Best chest movements in my eyes are high cable flyes,dips and low incline db press. Best pump is from the first two as I don’t get much of a pump from incline dbs as my shoulders seem to take over but I do notice thicker upper pecs when doing them as opposed to not doing them.
With all that said I have done dips extremely heavy and high volume for 30 years and it has made my pecs very large but also gravity takes over at some point and you get the saggy pec look so best not to get pecs to big anyways.
