HELL YEAH! Ripped up man! lol j/k
Bodybuilding without steroids over Crossfit without steroids, just don't follow the typical BB'ers routine. More days off, high intensity short workouts COMPOUND movements.
Remember crossfit is great for what it is though, all around fitness. But if you want specific goals (mass gain, strength gain) you might want to look elsewhere like 5x5 barbell routines and Starting Strength.
Just remember I am not dissing crossfit, just don't hype it up so people have unrealistic hopes about the program!
