What type of physical activity is aimed at making your body strong and healthy?

The focus of the question is on physical activity specifically intended to strengthen the body and improve overall health. The term "exercise" is widely understood to refer to structured and planned physical activities that are performed to enhance and maintain physical fitness. This encompasses various forms of movement aimed at conditioning the body, such as strength training, cardio workouts, and flexibility exercises.

While "fitness" refers to the overall state of health achieved through regular activity, it is not a type of activity itself. "Recreation" typically involves leisurely activities and may not necessarily focus on health or fitness. Similarly, "sports" are organized physical competitions that can contribute to fitness but are typically goal-oriented and often involve competitive elements rather than a broad focus on making the body strong and healthy in the same way exercise does. Therefore, exercise is the correct answer as it directly relates to the intent of improving bodily strength and health.
