Ab-tastic Daniel Dae Kim & male supermodel Marcus Schenkenberg swordfight 41 today.

Obviously, Marcus is paid to be a hot bitch and his routine reflects a dedicated gym rat. An article about his routine revealed he does 10-15 minutes of cardio warm-up, and work different muscle groups each day. He works his abdominals every day: four sets of about forty crunches, in four different positions to work different muscle groups, during which he
focuses on keeping his stomach sucked in, so the muscles don't develop bulged-out.

Mon: Chest, bis, tris, abs.
Tues: Legs, abs.
Wed: Shoulders, back, forearms, abs
Thurs: Rest.
Fri: Chest, bis, tris, abs.
Sat: Legs, abs.
Sun: Shoulders, back, forearms, abs.

Daniel says he doesn't have a specific routine, he does "try and do something active -- running, hiking or playing tennis," he says. According to
Men's Health, he runs 3 to 4 miles 3 or 4 days a week and trains with weights on the same days. To keep his workouts moving at peak efficiency, "I don't take long breaks between sets," he says.

Daniel turns 40 today. A big reason to keep active in your 30's? To stay fit and look hot BEYOND them.
