It is normal for jumping to lose weight and rebound. Aerobic exercise can reduce fat, but it cannot improve basal metabolism. If you want to lose weight without rebounding, you must improve basal metabolism, and the improvement of basal metabolism depends on resistance training.

If you don't want to rebound, you should control your diet, reduce your calorie intake and not stop exercising. It is more appropriate to arrange training 3-4 times a week. Losing weight is a lifelong career, and maintaining a good figure requires establishing a reasonable lifestyle.
