I read the title and thought you were looking for villagers whose designs make them look like boxers. Villagers specific to boxing. So I came here to tell you Rooney the Kangaroo is wearing boxing gloves. lololol
Anyway, I cycle in my second town and use the foolproof cycling method. It's super easy, but it won't work if there are villagers you want to keep.
If there are villagers you want to keep and you're just trying to get one or two villagers out, you basically have to TT slowly and carefully or be patient.
