This is the fat man himself. Because of obesity, he became more and more insecure. Even at work, he seems very cautious. It is precisely because he doesn't want to go on like this, he has no self, let alone the problem of finding a girlfriend. So, he began a period of self-slimming. At this stage, he must insist on skipping rope for at least 50 minutes every day.
Of course, it's nothing. I have been jumping fast for 50 minutes, but I rhythmically adjust the speed to a fast and slow way, so that my breath floats with the jump. I remember he told me that when he jumped for 50 minutes for the first time, he had an illusion that he was going to faint, but he still gritted his teeth and spent that long 50 minutes.
