You ever use the iron neck? Do you ever know it's a halo? I'll give you one. I have one in the back. It's a halo. You put it on, you pump it up. It fits around your head and then it's got a bungee cord on it. So you back up like this. The bungee cord's 50 pounds. And then you do these. And because it doesn't do this with your neck, it doesn't put pressure on the discs. So it doesn't move the discs in an unnatural way with weight. Yeah, because you can do all these different exercises on it, but it doesn't ever bend your disc, so it strengthens the neck without doing damage to your discs.
