The exercises mentioned for your back pretty much cover it. I wanted to touch a bit more on the dropping the bench advice. First, it must be heeded. Second, drop the bench completely. I did no benching whatsoever for 2 years, just dips. My bench, when I did finally go back to it (per AM), was still over 300. Which is 1.5 times my bw, so I didn't lose much. My pecs also flattened out nicely during this time, which I attribute to both my diet and the dips.
Also, you sound as though you are interested in appearance. Which I would then jump to the conclusion that you are lifting to look better. A study printed not long ago showed that women think the sexiest parts of men are their ass, calves, and thighs. In that order I believe. Arms and chest came in last.
Now the question.....Why is it that so many men lift to look better for women, yet don't even focus on what women like? In fact, the only people who appreciate big arms and chests, are other men. Maybe keep that in mind in order to aid you in focusing on that back and legs.
But what do I know........I'm married, lift for strength, and would much rather wear bikini briefs and a sweatshirt, than Zubaz and a wife beater!
