It's not anyone else who helps Du Xixi exercise, but the one closest to her, Ke Lian.
Logically speaking, Ke Lian, as the head of the Alliance Military Competition, shouldn't leave the Military Department for too long. Going home to rest daily is already a humane practice by the Military Department; previously, most heads stayed at the Military Department until the competition was over.
But the Military Department sympathizes that Du Xixi's situation was an unforeseen disaster, and they also hope that her physical abilities can improve with Ke Lian's help, at least to perform better during the Alliance Military Competition.
Therefore, Ke Lian, as Du Xixi's husband, was given leave by his superiors, and only needs to return if there are extremely important matters that require his involvement during the competition.
