The state of being healthy and strong, often achieved through exercise and good nutrition.
Regular exercise is important for maintaining good fitness levels.
Fitness is derived from "fit" (from Old English "fitt", meaning suitable or proper) and the suffix "-ness" (meaning the state or quality of). The word "fitness" refers to the state of being suitable or in good condition.
Think of being 'suitable' or 'proper' ('fit') and the '-ness' indicating a state. This helps you remember that 'fitness' means the state of being in good condition.
