@Marjerda
If we need to go and get that important details from the other source (and from comments of random guys on internet at that), that means this manga did very poorly in the story telling department. Seriously, if I didn't see your comment I wouldn't understand this as well; just like hundred others here.
@Belrog yup, I said the same thing some chapters ago. This author doesn't know how martial arts or sport science work and just randomly writing whatever nonsense it came to his mind. It like a story written by a shut-in who never going out, let alone exercises, but assumes how thing work I'm the real world.
BTW, why 我流 (Garyuu) is transliterated and not translated as Self Taught here? I remember it was translated like this in the previous chapters.
