You can't practice a certain part to lose weight, but practice the whole body. Running is an exercise that can be exercised in all parts of the body, but if you want to lose weight, you must persist and persevere, running for 3 to 4 days a week. It is best to run once every other day, and make sure that the running time exceeds 40 minutes. Only at this time can the body's fat and carbohydrates be combined to achieve the purpose of losing weight. Stick to it for a month and there will be surprises.
