This question already has an answer here:
Yesterday I went to the cinema and watched Captain America: Civil War, the movie was great IMO, I have no big complaints.
Although, one of the things that bugged me is how come the Winter Soldier didn't break any of his non-enhanced parts of the body, since he is only shown to have a superhuman arm. Also, when Iron Man gets angry at the end of the movie and destroys his enhanced arm he basically can't do anything any more.
There was no on-screen enhancement with a serum as far as I remember in any of the movies. I understand that he is a trained soldier, perhaps the best one in the world (if you don't count cap); but still if he gets knocked into a wall it shouldn't be so easy to recover from.
So if he gets punched by Iron Man (when he stopped holding back) anywhere but in the arm he should get at least some broken bones. Why doesn't that occur in the movie (apart from the plot armor that kinda saved captain america too in the end since it's his movie)?
