What Happens to Your Body When You Start Exercising?

By rjoachim | September 28, 2022
Your body may need up to 15 times more oxygen when you exercise, so you start to breathe faster and heavier. Your breathing rate will increase until the muscles surrounding the lungs just can’t move any faster. This maximum capacity of oxygen use is called VO max. The higher the VO max, the more fit a person is.When you exercise, heart rate increases to circulate more oxygen (via the blood) at a quicker pace. The more you exercise, the more efficient the heart becomes at this process, so you can work out harder and longer. Eventually, this lowers resting heart rate in fit people.
