Will I/Can I Get Big Doing CrossFit?

If you train the WODs hard, and eat right and get lots of sleep, you will definitely gain lean mass, lose fat, and yes, you can build muscle mass with the crossfit protocol. More specifically, according to Coach,Here is a hierarchy of training for mass from greater to lesser efficacy:

1. Bodybuilding on steroids

2. CrossFitting on steroids

3. CrossFitting without steroids

4. Bodybuilding without steroids

The bodybuilding model is designed around, requires, steroids for significant hypertrophy.The neuroendocrine response of bodybuilding protocols is so blunted that without "exogenous hormonal therapy" little happens. The CrossFit protocol is designed to elicit a substantial neuroendocrine whollop and hence packs an anabolic punch that puts on impressive amounts of muscle though that is not our concern. Strength is. Natural bodybuilders (the natural ones that are not on steroids) never approach the mass that our ahtletes do. They don't come close. Those athletes who train for function end up with better form than those who value form over function. This is one of the beautiful ironies of training.
