Fitness and health are frequently equated. They are diverse states of existence on a physical level. There is a distinction between being healthy and not being in shape. We can gain most from striking a balance between fitness and health. Here is a definition of the difference. The World Health Organization defines health as a condition of physical, mental, and social well-being in addition to the absence of sickness. Longevity and good aging are included. Contrarily, fitness is described as the capacity to engage in physical activity in relation to a certain set of traits one possesses or develops.
