Hello I am new here, but I would like to comment. I agree with the guy that said you need a strong back. Without it you are just wasting your time. My chest does not grow like I would like it to, but it is very strong. I weigh a meager 175 at 5'8" and can press about 385, I have done 415 a few months ago. But I took a long break from the gym due to work. Keep in mind this weight is on a regular old fashioned free weight
bench press, not any of these new fancy strength machines. But this brings me to my point, you should never be able to row as much as you are benching, seated or bent over, your lower back just is not designed for that. You want a wider chest do wide grip, or lighter full flys. You want thicker do concentrated close bench. You want strength, stop your bench about an inch or two from touching your chest, go heavy, i mean heavy. when you are done have a friend spot you for four more negatives with a weight you cannot lift normally. 10-15 pounds over your max. This worked for me.
