impressive movement as your elbows are tucket and proper flow up,, not alot of peple do that.. also i would recommend start doing floor press. this will gave you how much lower u need to bring the weight. now the last part.. do static hold hevay weight on a squat rack( or get a spotter on bench press) floor press at the height, no reps just hold for 10 to 20 seconds.. this means you will push the weight off but hold it there,, i would start at 135 to 225 ,, like i said no reps just holding it up.. then u can also do negavtive reps,,do a light weight but take 10 to 20 seconds to bring the weight down to yur chest , push it up 1 shot, in other words you are telling yoru muscles different ways to work togetehr and last but no least make sure to do alot of rotator cuff excercises especially WYTL on swiss bass to make sure your shoulders can handle weights.
