If you wrestle (as your name suggest) and you want to stay in a certain weight class, but get stronger, than gaining weight would not be option. There are quite a few 300lb plus bencher's (in regular workouts) at 155-160. It is a matter of increasing the weight load so the body can adapt and progress in handling heavier weight. Might try (as Slave Boy also suggest) sets of 3's for 4-6 sets every bench workout, with (or around) that 225. Do nothing else as a direct chest exercise. Add weight as you get stronger from workout to workout. And you will get stronger. The only extra movement you might do for increasing the bench is the PBN (press behind the neck).
Slave Boy's advise is good about getting confident with any weight used. The more you train the more you find that lifting is just as much a mind game as it is a physical one. And as he said, do not go to failure on any rep. You may try for a one rep max every two week just to see the progress you are making.
If you are a wrestler, than your main concern is not looking pretty like a BB'er but developing functional strength that can be applied to your sport. Some of the strongest athletes I have known, pound for pound, were/are wrestlers. The TUT (time under tension) required for training for that sport goes a long way to develop functional strength. And all from different angles. They are a very powerful group of guy's at what ever bwt.
I really do not understand why some may think that eating is the prime answer to becoming stronger. If may be part of the whole but not the main factor. Might be why a lot of BB'ers wind up looking like the Phillsbury Dough Boy. Good Luck.
