Mario Lopez is one of OK!’s picks for the sexiest men of the year. And fittingly, the hunk with the six-pack abs is working on a fitness book for the coming year.

“I’m really excited about the book,” he tells OK! “It’s untitled at the moment but is coming out in the spring and is for both men and women and for all fitness levels. You can be as intense as you want with it. I’ve really been upping my training because of it. I box three times a week; I ride bikes, run, play racquetball, do yoga and weight training. I really try to keep it diverse.”

Mario also still struts his stuff on the dance floor. He finished second to football great Emmitt Smith on season three of Dancing With the Stars and will be performing on one stop of the DWTS Tour on Dec. 27 in San Diego. “That’s my home town and I’m already going to be there during the holidays. I figure I get to perform for my family and friends there. They’ll get a kick out of that.”

He doesn’t starve himself to get his incredible body. “I try to graze like a goat all through the day with small meals, eating every few hours.”
