CrossFit is taking the world by storm and establishing itself as an independent sport in it's own right - the sport of fitness. Credited with creating the 'fittest on earth' the CrossFit methodology is one built around total-fitness, specialising in being the anti-specialist.
In their own 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.
