It's known as advertising. With so many boxers on the forum (obviously it's a boxing forum) it's the exact demographic he's after to sell his product. Explain why this is such an awful idea? I've seen Joe Defranco use a somewhat similar way to strengthen his athlete's necks. I'll post a video when I find it. I don't see why so many people are being pricks and insulting this guy.
