As a boxing coach, I am a firm believer that all fighters should train the neck diligently. In fact, I’d further that recommendation to anyone involved in a contact sport (ex. football, rugby, wrestling, etc.). A strong neck will undoubtedly help to prevent injury. Unfortunately, many athletes ignore neck training until there’s a problem. In other words, they react to an injury, rather than proactively training the neck all along.
Don’t make that mistake.
