1. It varies from person to person. People who lose weight must have a physical examination before exercise. If they suffer from severe coronary heart disease, hypertension, hepatitis and nephritis, they should not do a lot of physical activity. They should treat diseases first, and choose appropriate projects, such as walking and Tai Ji Chuan. Step by step. Obese people usually lack physical exercise, and their cardiopulmonary function and joint flexibility are relatively poor. Therefore, it is not appropriate to do a lot of exercise at first, and the amount of exercise should be gradually increased, which usually takes 2-4 weeks to adapt. 3. Be fully prepared. Before each exercise, you should do some preparatory activities, such as moving the upper and lower limbs and waist, so that the muscles and tendons of ankles and legs can be fully moved, increasing the gas exchange in the lungs, increasing the output of the heart, and avoiding muscle and ligament strain and palpitation and shortness of breath. 4. Appropriate activities. Too little exercise can't achieve the goal of losing weight, and too much exercise will have side effects, especially for obese people and the elderly with other serious chronic diseases, so we must pay special attention. Generally speaking, the amount of exercise should be moderate, and the pulse rate after exercise should not exceed 150 times per minute for young people and 1 10 times per minute for the elderly. There should be no dizziness, nausea, vomiting, pallor and other symptoms during exercise. Muscle aches after exercise, sleep and appetite are normal. If there are symptoms such as headache, loss of appetite and insomnia, it means excessive exercise. 5. Relax after practice. Relaxing activities are also called tidying activities. After each exercise or at intervals, do some slow-paced activities, such as walking, jogging, deep breathing, etc., so that the heart, breathing and blood pressure can return to normal as soon as possible. 6. stick to it. We must persist in physical exercise, we can't practice if we want to, and we can't practice if we don't want to. Stopping practicing is not good for losing weight and health. Parents should urge their children to exercise and set an example by themselves. 14, remember the 20-minute rule: it takes your brain about 20 minutes to confirm that you are full. The way to deal with it is to chew slowly and drag on for a long time. If you eat too fast, your appetite will definitely exceed the standard. You should try to drink some hot soup instead of wolfing it down. 15, go out for a walk with friends. Walking can consume the calories absorbed by the body, lower your blood pressure and heart rate, refresh you when you are tired, calm you down gradually when you are upset, and at the same time, let you have more contact with nature and friends. Wear high-quality sports shoes when walking, and maintain proper posture: look straight ahead, tuck in, lift your hips, straighten your back, and don't bend over to look at your feet. 16. Instead of taking the elevator, you should take the stairs, which can not only "burn" the body heat, but also enhance the heart function and prolong life. 17, you can go to the hill near your home for climbing exercise every morning or evening. While you enjoy the beautiful sunrise and sunset, the heat in your body has quietly disappeared. 18. Go to work by bike as much as possible. If the work unit is too far away from home, you can go to a place close to the unit by car first, and the rest depends on riding a bike or walking. 19, treat housework as an interesting aerobic exercise, and the calories consumed are enough to surprise you. Mopping the floor 1 hour can consume 250-400 calories; Ironing clothes, 205 calories; Make the bed, 2 10-240 calories; Washing clothes, 160 calories. 20. Proper dress can make you look thinner: you should wear clothes with long straight lines or diagonal stripes, and V-shaped neckline and narrow pointed collar can also visually produce some weight loss "effects". The clothes should be darker and cooler, the fabric should be smoother and the pattern should be smaller. 2 1, the clothes should look good. A glance envied by others can give you enough confidence and motivation to stay slim. 22, for the setbacks that may be encountered in the process of losing weight, we should have enough psychological preparation and find ways to overcome them. List common problems and obstacles, and write down your handling methods once they appear. Always keep a positive self-dialogue. When you encounter setbacks beyond your control, you should tell yourself that you have done your best and should continue. No matter how hard you try, you can't control everything in your life, so you shouldn't criticize yourself when you are temporarily frustrated. 23. Tell others the results of your weight loss, so that you will immediately win the respect of others and get wide support. In addition, constantly telling others about your achievements can make your dreams come true every day. 24. Don't weigh yourself repeatedly for three days. Because the amount of water trapped in the body varies from 1-4 kg every day, and the weight of muscle is greater than fat, weighing yourself every day will make you lose confidence. On the other hand, we should always pay attention to whether the clothes we wear still fit, so that we can constantly see our progress and keep enough motivation at all times. Don't think that you can consume all the calories you eat into your body through physical exercise. You can't and shouldn't do this. In order to find out how much food you can eat every day without gaining weight, you should record the calories you consume in your body and the calories you consume through exercise every day. It is important to remember that under no circumstances should your daily calorie intake be less than 1200 calories.
