Scap Movement During Bench Press?
I didn't know where else to put this, so forgive me if it's the wrong place. I recently came upon a video of a guy who (as I understand it) coaches powerlifters. He explained that people are setting up for the bench press wrong and then suggests the "correct" way to do it. This was advise for everyone, not just powerlifters.
He says we should be in scapular retraction at the bottom, but not at the top. When setting up for the bench press we're supposed to be arching the back 1st and then focusing on keeping our shoulders down, not together (to put it very simply). When the bar comes down, is when the scaps are supposed to pinch together. When the bar goes back up, the scaps go apart again. He says doing this allows you to get more out of the natural pec movement and thus a lot more benefit from the bench press. It also takes stress off the shoulders and biceps, according to him.
When he gets the model to do it (who does look pretty darn strong), it SEEMS as though all the weight is on the tops of his shoulders and his scaps are floating free to move. But I tried this myself and they still don't move with max weights. Focusing on scap movement is REALLY awkward as well. My shoulders don't feel as stable for one thing, and my scaps either need to be together or apart during set up and I suspect the correct way is pinch together like everyone else does and then don't worry about it.
Am I missing something about this whole thing? The reason I was even listening to someone about technique is because I'm an intermediate who had taken on the close grip bench press into my programming. I found I get really bad shoulder pain even with (according to coaches here and elsewhere) perfect technique. Now having experimented with it for a very short time and dropped it, I've got nagging pain that comes and goes randomly during my regular bench press.
I know it could be just soreness that is taking a really long time to go away because I'm still hammering it with presses, but I want to make sure I'm not missing anything after this guy got me scratching my head.
