its called "shocking" your muscles, you have to mix it up. try incline for a week then do decline for a week, then do military for a week, then do say flat benches. by hitting the same muscle groups from different angles you ripping them in different places making them grow while actually givening the other part of that muscle time to rebuild. get a weider book that'll get you goin.

I'm 130 as well and my max so far is 185 for about 5, i've recently started a 5 by 5 program low rep high weight and i've seen some very nice gains. I jumped from my max of 155 - 185 in about 2 and a half weeks! just figure out what works for you

That is very easy. I am surprised that you are worried so much about bench press though. You should be more worried about your squat and deadlift. But anyways, if you want your bench to increase, on your upper body workout days, you should do about three sets of 6-8 of about 70%, 75%, 80% of your max respectively in all of the bench variations. That is normal, incline, decline, normal grip, and close grip. Make sure that when you do these exercises that you keep your elbows in tight to your body. That is because you need to lift sport specifically. When are you going to push someone with your elbows spread out wide? And always on your last set, lift to failure. You should not even be able to lift the weight on your last rep of your last set. That is where you build most of the strength and the spotter should be there to just use one finger to help lift the bar. Make sure that you keep your breathing and do not turn your head while lifting. . If you still have extra time to lift or need to do more, you can do a burnout or variation. For your size, you should probably do this with ten pound plates. What you do is start with just the bar and bench press it ten times by going down on a slow 4 count and come as close as you can to touching your chest and pushing it as hard as you can up. After ten reps, hold the bar up and two extra spotters on the side should put one ten pound plate on each side. Then do ten more reps the same way. After ten, the two extras put on another ten each. Do ten more. Then after ten, the two extras should take off one plate. Do ten more, and then the spotters should take off the remaining plates and then do ten with just the bar. Repeat this process until you can no longer lift the the weight on your own. . You should also work on your core daily.
