17. Elements of Fitness To be physically fit, you must work on all five of the health-related components of physical fitness. What are these five components?

18. Elements of Fitness 1) Cardiovascular endurance: Cardiovascular endurance is the ability of the cardiovascular system to utilize and send fuel and oxygen to the body during long periods of activity.

19. Elements of Fitness Cardiovascular disease is the leading cause of death in the United States. Keeping your cardiovascular system healthy is the most effective way of reducing your risk of developing the disease.

20. Elements of Fitness 2) Muscular Strength: Muscular strength is the amount of force a muscle can exert.

21. Elements of Fitness You need muscular strength for activities that involve lifting, pushing, or jumping. This is necessary to carry out many daily tasks.

22. Elements of Fitness 3) Muscular Endurance: Muscular endurance is the ability of the muscles to perform physical tasks over a period of time without becoming fatigued.

23. Elements of Fitness Similar to muscular strength, muscular endurance is needed for activities that involve lifting, pushing, or pulling repeatedly. This gives you the necessary endurance to carry out daily tasks without becoming fatigued.

24. Elements of Fitness 4) Flexibility: Flexibility is the ability to move a body part through a full range of motion.

25. Elements of Fitness Being flexible can increase your physical performance, help you feel more comfortable, and reduce the risk of muscle strains and other injuries.

26. Elements of Fitness 5) Body Composition: Body composition is the ratio of body fat to lean body tissue (muscle, bone, water, connective tissue).

27. Elements of Fitness To look and feel your best, it is helpful to have some idea of your body composition (how much of your body is composed of fat and how much is composed of everything else). In general, males with 25% or more body fat and females with 30% or more body fat are at risk of developing cardiovascular disease. Carrying too much weight also places added stress on the skeletal system.
