I wouldn't recommend that you watch this video - I still haven't watched it with the volume on. It pains me to think about this one:
I've seen it already, that guy is on steroids. Guys on steroids should never max out or go below 10 reps, only natties can go down to maybe 5 reps, but anything below 5 reps is too dangerous even for natties, unless you are a powerlifter, in that case is different since the body gets used to extreme heavy weights, but enhanced bodybuilder should stick to high rep work
