You want me to put you on the cover of men's fitness. You think you're up for it? Wolverine wannabe casey braxton. Could we convince 33-year-old casey to let his inner jackman claw himself out? I don't know about the abs, though. I like to eat too much. But I think we could do it. Reporter: And so, casey was in. Sorry spidey. It's just not your weekend. 18-year-old hitch from new jersey -- think this could be you? Yeah, sure. Reporter: On board, too. Still, I wanted to clinch this.

Is that a farmer's tan he's sporting? Sideways. Finally, 50-year-old kurt, a self-proclaimed artist by day, silver fox by night. That''s perfect. He was going to need more than a coat of paint to make himself camera ready. Are we going to keep the mask on? Yes. Reporter: Upstair us, the "men's fitness" dream team. A stylist, a groomer, the photo director. And sticking with andrew dixon's edict, we gave them just 60 minutes to snap those six packs. You have two brothers?
