Like what @scytale@piefed.zip said, it depends on what “action” means. If action just means having fight scenes in them, then plenty of sports anime with flashy sequences meet the criteria. Or anything with a heavy focus on competition and rivalry.
Some of my favourites - that are most relevant to this post - are Haikyu and anything from Umamusume.
For Umamusume, the more “battle shonen-like” ones are Beginning of a New Era and Cinderella Gray IMO. (Even though Cinderella Gray is supposedly seinen.)
