history: Hey do you go to the gym? I do not, did you know that "fitness" meant being able to do the day's stuff without being excessively tired? This was before the Industrial Revolution. That's interesting! What does it mean nowadays? Not sure about if being now but the definition is the state or quality of being fit. Oh okay, I heard there was a more modern definition, that one just seems a bit general. Yes, the modern definition talks of a machine or person's ability to do a specific thing, it can also be a holistic definition about a person's adaptability with varying situations. You know so much about physical fitness, I am trying to get my body more in shape after having 7 children.
knowledge: Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
