How practical is it to dodge punches by leaning back table top like similar to how Neo did in the first matrix movie during a boxing match and also counter from that position. It has always been one of my favorite scenes in media and I have seen it being used in fictional boxing media of watch and read such Hajime no Ippo and the Boxer. I know that trying to copy moves you seen in fantasy is generally looked down upon and can be unsafe and generally not realistic. But it seems at least somewhat possible so I'd to see to what degree just for the sake of my curiosity.
You can dodge punches but doing so by leaning backwards is usually a really bad idea.
I believe I have seen some boxers do it when against the ropes, but only really to show off.
The issue is that you risk taking a punch to the stomach that you can't easily see. Also you are obviously off balance because physics will apply to you in a way it doesn't in the matrix movie.
It's bad structurally and it's bad for your view of the opponent. There is no payoff other than looking cool (and you won't look cool when you get hit).
