Re: New to crossfit... Cost?
Cost really depends on location/coaching quality.
There's a gym in NYC that is $300 a month for unlimited, and worth it. It is own/run by one of the best and most experienced CF coaches, and everything in NYC is pricey because of rent.
$150-200 or so is what I'd expect to pay at an affiliate run by a good coach outside of a major city. Maybe a bit less in areas with a lower cost of living if you get lucky.
There is often a you-get-what-you-pay-for, but not always. I'd expect a LOT for $350/month anywhere outside of NYC/LA. How expensive is it to live in Tyler, Texas?
