How can you tell if your heart is more fit as a result of an exercise program?

Improved resting heart rate. As your heart becomes stronger, it pumps more blood with each beat. This is known as the resting heart rate. A lower resting heart rate is typically a sign of a healthy heart.

Improved blood pressure. A regular exercise program can help to lower blood pressure in those with high blood pressure.

Increased oxygen consumption. A more fit heart is more efficient at delivering oxygen to the body. This can be measured through various tests, such as a VO2 max test.

Increased strength and endurance. A more fit heart is able to pump more blood and oxygen to the muscles for longer periods. This can result in increased strength and endurance during exercise.

Improved recovery time. A more fit heart is able to recover more quickly from exercise. This is because the heart is better able to deliver oxygen and nutrients to the muscles.

Increased stroke volume. As the heart becomes more fit, it is able to pump more blood with each beat. This is called the stroke volume.

Decreased heart size. A more fit heart is smaller than a less fit heart. This is because the heart muscle is more efficient and does not need to be as large to do the same amount of work.

Reduced risk of heart disease. A regular exercise program can reduce your risk of heart disease by improving your heart health.
