Re: Looking for info on starting a box in WA state
Very first step should be visiting several affiliates and talk to the owners. See how they are run. Learn from their mistakes if they are willing to share.
Second, if you have no business sense, buy a book, take a class...training is great, but you will need to learn how to make money in your business to keep the doors open.
Third, legally to operate, the L1 cert is what you need. But, you will be doing a great disservice to CrossFit, and to your members, IF, you think will be able to properly train anyone following your L1 cert without any prior knowledge on anatomy, physiology, kinesiology, etc. in order to be a well rounded, knowledgeble trainer. After you get the cert, your learning CANNOT stop! Not just CF certs, but books, seminars, etc. will help more than you can imagine right now.
