First, if fitness is anaerobic training, swimming is best aerobic, so exercise first and then swim. First swim and do aerobic exercise to warm up, at the same time burn excess fat, and then exercise, get twice the result with half the effort. Aerobic exercise (running, swimming, skipping rope, etc. ), the intensity of these exercises will not be too great, but it must exceed 30 minutes.

Second, if fitness is aerobic training, swimming is better without oxygen, or fitness first and then swimming. Fitness can only carve the muscle lines of the abdomen. If there is fat, you must start with aerobic exercise and burn the fat before you can start carving. Many people think that fitness can eliminate abdominal fat and other fats, which is a wrong concept. Without burning fat, no amount of training is in vain.

Third, in short, put the anaerobic ones in the back, and put the strenuous exercise in the back. If you want to exercise to make your body more fit, you must persevere and last for more than half an hour. Because at the beginning of exercise, the body consumes muscle instead of fat.

What is fitness?

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 can enhance the strength, flexibility, endurance, coordination and control of 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 to reach 60%-90% of the highest heart rate after exercise.

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. ?

Before you lift weights, measure them. If you can lift eight times in a row, practice from this weight. When you can lift this weight 12 times in a row, try to increase the weight by 5%. Pay attention to lifting 8- 12 times in a row every exercise, so as to reach 70%-80% of the maximum endurance of muscles, and the exercise effect is good. 2-3 times a week, but avoid exercising the same group of muscles for two consecutive days to give the muscles sufficient recovery time.
