I was hoping I could get you to say a little more about their “extreme stretching” and what you think of the science behind it — I’ve heard it said (e.g., by John Paul Catanzaro http://www.tmuscle.com/readArticle.do?id=459380) that stretches longer than 15 seconds or so can actually be counterproductive (Catanzaro cites muscle hypoxia and even scar tissue growth after 60 sec. or so). At minimum, it doesn’t seem like there’s much supporting evidence for the idea of long (60-90 sec.) loaded passive stretches doing much good if one’s primary goal is muscle gain. What do you think?

this is a big difference for the biceps tendon (being stressed on 3 non-consecutive days vs 4 times per week)
