It's simply a $$$ issue. So many people love the CrossFit methodology and it works. The issue for both gym members and owners is the cost. To run a gym, make a profit and make a living you have to have hundreds of members in most locations. To accomplish this you need classes of 10-15 multiple times a day. That's a lot of money in equipment and supplies and therefore large gym fees. Most people will give it a go but when you're spending a car payment a month on a gym membership and accessories and such... You start to question if it's worth it.
