It doesn't matter if it's only her second workout. What matters is she is unfit, gained about 20 pounds of weight, and the World Championship is only a week away.
It seems to me, after she got her first olympic medal in Tokyo, she couldn't motivate herself for gritty trainings (She is satisfied. She is ok with her career, even if she doesn't win any more gold medals. Note: she only won gold medals at Doha and Tokyo)
