Girls usually go to the gym to do aerobic exercise, do some jogging or running on the treadmill at a speed of about 6 kilometers per hour, or do aerobic exercise such as spinning or yoga. 45 minutes a day, losing about 5 pounds a month should be no problem. In addition, for local dissatisfaction, you can do some small equipment and small weight anaerobic exercise. For example, you can practice some dumbbells with thick arms. Girls don't have to worry about long muscles, because women don't secrete testosterone, so being a woman doesn't have to worry.
