CF is all about GPP. It provides a base of all around fitness. The original idea was that you used GPP to stay in general "shape" and then you added in your other goals (extra lifting, endurance, soccer practice, etc.) The problem is that too many CF members take the WOD as all that is needed. It is a helluva workout. I'll often come into the gym and leave 20 minutes later sweating like a pig and breathing very heavily, while the guy on the cell phone is doing his 3rd set of bench presses. The vomiting and rhabado issues are exagerated; I've been doing CF since 2003 and I've never thrown up. It's good stuff but their are many ways to get fit. Just to stir things up, I've included some CF insights from the FAQ.
Here's some insight from Coach on the intent of CrossFit:
"CrossFit is in large part derived from several simple observations garnered through hanging out with athletes for thirty years and willingness, if not eagerness, to experiment coupled with a total disregard for conventional wisdom. Let me share some of the more formative of these observations:
1. Gymnasts learn new sports faster than other athletes.
2. Olympic lifters can apply more useful power to more activities than other athletes.
3. Powerlifters are stronger than other athletes.
4. Sprinters can match the cardiovascular performance of endurance athletes � even at extended efforts.
5. Endurance athletes are woefully lacking in total physical capacity.
6. With high carb diets you either get fat or weak.
7. Bodybuilders can't punch, jump, run, or throw like athletes can.
8. Segmenting training efforts delivers a segmented capacity.
9. Optimizing physical capacity requires training at unsustainable intensities.
10. The world's most successful athletes and coaches rely on exercise science the way deer hunters rely on the accordion."
