First of all ... going from 275lb max to 315lb max in 2 months is not a reasonable goal. That's a huge increase and some people don't ever make it that high.

Second ... how many exercises do you do each workout? Looks like probably too many but you don't say specifically. I would focus on each big lift per day and support that with 2 or 3 accessory exercises at most.

Thirdly, if you want to get strong you have to EAT. Lots. You're already doing good with your food choices but you need more than 3 meals a deal. The more consistent and spread out the nutrition is over the course of a day, the better. Any way to get a snack in between meals?

Just some thoughts from a guy who has yet to bench 275lb after many years of training. It's always been my weak point.

My best lifts as of now (just for fun):
Bench: 260lb x 2
Deads: 440lb x 4
Military Press: 195lb x 2
Squat: 335lb x 4 (A2G)

@ ~220lb / 6' / 15-17% BF (guess)
