In his video at about 7:56 Tate states the problem that your average gym goer does with the bench press is they really lower the elbows in relation to the bench -- I couldn't tell if it was because they are lacking the arch or is it where they bring the bar down to on their chest?
He also states that how you move the bar, obviously, affects what muscles you're targeting. I notice when I bench sometimes my anterior delts begin to burn a lot... proper movement of the bar is from about nipple line and then you drive it above to eye level? I think I've been just trying to bench as vertical as possible... boy I have a lot to learn. Thanks!
