A lot of guys are guilty of being front delt pressers (basically using your delts to get the weight up) when they bench. Learning how to bench the right way takes some effort, watching videos of people with good form helps a lot but still doesn't show you how your supposed to feel when your benching the right way. With that said, i encourage all you guys to read this short quote by DC then start every chest day out with what he says in this quote until your at the point where you no longer have to think about it. Doggcrapp "Go get some 20-40lb(something light for you) dumbells and lay down on a flat bench but i only want you laying down with the top half of your back on the bench--your ass and your lower back will be off (the edge) of it, now lower the dumbells as deep as they can go and at the bottom drop your trunk (ass) as low as you can and raise your ribcage high (like you would do if you were doing a cross bench pullover)-----now hold that position throughout the whole movement--and press the dumbells 10 times (and keep that ass down and sternum up-in that same position I told you to hold ...on every rep down at the bottom sink the dumbells as low as you can go for a deep 1 second pause before pressing....do not let your delts roll forward like every newbie does. A newbie presses and then flattens his chest and rolls his delts forward at the end of a press See how that feels? Thats how you should be doing every single chest exercise--with that same exact feel. (im not suggesting lifting like that on everything--im trying to get you to know the difference between a chest presser and a front delt presser) so you personally adjust yourself (shoulders back and down, pinched shoulder blades, chest high, sternum high) on every chest exercise you do"
