Make a feasible long-term exercise plan. Exercise is not enough. The best exercise to lose weight is skipping, jogging, walking and other aerobic exercises. These exercises must last for more than 40 minutes at a time, otherwise you can't lose fat. Losing weight means reducing fat, not water. Therefore, you should replenish water before and after exercise. It is recommended to exercise with many people and participate in aerobics classes. It's easier to lose weight by joining group exercise.
