Forearms are very big. One training is to hang two elastic balls the size of tennis balls from the roof, hold them with both hands and do pull-ups. You can't make one at first, but later you can make the same number as the monkey bar, and one group 19-22 can make four groups. In strength data, forearm flexion and biceps flexion are almost the same. There are not many squats. Basically, it is more complicated training, such as snatch and clean and jerk, including some functional strength movements to enhance strength. I think a seemingly simple and practical thing is to climb a heavy rope.
In fact, boxing, a training method, exercises muscles slowly and is more explosive. It may not be big to put Tai Sen in any gym in North America, but if he is allowed to do various compound sports, including strength weightlifting, his figure will not be bad. I trained an Indian about my height. I weigh 6' 1, 189 kg, and he weighs 6'. 173 kg, but his bench press limit is 3 15, which I think is very amazing for his weight. OHP is easier 160 kg+. Squats and hard pulls are 400+ relaxation.
So I think the above are the most ways to judge whether a person has boxing training experience. My boxing belongs to poor training, poor genes, short arm span, general flexibility of lower limbs and poor flexibility.
