OK wow alot of misinformation here.
First of all you need to set your goals. Is increasing your bench really a priority? Or is muscle mass more important at this stage of your training.
Now if upping your bench is that important for you there are a few things you need to realize.
1. Contrary to popular opinion. Your chest play's a very small role in bench pressing. The pec's major function is as an adductor of the shoulder joint. Not pressing.
So DB flies or cable crossovers will do close to nothing to help your bench. (Find me one good powerlifter who uses them for their bench work)
2. If a one rep max is important you need to train with singles (ME= max effort). Endurance work will actualy hurt your max bench.
3. You want a strong bench you need strong tri's. Try tate presses or JM presses. (check the powerlifting forum).
4. Learn to work on your bar speed. You need to train for speed work or DE (dynamic effort).
There is alot to explain for these principles so it would be best if you research the powerlifting forum. Also check out and read the articles at
