Wow! I re-read Winesburg, Ohio and take a nap, and there are almost 50 new posts!
My Two Cents on Bench Pressing:
I think that it's a mistake to get caught up in bench pressing numbers. That's how pec tears can happen. However, if you really want to increase your numbers, you need to know that the key to benching strength is really in the triceps, and to some extent the shoulders and the back. For a proper benching form:
--rotate your shoulder blades back and up [under you, on the bench].
--'walk' your feet back so that they are under your mid-thigh.
--grip the bar so that it's lying across the meat of your palms.
--bring the bar down under your pecs, not straight down across the tops of your pecs and across you shoulders.
--when you press, allow your elbows to creep forward [toward your hips]. Do not force them to stay at right angles to the bar and to your hands.
This is a powerlifter's benching form. I sincerely believe that it's much safer than the bodybuilder's form, which is basically what's in the 'nots' above. Look
here for more information. The pic on that page is the type of form I'm trying to describe.
Regarding Building Strength:
If you want to build your overall strength on any lift, I think that the best, healthiest, fastest, most vigorous way is to train your back and legs like a fucking Hulk and everything else like a normal person. This means that when you train back and legs, you're pushing yourself to the point of failure all the time, that you're putting as much weight as you can handle on every exercise, and that you're doing as many sets as your body can handle. If you want to be strong [I mean this in a profound sense, not just that you are doing 20lbs more than your friend], you should feel like dogshit at the end of your leg and back workouts. Then, you should do your other exercises [chest, arms, etc] with intensity but not to the point where people look at you funny. If you do this, I honestly believe that you will make faster gains everywhere, not just your legs and back.
Edit: If you are going to do this, you need to eat lots and lots of food.
