- In modern society, many people find that they do not get very much exercise.
- They travel by bus, train, or car, and they can move up or down in elevators.
- They have machines that do most of the heavy work that was once done by people.
- However, exercise is important for staying healthy.
- A person who exercises frequently will be physically fit.
- There are different aspects of physical fitness.
- One important element of being physically fit is called cardio-vascular fitness.
- The word cardio-vascular refers to the heart and lungs.
- If one's heart and lungs are in good condition,
- then one can exercise at a steady pace without soon getting tired.
- To develop cardio-vascular fitness,
- it is important to perform some exercise that makes one's heart beat quickly.
- For example, a person can improve cardio-vascular fitness by riding a bicycle,
- by running, by swimming, by rowing, or even by walking quickly.
- Some people go to special places, called health clubs or gyms
- where they can use different exercise machines to develop their cardio-vascular fitness.
- But many people improve their cardio-vascular fitness by playing recreational sports,
- such as tennis or soccer, or by dancing vigorously.
- By having good cardio-vascular fitness, one is less likely to suffer from heart disease.
- Of course, there is one way to improve cardio-vascular fitness that does not involve exercise-stop smoking!
- Another important aspect of physical fitness is called flexibility.
- Flexibility refers to one's ability to stretch comfortably.
- For example, a healthy person should be able to touch his or her toes without bending the legs.
- People can perform various stretching exercises to improve flexibility.
- By being flexible, a person can avoid injuries that might otherwise affect their body.
- Yet another important aspect of physical fitness is the strength and endurance of one's muscles.
- Many people suffer from injuries that result, in part, from weakness of the muscles.
- Muscular strength and endurance can be improved by a variety of exercises.
- Some of these exercises involve lifting a weight,
- but other exercises simply involve pushing or pulling against the weight of one's own body.
- One example is an exercise called the push-up.
- In this exercise, a person lies on the floor, with the face pointing down.
- The person bends his or her arms,
- so that the palms of the hands are on the floor, next to the shoulders.
- The person then pushes with his or her arms,
- lifting the upper part of the body above the ground until the arms are straight.
- Before starting to do any exercises, it is a good idea to have a medical check-up.
- Some people do not want to exercise because they think it will be too much work.
- However, many people find that they feel very good when they exercise.
- Exercising can be an enjoyable and fun way to maintain health and fitness.
