Explain why improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for improving body composition.

Answer and explanation;

Exercise uses energy, and when energy expenditure exceeds energy intake, the difference is made up by burning fat. Thus, improving one's cardio respiratory fitness and muscular strength and endurance can help improve one's body composition by changing the ratio of body tissue to fat.

Muscular strength is a measure of how much force a muscle can exert in a single effort, while muscle endurance describes the ability of muscles to contract repeatedly over time. Muscle strength and endurance develop together: that is, building muscle strength also helps build endurance and vice versa.

Sustained physical activity allows the body to work its muscles while providing oxygen to the muscle groups. This activity develops the muscle groups in addition to the cardiovascular and respiratory systems that deliver oxygen to the muscles via blood circulation.
