10.4 Preventing the Horsemen
One of the most effective ways to combat chronic disease, improve daily function, and enhance quality of life is regular physical activity. It benefits every system in the body, making it a cornerstone of long-term health and well-being. The scientific evidence supporting its widespread benefits is extensive. To quote Edward Stanley, the 14th Earl of Derby in Great Britain:
“Those who do not find time for exercise will have to make time for illness”.
Activity vs Exercise vs Fitness
Physical Activity
Physical activity includes any movement, spontaneous or planned, that causes your muscles to move and consume energy. Examples might include walking to class, carrying groceries, or dancing.

Physical Exercise
Physical exercise is a type of physical activity that is planned, structured, and done with the specific goal of improving or maintaining fitness. Examples might include running, lifting weights, or following a workout routine. All exercise is physical activity, but not all physical activity is exercise.

Physical Fitness
Physical fitness refers to your body’s ability to perform daily tasks or exercise with strength, endurance, and flexibility, while minimizing the risk of injury or disease. People with high fitness are often described as having a high capacity for functional movement and recovery.
