Describe the components of health-related fitness.

Answer:

The components of health-related fitness are cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition. Cardiorespiratory endurance is the ability of the heart and lungs to supply oxygen during sustained activity. Muscular strength is the greatest force a muscle can produce, while muscular endurance is its ability to keep working over time. Flexibility is the range of motion around a joint. Body composition is the proportion of fat, muscle, bone, and other tissues in the body.
