Some background information
Regular physical activity helps improve your overall health and fitness, and reduces your risk for many chronic diseases.
Being “fit” essentially means being able to perform well in a wide variety of physical exerting circumstances. For some people, it also means being able to "fit" into their favorite clothes. Either way, if you find yourself running out of breath when doing simple things like walking up a few stairs or playing catch, it's time to improve your physical condition.

Some background information
Regular exercise is a critical part of staying healthy. People who are active live longer and feel better. Exercise can help you maintain a healthy weight. It can delay or prevent diabetes, some cancers and heart problems.

Some background information
Most adults need at least 30 minutes of moderate physical activity at least five days per week. Examples include walking briskly, mowing the lawn, dancing, swimming for recreation or bicycling. Stretching and weight training can also strengthen your body and improve your fitness level.

Some background information
The key is to find the right exercise for you. If it is fun, you are more likely to stay motivated. You may want to walk with a friend, join a class or plan a group bike ride. If you've been inactive for awhile, use a sensible approach and start out slowly.

Physical exercises
Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health.
It is performed for many different reasons. These include: strengthening muscles and the cardiovascular system, honing athletic skills, and weight loss or maintenance. Frequent and regular physical exercise boosts the immune system , and helps prevent diseases of affluence such as heart disease, cardiovascular disease, diabetes
(糖尿病）
and obesity. It also improves mental health and helps prevent depression.

Types of exercise
Exercises are generally grouped into three types depending on the overall effect they have on the human body:
Flexibility exercises such as stretching improve the range of motion of muscles and joints Aerobic exercises such as cycling, swimming, walking, rowing, running, hiking or playing tennis focus on increasing cardiovascular endurance.
(Aerobic exercise refers to exercise that involves or improves oxygen consumption by the body. Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic or energy-generating process.) Anaerobic exercises such as weight training, functional training or sprinting (a short, fast running race) increase short-term muscle strength.

Exercise benefits
Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a healthy weight, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system .
Frequent and regular aerobic exercise has been shown to help prevent or treat serious and life-threatening chronic conditions such as high blood pressure, obesity, heart disease, Type 2 diabetes, insomnia, and depression.

Exercise benefits
Physical activity is thought to have other beneficial effects related to cognition as it increases levels of nerve growth factors, which support the survival and growth of a number of neuronal cells.
Both aerobic and anaerobic exercise also work to increase the mechanical efficiency of the heart by aerobic exercise, or strength training. Such changes are generally beneficial and healthy if they occur in response to exercise.
2020/5/1 School of Foreign Studies 10
Exercise benefits
Not everyone benefits equally from exercise. There is tremendous variation in individual response to training: where most people will see a moderate increase in endurance from aerobic exercise, some individuals will as much as double their oxygen uptake, while others will never get any benefit at all from the exercise Similarly, only a minority of people will show significant muscle growth after prolonged weight training, while a larger fraction experience improvements in strength. This genetic variation in improvement from training is one of the key physiological differences between elite athletes and the larger population. Studies have shown that exercising in middle age leads to better physical ability later in life.

How to Become Fit
Do you know that it is possible to lose weight with help of your thoughts only! Yes this is indeed true. You need to do certain things if you desire to be successful.
The first and foremost thing is to get rid of the negative thoughts related to weight. You are always lectured that eating a particular dish will make you fat. Or some attribute the excess weight as hereditary. Your family members say that losing weight is much more hard once you cross 40 – all such thoughts gradually become the truth for us since we start believing in them over a period of time. Even if you try hard to lose weight, your beliefs and thoughts have made it an impossible task. What you believe has a lot of bearing if your efforts will bear you results or not.
2020/5/1 School of Foreign Studies 12
The next step you have to do is look at the thoughts and beliefs you carry regarding exercise, fitness and diet. Remember what you believe in is the truth for you – so if you think sitting at the desk with not much of physical activity will get you fat, you will for sure gain weight. The results we expect also decide what really occurs. So in order to have the right results you will have to change your thoughts. Change your thoughts and see the difference you experience in the results too. You can be entirely in control and can work towards achieving the results you desire.
2020/5/1 School of Foreign Studies 13
We relate our bodies to our self image. But you are wrong in believing so. It is your skills, your attitude, your abilities and your heart that defines you. it is not your body that is the real you. But how you think about your body will affect a lot of things. So change the way you think. On looking into the mirror do you feel sad and depressed? It is this negative energy that is responsible for your weight gain. Whenever you are thinking negative, you attract thinks alike.
2020/5/1 School of Foreign Studies 14
Hence if you want to do good to yourself and want to get fit, you have to be open and not be prejudiced. You should care for your body so that you lead a healthy and happy life. So the first step is to start loving yourself. Look into the mirror and feel good about yourself. Try this for some days and you will definitely be better. You will soon be inspired to change your thoughts into positives so that you also attract good things that will make your body fit and healthy.
