stretching is a grey area IMO. Someone who is very unflexible is obviously going to benefit from a bit more and someone who is very flexible should be working more on stability. In practice, it seems that people like to do what they are good at, so we see desk jockeys who can't touch their toes doing SFA stretching and crazy flexible (most of the time) ladies doing a heap of stretching.
Weird.
Me personally, I do hip flexor, hamtstring, groin, thoracic spin mobility (which also does pecs) and then the lat stretch. I'm super tight and if I don't do that I cannot squat to depth.
