When doing chest should the elbows be flared out parallel to shoulders or sort of inwards...I was watching a video where the person said if u flare your elbows out to much you'll be hitting more delts?
SOOOO TRUE!i think that is a question of personal biomechanics, i think each and everyone of use is unique and you should find your own groove in pressing movements. allow your body to find its natural way of moving thru the range of motion, dont force it one way or the other, find the middle ground.
i started doing this about a year ago, i will flare the elbows out so the are in line with one another... i will bring the bar down to 2 inches of my neck and press up in a simular fashion...i cant go nearly as heavy (70% of what i used to do) but my chest has grown leaps and bounds from it.... i am able to feel the chest working much more effective this way, as opposed to the shoulder and tri....
i dont know about the tendon being stressed or what that is supposed to mean?
A muscle Stretched with resistance receives maximum overload. Flaring the elbows and bringing the bar more toward the neck targets chest must better.
if it hurts or you get injured. You were using too much weight.
