Is the Red Zone a Real Thing?

Is the red zone a real thing? Because I don't think I've ever been there. You wear a heart monitor and everything and then like your heart rate is up there. You try to get to the orange zone. And that's the theory. So they know if you're taking it easy or not. We had, we had an idea a few months ago. It's called 16 weeks to glory. But I just thought I was just branding. Since we're talking about fitness, I got to tell you something. Sometimes we have an idea and we talk it through and we're like, that's not a good idea. But then it doesn't go away. Every week.
