I actually don't think yuzuru's health is a big issue. All athletes have injuries and health problems. Compared to other Olympic champs last season, yuzuru's health problems were not as bad. Doctors only asked him to rest for a few weeks and he could resue training after a few weeks. The other Olympic champs also got injured but was told by the doctors to rest for a few months and they had to take the whole season off. The main issue yuzuru faced last season was the loss of training time due to multiple injuries and health problems. But the health issues themselves are not as severe as the health problems the other Olympic champs experienced. I don't think he is physically weaker or less healthy than most athletes. Maybe I'm just optimistic.
I don't think he has any health problems right now. In those practices he looked suuuper fit. I have never seen him more fit to be honest. He nailed clean LP with 3 quads yesterday and he didn't looked even too tired
