ONCE A WEEK IS ENOUGH!
I have only benched once a week (each body part once a week for a 5 day training week) for the past 3-4 years and i have a large chest~48-49". Secondly, my bench is my best exercise by far, about 2 months ago i did 5x5 with 405 and last week i finished with 405 for 7 reps.
BARBELL, BARBELL, and MORE BARBELL!
mix and match:
flat barbell followed by incline dbs
flat barbell followed by incline barbell
inlcine barbell with flat dbs
incline barbell with flat barbell
rest pauses at the end of your routine (rest at the bottom for 1 second)
mix and match your reps/sets:
3 sets of 10 at the same weight
5x5
sets of 8-10 pyramiding up
sets of 5-6 reps as high as you can go
NOTE: Please dont just add 5lbs to the bar at a time if you are pyramiding. I feel that the pecs are large enough to handle a minimum of a 20lb increase (im up to 40-50lb jumps). If you are not accustomed to this style, then try to approach it, up it 10lbs then till that is comfortable then go up to 20 and so on. If this means you have to warm up with the lighter weight, then please do so, you will reek the benefits.
Lastly, if your upper pecs are lagging, then predominately start with incline.
Also, overall shoulder development is crucial, that means not forgetting about the side and rear delts. Your triceps are crucial too, try incorporating close-grip bench in for your tris. This will give you your second bench day, but predominately focus on your tris.
Hope this helps.
