A half dozen Crossfit facilities have popped up in my city since 2007 and have attracted coaches (people needing jobs) with limited or no experience and one certification (eg. Crossfit Level I). This trend concerns me and I’m not comfortable recommending this type of training to most people.
It depends on the definition of novice and what activity level the client is actually presenting.
Generally speaking, it is not a good fit for novice to do crossfit.
Take care.
