'How Bodybuilders Should Eat' Article Questions

I love the article right here

But I have a few questions.

  1. Can the approach for this cycling method always work for cutting and bulking and tweak it until it suits the calories needed in a cut or bulk ?

  2. Another thing, it seems like you need to have high days for legs. I understand the low days, when you don’t work out you don’t need as much. But when do you know when to use the medium days? Like when you have chest workout days?
