Last night I did half of the workout pictured above, but mixed in some presses (95 lb) when I could no longer breath from the burpee pullups. I would recommend using gloves as I tore up my hands a bit. (Also, there's some questionable language in the last 15 sec of the video-please stop before then if you have kids around)
In the quest to build power with endurance, and to become a better athlete, with a more well-rounded approach to health - and also to make me a better, faster triathlete - and because it's just cool to crush yourself in workouts, I've decided to work towards being crossfit.
1) Crossfit's simplified approach: Their definition of Fitness and Health 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.
2) It is undeniable that pushing oneself to the limits increases fitness in a way that walking from machine to machine, doing a slow regimented workout does not. It changes the mind, and has the ability to alter one's composition in a way far more strongly than does the big box gym method.
3) I enjoy pushing my limits.
4) Look around the crossfit site. Watch some of the videos. This is an ethically viable system which doesn't require failing your customers in order to gain a profit.
5) They have cool shirts. One even says "Smoke you like cheap crack" on the back. Gotta love it.
