Fitness is a kind of exercise, such as all kinds of unarmed aerobics, rhythmic gymnastics, rhythmic gymnastics, and all kinds of self-resistance movements. Gymnastics and yoga can enhance strength and flexibility, increase endurance, and improve the ability to coordinate and control all parts of the body, thus making the body strong. If you want to relieve stress, exercise at least three times a week.

Swimming, brisk walking, jogging, cycling and all aerobic exercises can exercise the heart. Aerobic exercise has many benefits: it can exercise the heart and lungs, enhance the function of the circulatory system, burn fat, increase vital capacity, lower blood pressure, and even prevent diabetes and reduce the occurrence of heart disease. The American College of Sports Medicine suggests that if you want to know whether the intensity of aerobic exercise is appropriate, you can test your heart rate after exercise.

It is advisable to reach 60% ~ 90% of the highest heart rate. If you want to lose weight through aerobic exercise, you can choose low to moderate exercise intensity and extend exercise time. This method consumes more calories.

Exercise frequency is 3 ~ 5 times a week, 20 ~ 60 minutes each time. If you want to exercise your muscles, you can do weight lifting, gymnastics and other exercises that repeatedly stretch and flex your muscles. Muscle exercise can burn calories, enhance bone density, reduce the chance of injury, especially joint injury, and prevent osteoporosis.
