Some common mistakes in fitness

　　Mistake one: I think morning exercise is best. Many people like morning exercise , thinking that the air is fresh in the morning, but it is not. Air pollution is worst in the morning. Moreover, people's blood has high viscosity in the morning and is prone to thrombus formation. In fact, the heartbeat and blood pressure are the most stable at dusk, which is more suitable for fitness.

　　Mistake 2: Ignore the warm-up. Preparing for activity is an essential step in fitness. Warming up before activities can increase body excitement, reduce muscle viscosity, increase joint flexibility, and avoid sports injuries.

　　Mistake three: Keep exercising even when you are sick. This is the most dangerous. If you feel unwell, you should suspend or reduce exercise, otherwise it will aggravate the condition and cause irreparable consequences. Especially the elderly, whose own immunity is weak, must stop fitness activities when their bodies are in an abnormal state.

　　Mistake four: Activities on an empty stomach. Many people (especially in the morning) like to exercise on an empty stomach, which is very wrong. Exercise requires energy. Lack of energy can cause dizziness, rapid heartbeat, cold sweats, and other problems. In severe cases, sudden death may occur.

　　Mistake five: The more exercise, the better. Overloading exercise can lead to discomfort such as excessive fatigue, body aches, and even tendon and muscle strains. The correct exercise method is: start with a small amount of exercise and gradually increase the amount of exercise.
