Glue & screw two 2x4's (or even 2x6's) on edge under where your press mounts.
Maybe another 3/4 inch plywood under your mdf (glued) with the above braces. You don't need to stiffen your whole top. Only the portion under your press and then anchor that part of the bench to the wall or floor.
I assume you are anchoring your table to the wall or floor. Put a brace in the back of the top so you can anchor the top into the wall.
I'm forming obsolete rifle cases on my press with the above bracing and my table top is 2 layers of 1/2 inch USB with 1/4 tempered masonite (glued) on a metal $60 Menard's work bench and it is very stiff. I do anchor it to the wall studs directly behind where the press is on the bench.
Because I care, I carry.
HOPE for the best in people, but PLAN for the worst.
