ego training.... hehe, kidding
The floor press is a known powerlifting technique and should help. You can always hit a bench program. Max outs, just really aim for strength in your flat bench lift, and that alone, should give you an up on your bench max/strength. Also, keep in mind, your pecs arent the only thing pushing that weight up. You gotta have strong tris, front delts, lats, and of course.... form. So bring those up and definitley, your bench will go up as well
