Josh is right.
The point is efficiency. If you're training for strongman, then your focus will be on the stuff Josh listed, "push jerks, push presses, military press", as well as log, axle, db press, incline, lockout work. Is there really a point to include flat bench work? Could your time be better spent on something else?
The guy Josh is speaking of trains with the AZ crew and hit 12 reps on the 260 log in his first strongman contest. He comes from an olympic lifting background. That many reps is national level standards and this guy probably only flat benches every full moon.
Another former olympic lifter that is a world class overhead presser that you may have heard of once or twice. . . Jesse Marunde.
