Trainers are usually underestimated by their trainees, especially boxing trainers. Trainees seem to forget that the trainers have 2 times more experience than they have. We have found a video that puts a picture what trainers can do.
Apparently, a 60-year-old veteran takes on a young boxer in a sparring session. As usual, the boxer takes things lightly and laughs at his opponent. However, the boxer’s opinion will change quickly.
The veteran and the boxer starts the fight in a friendly. The boxer is laughing and the veteran is warming up. The boxer throws the first punch which does no damage to the old man. After the first punch, they both dance for a little while.
