Speaking of weightlifting, what do you think? Is it the scene of strong women and men gritting their teeth and grabbing the barbell, or is it the scene of stout players squatting in front of the barbell and moving their fingers to prepare? These are all the inherent impressions we have seen from TV broadcasts. What are real weightlifters, especially women weightlifters, like? On the afternoon of November 8, the reporter walked into the weightlifting training hall of Qingdao Sports School to find out. This team, which has just won both the gold medal and the total number of medals in the Provincial Games, includes not only women and men, but also young women with great figure.

Of course, the pullback, I emphasize very much.
