no. its about being an all around elite athlete. it definitely can get you in the best shape of your life. i was for sure, but i was 6'0 175 when i started and dropped 10 pounds. my waistline looked better than ever but i had no chest. i stopped doing crossfit and started a bulking routine and ate a ton and gained 20 pounds, then i bought a bike and im back down to 175 but im bigger and stronger than the last time i was 175. when i did it i wasnt strong enough to do most of the WODs as prescribed unless i wanted to do them really slowly so i was always back and forth between speed and strength. i ran my fastest 5k times without ever training for them. i would just sign up and go run them and do better than i did the last time.
