those guys looks like late part of university, aka 23-25. At this point "being older" means an opposite, they are at peak, and he is an "old man with creaking spine when he leave a chair".
Also, is your "decent build" means "not an anorexic"? Indeed, he isn't sickly thin, but overall he is pathetic. Moreover, with his disposition, he don't have bravery to actually put everything into a punch, and neither he learned martial arts to know how to do it. His punches would be like insect bites. Even one of those "chad" students would overwhelm him easily, and there are two of them.
