Workout Program?

You must be huge. Doing 315 for reps of any amount is an accomplishment by itself. That being said I don't think anyone should be doing that much weight without a spotter it's just dangerous. However if you want to break a plateau you should do bench with dumbells for a few weeks as heavy as you can go and focus on negatives. You should also focus on heavy incline and decline bench for balance if you aren't doing it already.
