Some people advocate exclusively one range or another for a particular body part or region. A friend is fond of saying, "backs love volume", but but I answer, "don't they love intensity, too?" People often train DL low-rep only, but doesn't your PC benefit from volume? Is there any muscle or body part that benefits from one volume-intensity range and not another? I'm not saying that you have to train all ranges all the time, but that there are times that any given body part can benefit from one or the other. For a priority lift, I'm usually doing both, but for other lifts, one or the other.
