What type of physical activity is planned and structured for improving fitness?

Exercise refers specifically to planned, structured, and repetitive physical activity aimed at improving or maintaining physical fitness. This definition distinguishes exercise from casual or spontaneous activities, such as recreational play, which may not be organized or intended specifically for fitness purposes.

For example, while a session of dancing with friends may improve fitness, it is not typically planned with the goal of meeting specific fitness objectives. In contrast, a scheduled workout routine that includes strength training or cardio exercises directly targets physical health improvements.

Other options, such as recreation, may involve physical activity but do not necessarily have a structured approach aimed specifically at fitness enhancement. Aerobic activity is a subtype of exercise focusing on improving cardiovascular endurance but does not encapsulate the broader concept of exercise. Lastly, physical wellness encompasses overall lifestyle choices that contribute to health, which may include exercise but is not limited to it.
