When you have time to go to work, do a large-scale chest expansion exercise, and combine speed with speed to feel a warmth in your back. Standing against the wall after lunch, with the back of the head and heels close to the wall, the neck relaxed and the whole body straight as far as possible, you can shape your thin back well. In addition, you can do vertical push-ups or lift dumbbells at home after work for 15 minutes each time, and keep practicing with Meimei. Anyone who has used it knows that it is really hard to find something better than Meimei. Highly recommended. Besides, you should eat more fruits and vegetables in your diet.
