I'm entering a bench meet at my gym just for fun (and some money and a free membership). The meet is this coming up Saturday at noon. I was just wondering, for those with experience, how should I do my training this week and how should I do my warmup sets the day of the meet.

Here's a bit more info on my training:
Typically I do my split like this.

I added another chest day yesterday in which I did some heavy band work with reps in the 2-5 range.

I'm weighing in at 193 lbs right now and my first attempt will be my surefire weight of 390. I'll probably attempt 405 afterwards. If I get that, then who knows.

I haven't lifted heavy since I began my 30lb cut in March.

And this is a raw meet.
