what actually happens in your body are truly amazing and, I think, super motivating. Heres the the rest of the story you wont want to miss!

[This article is going to motivate you to exercise more. So here's the obligatory, but important, cautionary note. If you are going to start an exercise program, you should have the OK from your doctor first to make sure that you don't have any potential heart or other health issues.]

The very first day that you start your exercise program, you will be healthier than you were yesterday. Why? Because your body immediately responds to the exercise by building new cells and tissues to support that exercise. It gets ready to better handle the exercise you will do tomorrow. Isnt that amazing!?

There are several marvelous ways that your body changes when you begin a consistent aerobic exercise program. All of the improvements your body makes increases your VO2 Max, which is a measurement of of your fitness level. Specifically, VO2 Max measures the volume of oxygen a person can consume in one minute exercising at maximum exertion.

Here are the incredible changes youll see in your body:

When you train over a period of time your heart will grow in size, allowing it to pump a larger volume of blood with each stroke (or pump). This allows more oxygen to be delivered to all the cells in your body. At the same time, your heart also becomes stronger and more efficient at pumping blood.

In response to your muscles needing more oxygen, your body will grow more capillaries to deliver more oxygen faster going forward. Isnt that cool?! In addition, over time, regular exercise will make your blood vessels become more flexible allowing them to deliver more oxygen rich blood more efficiently. And if that wasnt enough, the increased blood flow in your blood vessels serves to clean out excess cholesterol, keeping you free of clogs which can cause strokes and heart attacks.

As you exercise each day, your body says, OK, I get it. You need more oxygen. Alright, turn up the red blood cell production! As your red blood cell count increases so does your ability to receive more oxygen more efficiently.

This improvement is very cool too. In each of the cells in your body there are these little power machines called mitochondria. What they do is produce energy by combining oxygen and glucose (or other fuel molecules). This combination produces ATP which is the molecule that gives your cells the energy they need to do their cellular work. When you exercise regularly, guess what happens? Yup, your body creates more and stronger mitochondria in each of your cells, making you more powerful and giving you more endurance for everything in your life! Wow! How exciting is that!?
