1, a balanced diet.

You must have a good posture before exercise, and a balanced diet is very important. Keep junk food in moderation, insist on drinking skim or 2% milk, drink more water and eat more fruits and vegetables.

Step by step.

Step by step will make your exercise safer. If you don't have much activity at ordinary times, you must pay attention to the right amount at the beginning of exercise, and don't overestimate your own exercise. You should increase your exercise step by step. It is very important to do warm-up exercises before exercise to avoid cramps caused by exercise.

3. Breathe correctly.

Pay attention to breathing during exercise. Especially when running, breathing should have a certain rhythm. When breathing through the nose and mouth at the same time, the mouth does not need to be too wide, and the tongue can be rolled up to prolong the time of air in the mouth and reduce the stimulation of cold air to the respiratory tract. Pay attention to exhaling gas from the lungs as much as possible every breath to increase the effective ventilation.

4. Replenish water. It is necessary to replenish water reasonably according to your own amount of exercise, and be careful not to binge drink when drinking water, which is not good for your stomach.
