Does weightlifting have a great effect on dimensional growth?

I think lifting weights greatly increases the latitude of muscles. First of all, I don't practice weightlifting, but all my muscle friends around me have come to the conclusion that it is true. I know three weightlifters. Although all three are students, the oldest is only 25, but they are all muscle tyrants. Let's start with the first one. The first muscle bully, a southerner, has been practicing weightlifting for nearly six years. According to him, the person who took him to practice at the beginning should be the apprentice of the deer god or the apprentice of the deer god (I can't remember), so I took him into the door. There should be no one who doesn't know the deer god. After some time, he chose to take the road of weightlifting. He is very talented in sports, extremely explosive and proficient in ball games. It's really awesome. The three items add up to more than 500 kilograms. (bench press 140 or squat 150 are all 220) He is not tall, but he is really big. What's more, among the students, he is bigger than the average person who has been practicing bodybuilding for 5.6 years, but his body fat is also high and his muscle separation is very average. When practicing together, a friend asked him how to practice, because the latitude is so big. He said that he practiced weightlifting, and the weight was big. His predecessors told him that if he played college students' bodybuilding or fitness competitions, he should not get any good rankings because his body fat was high and his separation degree was not obvious. But if he goes to the university weightlifting competition, he will definitely get a good ranking. The remaining two muscle strength weightlifters are also very big, and their muscle latitudes are indeed much larger than those who practice for the same time. The three events are equally amazing, but they are still worse than the first one. . . So these examples of gay friends around me make me believe that strength weightlifting is really helpful for latitude growth.
