I'm new to Crossfit as well, and held off signing up for so long because of the cost. I finally sucked it up and just did it, and soooo happy I did...I love it! I still have my gym membership and was contemplating just continuing crossfit on my own after some time so I don't have to pay the crossfit fees. I like the people and the accountability that comes with it too, however, I'm certain I could do the workouts on my own if I had to. Many of them are online, so it's definately possible. I don't push myself as hard on my own, so that's another benefit of they crossfit classes as well.
