That’s one heck of a hobby. For those interested in doing so in this country, you can just go to the National WWI memorial in Kansas City to see a recreated trench section, then take up some less rigorous hobby instead
I’ve been to the WWI museum in KC. It’s utterly fascinating and highly recommended.
I haven't been to the memorial in Kansas City, but I have been to the memorial at the Imperial War Museum in London. It was pretty good.
They had a shelter room where you could sit with others and they simulated bombs blowing up on the surface with loud booms and the room would shake. Wait, that may have been the simulator for the WWII Blitz.
