1. Only do aerobic exercise and ignore strength training. Many people only do aerobic exercises such as running and cycling, but ignore strength training. In fact, strength training not only helps to strengthen muscles, but also improves basal metabolic rate and helps to reduce fat and shape.

2. Long-term low-intensity aerobic exercise can burn fat. Although low-intensity aerobic exercise can indeed burn fat, it takes a long time to see the obvious effect. High-intensity aerobic exercise can quickly improve cardiopulmonary function, and the effect is better.

3. Improper use of fitness equipment. Many people do not master the correct methods and postures when using fitness equipment, which is easy to cause injuries.

4. Do not rest before and after fitness. Failure to rest before and after fitness can lead to physical fatigue and injury.
