thanks for the updates guys
victory meal plan for him called Operation Soup Dish (Shirumono Sankusen). Yuzu's weakness is he gets sick easily, which affects his performance. He doesn't have enough stamina to complete his FP. The dietitian was surprised to learn that Yuzu can't be bothered with food. So he focus on the activation of Yuzu's digestive system by feeding him something easy to eat such as soup and nabe. Even when in Sochi, the dietitian has been preparing the so-call victory nabe meal for him everyday. On top of that, Yuzu has been drinking the Amino acid from Ajimonoto. That helps to improve his diet as well.
He said that back when he was 15-16 y/o in the Miyatella (or something like that) Stadium program, can´t find the video in youtube but is the one where he does his split.Yes, I think he said he eat whatever he wants whenever he wants before.
Based on what I have read from other skater the choreographer will present the music an idea for programs and them they will choose. Then they go ahead designing the program. So is more the idea as the choreographer same as when you go to the balled.
I don´t think it will come from Yuzuru to pick a piano piece, specially when he doesn´t like piano.
