Precautions:

It is not advisable to do physical exercise on an empty stomach. Long-term fasting exercise in the morning consumes a lot of energy in the body, which is not good for the body. It is best to start light activities after eating in moderation, so that the muscles, joints and internal organs that have rested for a night and have been in a quiet state for a long time can be actively moved.

Don't engage in strenuous activities immediately after meals. After a meal, a lot of blood flows to the digestive system. At this time, if strenuous exercise is carried out, blood will flow to the motor organs to ensure the needs of muscle work, which will lead to insufficient blood supply to the digestive system, slow gastrointestinal peristalsis, affect the normal progress of digestion and absorption, and seriously lead to stomach pain, indigestion, ulcers and other diseases.
