When a girl comes to the gym for the first time, can you give me some guidance on how to lose weight, how to allocate aerobic and anaerobic exercise, how to exercise several parts every day and how to walk several times a week? When you come to the gym for the first time, you can practice your chest, shoulders, back and legs in turn. Of course, you can combine the abdomen every time. You can practice the four major muscle groups once a week for one hour at a time. After exercise, you can do aerobic exercise for 30 minutes. This is a pure body fat brush. Aerobic exercise can choose elliptical machine or bicycle treadmill. You can choose your own speed and resistance. You can drink water every time you finish an action, as long as you don't drink water.
