O and if you don't mind to explain what is "Active dynamic stretching with foam rolling "?
Good posts Tony. I used to always stretch inbetween every set. The reason why I dont anymore is that when exercises are done properly, every rep should incorporate a good stretch. Stretch and contract pretty much sums up resistance training. That elasticity that the muscles have will help to produce power in lifts and consequently hypertrophy.
Upper body ones are a little different, though. Wall sides, CKC's, dynamic blackburns, etc, are all examples for upper body dynamic warm ups. I'll try to explain those if anyone wants me to.
What have I got on the stretching topic? Nothing, sorry. :carduindisguise
Stretching has been shown to decrease power output. So any form of static stretching before the lift will not be very beneficial. Personally, doing particular stretches that mimic the oncoming movement really benefits me more than foam rolling, etc.
I don't believe stretching prevents injury. That said, I feel stretching in general before certain sporting events are used to bring the team together to focus. Same applies in the weight room.
Stretching at certain times can definitely be positive. But employing it in your routine I don't think is needed whether your goal is hypertrophy or strength improvement.
