CrossFit is actually an open source program in which you're free to follow the Workouts of the Day on the main site. There are many reasons why I pay more than a typical gym to train at my location. The results I've gotten in the past six months wouldn't be attainable without the coaching from my trainers. I see too many people at the typical gym using poor range of motion and technique. It's probably the best thing I've ever invested for my health. I currently deadlift at 325lbs, my best time for a mile is 6:28 and I'm able to do a couple of handstand push-ups .

People can complain it's too expensive, but it's pretty much a given you won't get the same results working on your own compared to going to a CrossFit gym.
