Just a note to all that a mate of mine tested out the keep in the pit bull bible and came out tops in 34mins. The feed keep was adjusted a bit as some things we get here and some not, but overall his dog was in great shape for a guy who has only ever conditioned once before and saw his ass in under 20 mins. I told him I believe he could still go a little lighter on the weight side but I was surprised to see his hound look so good from the first to this one.
