Spring is a lazy season, and the phenomenon of spring sleepiness seems to exist in everyone. Therefore, people don't want to exercise on rainy days, but if you know how to keep fit, you should exercise more, regardless of spring, summer, autumn and winter. 1. Go quickly: Walking is the easiest aerobic exercise, and it has the best effect on improving cardiopulmonary function and oxygen uptake. It can also improve coronary atherosclerosis, lower blood pressure, regulate blood lipid and regulate blood sugar. Recommended exercise frequency: walk about 4.5 kilometers a day for more than 30 minutes each time, about 5 times a week. If you are busy at work and can't spare the whole time, you can spend 10 minutes in the morning, afternoon and evening. Walk quickly or use crutches with both hands to make the movements more coordinated and stable.

2. Swimming: Swimming has a magical exercise effect on the nerves, breathing, digestion, muscles and blood circulation of the human body, and it is a relaxed and pleasant whole-body exercise method. Dr Carl Denison, a 67-year-old American family doctor, swims five times a week. He said: "When you enter the water, all the pressure disappears. Swimming makes my body more flexible, the pain disappears and my heart is younger. "

3. Dancing: Dancing is a kind of whole-body exercise, which can relax the body and mind, make people feel happy, relieve stress, promote blood circulation, increase oxygen intake and be beneficial to heart health. Experts suggest that you can find a partner to participate in the dance class with corresponding intensity according to your physical condition. If there is no dance class nearby, you can dance to your favorite music for 30-45 minutes at home.

4. Cycling: Studies have found that the habit of cycling can enhance cardiovascular function by 3%-7%. The change of heart rate also varies according to the speed of pedaling and the ups and downs of terrain.
