GTG never worked for me for a longer time, same with Intensivstretching (same principle only for stretching) at some point I skipped sessions and then not to much later the whole thing collapsed.
Fair enough with that Kid but harsh.
I remember that Dan John in one of the Get Up! volumes stated, that he worked up to 20 pullups (or was it chinups?) but maybe I got that wrong. Perhaps he could state how he did it, please Dan?
BTW simply change chin-up to pullup in my posts above, I am too lazy to edit the posts. I throw these terms together often probably because my numbers are not that far apart...
