Anti-Magic Knights are Fighters who are trained to eliminate casters and magic of all kinds. Typically fighters of this subclass like to make sure that there are no magical shenanigans. They understand how magic works, and how dangerous it is, making sure nothing or no one has magic ever again. They study not just general magic and magical creatures but also casters. How they move and groove or walk and talk they can tell a caster by the way they order they're drink at the local tavern. 

People who become Anti-Magic Knights go through rigorous training and build skills through repetition and the drive to protect the world from magic. They typically wake up early to work out before the day begins, and they like to make sure to get a couple reps in before bed to keep up the muscle. Not all Anti-Magic Knights need much muscle though, as many used ranged options to take out the pests of the world feeding off of the Weave of Magic.
