Ah-hah! A topic i can sink my teeth into!

Naturally, if you have access to Wii Fit, you should do that exclusively

Seriously, all the answers you need right now can be found at:

'World-Class Fitness in 100 Words:
Eat meat and vegetables, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat. Practice and train major lifts: Deadlift, clean, squat, presses, C&J, and snatch. Similarly, master the basics of gymnastics: pull-ups, dips, rope climb, push-ups, sit-ups, presses to handstand, pirouettes, flips, splits, and holds. Bike, run, swim, row, etc, hard and fast. Five or six days per week mix these elements in as many combinations and patterns as creativity will allow. Routine is the enemy. Keep workouts short and intense. Regularly learn and play new sports. '
The 'What is Fitness' pdf linked to at the bottom is a great overview of the theory too.
It's all very hardcore and intimidating at first glance, but it really is possible to start this stuff from zero...just takes a bit of research and preparation first. Remember that the official workouts are aimed at ELITE athletes and it may take you months or even years to work up to just being able to complete them as prescribed, never mind crushing them like the folks in the videos.
I started off by doing this programme for about 6 weeks:
http://www.simplefit.org/bodyweight-exercises.htmlBeen at Crossfit for about 7 months now, haven't missed training for anything other than a week or so 'cause of the flu. At age 36, I'm rapidly morphing from a cubicle slug into a lean wall of muscle. It's fun as hell too, especially once you get some friends doing it too to get the competitive juices flowing. You don't even need a gym membership for this stuff if you get some basic equipment. Even if you can't, the bodyweight stuff alone can keep you busy for years.
Also, don't listen to any nonsense DCharlie may tell you about 'running' and 'treadmills'.
