But here´s the thing i know people who can overhead press with a decent weight but are shit at Benches. Barbell Military press is a great exercise too, even hits some chest. not saying like a flat bench does but it does gives some bouncy

stimulation. i mean if you do incline presses you do not need an overhead press or vice versa. No need for an incline bench if doing good heavy front press on machine or barbell.
