In order to lose weight, we need to consider both diet and exercise. In terms of diet, choosing foods rich in minerals and cellulose is the key. These foods include seaweed, soybeans, celery and kelp, which help to provide nutrition and help control weight. Cellulose can increase satiety and reduce the possibility of overeating. Secondly, in the aspect of arm exercise, some special movements can be carried out to exercise arm muscles in a targeted manner. For example, cross your hands over your head, then hit your arms down, or use a small dumbbell to make a straight move. These actions can effectively stimulate arm muscles, promote fat burning and muscle shaping. In addition, aerobic exercise is also an effective way to reduce body fat, such as running and swimming. These exercises can improve the metabolic rate of the whole body, help burn more fat, and thus achieve the effect of slimming arms and big arms. To sum up, through diet control and special arm exercise, combined with aerobic exercise, you can effectively reduce the fat of your arms and arms.
