I can assure you, that most people despite being able to bench
90kg might not even be able to handle a 60kg military press.Simply
put, their lower back is too weak to support.
There was this case where i persuaded a guy to try military
presses, he can bench 95kg but struggles with a light weight like
42.5kg with military presses.If you are sceptical about this, try
experimenting it with a person who does bench press only all the
time.
I am not saying bench press is bad but rather over- prescirbed.I
recommend doing/alternating both.
Military press is this case is standing up with dumbbells or
barbells.
