I was reading up on the exercise program the actors did for the 300 movie (http://www.gymjones.com/). They seem to have used workouts that were between cardio and weight training. So, if you have a gym where you can drag tractor tires, climb rock walls, toss medicine balls, do pull-ups on monkey rings, etc - well then, you got it made. Otherwise, for the rest of us, a good variety of cardio and weight training is probably a good idea. (Variety being the key word.)
Also, from reading GymJones and all the other exercise material that I've read, it seems that diet is like 60% of getting the body you want (30% exercise and 10% rest - or something close to that). Bottom line, you gotta make sure you're eating less calories than your body takes to make fat. Then, you'll start burning off your fat (of course, make sure you don't start burning off your muscle ^_^).
Because diet is such an important factor, you gotta use a program to track what you eat. Gyminee is perfect for that. Log what you eat for several months and see what works. Each person's body is different and so you have to find what caloric intake level works best for you.
I'm in the bulking stage right now. So for me, I try to eat around 3,000 clean calories a day (easier said than done). But, in the past I've been on a 2,000 calorie diet and I could see my abs start popping out. Speaking of my 2,000 calorie diet - here in MN they have this food delivery service called Seattle Sutton's Healthy Eating (http://www.seattlesutton.com/). It can get a little expensive, but I felt healthier and looked better than ever while on that program. The food does start tasting a little boring after like 3-4 months. But, for me it's perfect, I cut for about 3-4 months, then I spend the rest of the year trying to gain mass. Once I get big enough I'll probably have to do something different. But for now this system seems to be working.
This is probably more information than you were asking for. :) Hope it helps.
