I lift as well. I started a few years ago, and got a lot of useful advise from GPW. In fact, he was the first person to give me sound advise, which I appreciate.
There is a lot of crap on the internet, some of which seems baseless. In fact, a lot of people seem to take things as fact because it is generally accepted and not out of some scientific basis. I'd listen to GPW. It isn't complex, and it should be logical, that's it. Most of the generally accepted facts seem to be correct though. GPW's entire paragraph about working specific muscle areas and stuff is correct.
Here is what I do, and if someone feels I am incorrect, please point it out:
* Work on chest doing standard and decline benchpresses Day 1
* Work on chest doing standard and incline dumbbell bench presses, dumbbell fly presses, on Day 2
* Work on forearms, shoulders, and biceps using heavy weights Day 3
* Take a break Day 4.
* Work on forearms, shoulders, and biceps using lighter weights with longer reps Day 5.
* Work on triceps and shoulders Day 6
* Either take a break Day 7 or do a light workout.
I probably should be doing more for the triceps and legs, but I don't find that fun. I normally hit the exercise bike before every workout though.
If you are going to pump heavier weights with shorter reps, then you will increase mass. The more reps you do, the more tone you will achieve, but obviously you will have to lighten the load with lighter weights.
Some of my favorite exercises, that seem to have benefited me the most:
1. Benchpress. Might seem like a cliche or whatever, but there is nothing like it. Different grips can work different chest muscles. You can also do standard, inclined, and declined benchpresses to work different areas of your chest. It also does well for your shoulders.
2. Arnold Dumbell press: I love this exercise.
